  1. Fulltext Enhancing animal protein supplies in Malaysia: opportunities and challenges
    Devendra, C.
    ASM Science Journal, 2007;1(1):63-73.
    MyJurnal
    The increased human demand for animal proteins in Malaysia is led by several factors: population growth, urbanisation, income growth and changing consumer preferences. Meeting the projected increased demand in the future is an awesome and challenging task. Presently, the non-ruminant poultry and pig industries, mainly private sector led, make the most significant contribution to total animal protein supplies, and inefficient ruminant production systems lag well behind. The strategy for promoting productivity growth to increase animal protein supplies from ruminants requires concerted efficient natural resource management that can target specific production systems. Two distinct economic opportunities are the development of oil palm-based cattle and goat production. The value addition to oil palm cultivation due to the beneficial crop-animal-soil interactions are enormous. The prerequisites are inter-disciplinary efforts, holistic systems, participatory community-based research and development that are needs-based and address constraints, increased research investments, institutional commitment and a policy environment that can enhance total factor productivity in the future.

  2. Policy challenges and approaches for the conservation of mangrove forests in Southeast Asia
    Friess DA, Thompson BS, Brown B, Amir AA, Cameron C, Koldewey HJ, et al.
    Conserv Biol, 2016 10;30(5):933-49.
    PMID: 27341487 DOI: 10.1111/cobi.12784
    Many drivers of mangrove forest loss operate over large scales and are most effectively addressed by policy interventions. However, conflicting or unclear policy objectives exist at multiple tiers of government, resulting in contradictory management decisions. To address this, we considered four approaches that are being used increasingly or could be deployed in Southeast Asia to ensure sustainable livelihoods and biodiversity conservation. First, a stronger incorporation of mangroves into marine protected areas (that currently focus largely on reefs and fisheries) could resolve some policy conflicts and ensure that mangroves do not fall through a policy gap. Second, examples of community and government comanagement exist, but achieving comanagement at scale will be important in reconciling stakeholders and addressing conflicting policy objectives. Third, private-sector initiatives could protect mangroves through existing and novel mechanisms in degraded areas and areas under future threat. Finally, payments for ecosystem services (PES) hold great promise for mangrove conservation, with carbon PES schemes (known as blue carbon) attracting attention. Although barriers remain to the implementation of PES, the potential to implement them at multiple scales exists. Closing the gap between mangrove conservation policies and action is crucial to the improved protection and management of this imperiled coastal ecosystem and to the livelihoods that depend on them.

  3. Connecting science, policy, and implementation for landscape-scale habitat connectivity
    Brodie JF, Paxton M, Nagulendran K, Balamurugan G, Clements GR, Reynolds G, et al.
    Conserv Biol, 2016 10;30(5):950-61.
    PMID: 26648510 DOI: 10.1111/cobi.12667
    We examined the links between the science and policy of habitat corridors to better understand how corridors can be implemented effectively. As a case study, we focused on a suite of landscape-scale connectivity plans in tropical and subtropical Asia (Malaysia, Singapore, and Bhutan). The process of corridor designation may be more efficient if the scientific determination of optimal corridor locations and arrangement is synchronized in time with political buy-in and establishment of policies to create corridors. Land tenure and the intactness of existing habitat in the region are also important to consider because optimal connectivity strategies may be very different if there are few, versus many, political jurisdictions (including commercial and traditional land tenures) and intact versus degraded habitat between patches. Novel financing mechanisms for corridors include bed taxes, payments for ecosystem services, and strategic forest certifications. Gaps in knowledge of effective corridor design include an understanding of how corridors, particularly those managed by local communities, can be protected from degradation and unsustainable hunting. There is a critical need for quantitative, data-driven models that can be used to prioritize potential corridors or multicorridor networks based on their relative contributions to long-term metacommunity persistence.

  4. Estimating farmers' willingness to pay for climate change adaptation: the case of the Malaysian agricultural sector
    Masud MM, Junsheng H, Akhtar R, Al-Amin AQ, Kari FB
    Environ Monit Assess, 2015 Feb;187(2):38.
    PMID: 25632900 DOI: 10.1007/s10661-014-4254-z
    This paper estimates Malaysian farmers' willingness to pay (WTP) for a planned adaptation programme for addressing climate issues in the Malaysian agricultural sector. We used the contingent valuation method (CVM) for a monetary valuation of farmers' preferences for a planned adaptation programme by ascertaining the value attached to address climatic issues in the Malaysian agricultural sector. Structured questionnaires were distributed among the sampled farmers. The study found that 74 % of respondents were willing to pay for a planned adaptation programme and that several socioeconomic and motivation factors have greater influence on their WTP. This paper clearly specifies the steps needed for all institutional bodies to better address issues in climate change. The outcomes of this paper will support policy makers to better design an efficient adaptation framework for adapting to the adverse impacts of climate change.

  5. Plant-driven removal of heavy metals from soil: uptake, translocation, tolerance mechanism, challenges, and future perspectives
    Thakur S, Singh L, Wahid ZA, Siddiqui MF, Atnaw SM, Din MF
    Environ Monit Assess, 2016 Apr;188(4):206.
    PMID: 26940329 DOI: 10.1007/s10661-016-5211-9
    Increasing heavy metal (HM) concentrations in the soil have become a significant problem in the modern industrialized world due to several anthropogenic activities. Heavy metals (HMs) are non-biodegradable and have long biological half lives; thus, once entered in food chain, their concentrations keep on increasing through biomagnification. The increased concentrations of heavy metals ultimately pose threat on human life also. The one captivating solution for this problem is to use green plants for HM removal from soil and render it harmless and reusable. Although this green technology called phytoremediation has many advantages over conventional methods of HM removal from soils, there are also many challenges that need to be addressed before making this technique practically feasible and useful on a large scale. In this review, we discuss the mechanisms of HM uptake, transport, and plant tolerance mechanisms to cope with increased HM concentrations. This review article also comprehensively discusses the advantages, major challenges, and future perspectives of phytoremediation of heavy metals from the soil.

  6. Idolization and ramification between globalization and ecological footprints: evidence from quantile-on-quantile approach
    Sharif A, Afshan S, Qureshi MA
    Environ Sci Pollut Res Int, 2019 Apr;26(11):11191-11211.
    PMID: 30796670 DOI: 10.1007/s11356-019-04351-7
    Globalization persists the tendency to alter numerous aspects of today's world including religion, transport, language, living styles, and international relations; however, its potential to influence quality of environment is the prime concern for trade and environmental policies guidelines (Audi and Ali 2018). In response to the growing interest for identifying the dynamic relationship between globalization and environmental performance, the present study seeks to investigate the critical link between globalization and ecological footprints in top 15 globalized countries between 1970 and 2016. Applying the novel methods of quantile-on-quantile regression (QQ) and Granger causality in quantiles, the findings examine the manners in which quantiles of globalization affect the quantiles of ecological footprints and vice versa. The empirical results suggest that globalization has a long-term positive effect on ecological footprint and vice versa in case of Belgium, the Netherlands, Sweden, Switzerland, Denmark, Norway, Canada, and Portugal. On the other hand, the estimated results indicate a negative effect between globalization and ecological footprint in the case of France, Germany, the UK, and Hungary. These results extend the recent findings on the globalization-environment nexus implying that the magnitude of relationship among both variables varies with countries demanding individual focus and cautions for postulating environmental and trade policies.

  7. Assessing the mechanism of energy efficiency and energy poverty alleviation based on environmental regulation policy measures
    Wu B, Liu S, Wang J, Tahir S, Patwary AK
    Environ Sci Pollut Res Int, 2021 Aug;28(30):40858-40870.
    PMID: 33772472 DOI: 10.1007/s11356-021-13605-2
    This work aims to assess multidimensional energy poverty and energy efficiency for environmental policy measures using data envelopment analysis (DEA), a DEA-Like mathematical composite indicator applied on a dataset based on multiple sets of variables from South Asian economies. The multidimensional energy poverty index (MEPI) is computed to analyze the combining effects and energy poverty in these countries. Simultaneously, South Asia's metropolitan areas' population rose by 130 million between 2001 and 2011 and is projected to expand by approximately 250 million by 2030. The findings reveal that endogenous increasing population shocks account for about 72% of energy use. In contrast, the long-term effects of remittance revenue, economic growth, and urbanization on energy use are approximately 20%, 8.25%, and 0.03%, respectively. This work advocates more coordinated and innovative policies to eliminate energy poverty. It can act as a base for policymakers and government officials to make efficient policies and enforce them properly in the regional power sector. Policies should be designed around a smarter use of biomass for cooking, alternate sources for domestic energy production, increased programs for biomass-based cookstoves, and periodic regional-level energy database development.

  8. Fulltext Can the carbon emissions trading improve the enterprise environmental responsibility?
    Chen H
    Environ Sci Pollut Res Int, 2023 Jun;30(29):73361-73371.
    PMID: 37184784 DOI: 10.1007/s11356-023-27520-1
    Carbon emission trading is an important environmental policy tool to promote carbon emission reduction. With the panel data of carbon emissions trading (CET) pilots, this paper used the spatial difference-in-difference model (SDID) to test whether CET can affect the enterprise environmental responsibility and the spatial spillover effect of carbon emissions trading. The study found that CET can significantly improve the environmental responsibility level of enterprises in pilot areas. The environmental responsibility level of enterprises in surrounding areas are also improved driven by CET. In the time dimension, the role of CET in improving the enterprise environmental responsibility is gradually increasing. The impact of CET on enterprise environmental responsibility has significant heterogeneity in the dimension of ownership attributes and environmental regulation. Promoting corporate environmental protection investment is the main path for CET to improve the enterprise environmental responsibility.

  9. The moderating role of CEO power on the relationship between environmental, social and governance disclosure and financial performance in emerging market
    Al-Ahdal WM, Farhan NHS, Vishwakarma R, Hashim HA
    Environ Sci Pollut Res Int, 2023 Aug;30(36):85803-85821.
    PMID: 37393591 DOI: 10.1007/s11356-023-28499-5
    The study proposes to examine how environmental, social and governance disclosure (ESG) affect the financial performance (FP) of Indian firms. Furthermore, it aims to evaluate the moderation impact of CEO power (CEOP) on the association between ESG on the FP. The study's target population is all firms indexed in NIFTY 100, representing the top one hundred firms by market capitalisation from 2017 to 2021. Data relating to ESG were collected and built based on the available data on Refinitiv Eikon Database. Results reveal that EDI positively and significantly impacts the ROE and TQ of Indian firms. Furthermore, SDI and GDI negatively and significantly affect the ROE and TQ of Indian firms. Moreover, ESG and CEOP have a significant impact on ROE. Nevertheless, ESG has a negative but highly significant impact on ROE, whilst it has a negative and low considerable impact on the TQ of Indian firms. Nonetheless, CEOP does not moderate the association between ESG and FP measured by ROE and TQ. This research contributes to the existing literature by introducing a moderator variable that has not been used in the Indian context; CEO power, which provides stakeholders and regulators with useful findings that would encourage firms to create an ESG committee to enhance ESG disclosure to compete on the world market and reach the United Nations (UN) Sustainable goal 2030. Furthermore, this paper provides insightful recommendations for creating an ESG legal framework for decision-makers.

  10. Revisiting the environmental Kuznets curve: assessing the impact of climate policy uncertainty in the Belt and Road Initiative
    Huang Y, Rahman SU, Meo MS, Ali MSE, Khan S
    Environ Sci Pollut Res Int, 2024 Feb;31(7):10579-10593.
    PMID: 38198084 DOI: 10.1007/s11356-023-31471-y
    Climate change repercussions such as temperature shifts and more severe weather occurrences are felt globally. It contributes to larger-scale challenges, such as climate change and biodiversity loss in food production. As a result, the purpose of this research is to develop strategies to grow the economy without harming the environment. Therefore, we revisit the environmental Kuznets curve (EKC) hypothesis, considering the impact of climate policy uncertainty along with other control variables. We investigated yearly panel data from 47 Belt and Road Initiative (BRI) nations from 1998 to 2021. Pooled regression, fixed effect, and the generalized method of moment (GMM) findings all confirmed the presence of inverted U-shaped EKC in BRI counties. Findings from this paper provide policymakers with actionable ideas, outlining a framework for bringing trade and climate agendas into harmony in BRI countries. The best way to promote economic growth and reduce carbon dioxide emissions is to push for trade and climate policies to be coordinated. Moreover, improving institutional quality is essential for strong environmental governance, as it facilitates the adoption of environmentally friendly industrialization techniques and the efficient administration of climate policy uncertainties.

  11. Research trend in Sustainable Development Goals reporting: a systematic literature review
    Low SM, Abdullah DF, Khatib SFA
    Environ Sci Pollut Res Int, 2023 Nov;30(52):111648-111675.
    PMID: 37821734 DOI: 10.1007/s11356-023-30122-6
    This paper examines the common themes delivered in studies on corporate reporting in relation to Sustainable Development Goals (SDGs). Articles of the aforesaid studies were mostly acquired from Scopus and Web of Science (WoS) archives from year 2015 to 2022 in which the contents were carefully reviewed for selection. To systematise the literature, PRISMA 2020 statement is used. Descriptive analysis reveals an increase in publications on corporate SDG reporting, although most are focused on developed nations. The analysis also shows a scarcity of studies on the consumer goods, agricultural, fishery, and forestry sectors. Furthermore, current studies have yet to adopt a qualitative or mixed-method approach. There are fundamentally six themes that emerged from the review of literature-the degree of SDG engagement, the quality of SDG reporting, the determining factor in SDG reporting mechanism, the consequences of SDG reporting, the legitimisation approaches, as well as the institutional/stakeholder pressure. For determinants of SDG reporting, it is observed that environmental governance is not explored. This paper identifies the least addressed SDGs that businesses can focus on to accelerate their SDG contribution rate. This paper guides future research and informs decision-making by organisations and stakeholders interested in promoting sustainable development through SDG reporting.

  12. Green finance and environmental, social, and governance: evidence from Chinese listed companies
    Wu J, Liew CY
    Environ Sci Pollut Res Int, 2023 Nov;30(51):110499-110514.
    PMID: 37792189 DOI: 10.1007/s11356-023-30139-x
    In recent years, academics have paid more attention to green finance, and public companies have reached a broad consensus on the concept of timely environmental, social, and governance (ESG) disclosure. Due to the close relationship between green finance and ESG, this presents an opportunity to determine whether green finance compels companies to actively disclose ESG. The sample for this study consists of China's non-financial A-share listed companies from 2010 to 2021, and the empirical findings demonstrate that green finance can positively influence the ESG performance of listed companies. Through an analysis of heterogeneity, this study reaches the following conclusions: state-owned enterprises, heavy pollution companies, and companies in low-carbon pilot cities perform better in terms of green finance's role in promoting ESG scoring. This study also introduces market concentration and social trust as the moderating variables, enriching the green finance research framework. Through the analysis of moderating variables, the 'black box' effect of green finance on ESG is disclosed, providing theoretical support for the government and companies to better comprehend the policy effect as well as a reference for reform and experimental promotion of green finance.

  13. Geopolitical risk, financial development, and renewable energy consumption: empirical evidence from selected industrial economies
    Ben Abdallah A, Becha H, Sharif A, Bashir MF
    Environ Sci Pollut Res Int, 2024 Mar;31(14):21935-21946.
    PMID: 38400971 DOI: 10.1007/s11356-024-32565-x
    The rapid rise in climate and ecological challenges have allowed policymakers to introduce stringent environmental policies. In addition, financial limitations may pose challenges for countries looking to green energy investments as energy transition is associated with geopolitical risks that could create uncertainty and dissuade green energy investments. The current study uses PTR and PSTR as econometric strategy to investigate how geopolitical risks and financial development indicators influence energy transition in selected industrial economies. Our findings indicate a non-linear DCPB-RE relationship with a threshold equal to 39.361 in PTR model and 35.605 and 122.35 in PSTR model. Additionally, when the threshold was estimated above, financial development indicators and geopolitical risk positively impacts renewable energy. This confirms that these economies operate within a geopolitical context, with the objective of investing more in clean energy. We report novel policy suggestion to encourage policymakers promoting energy transition and advance the sustainable financing development and ecological sustainability.

  14. Fulltext Evaluation of the Policy Effect of China's Environmental Interview System for Effective Air Quality Governance
    Jin X, Sumaila UR, Yin K, Qi Z
    Int J Environ Res Public Health, 2021 08 26;18(17).
    PMID: 34501589 DOI: 10.3390/ijerph18179006
    The Ministry of Ecology and Environment of the People's Republic of China formally proposed an environmental interview system in May 2014, which applies pressure on local governments to fulfill their responsibility toward environmental protection by conducting face-to-face public interviews with their officials. In this paper, 48 cities that were publicly interviewed from 2014-2020 were considered the experimental group and 48 cities surrounding them were the control group. First, the dynamic panel model is applied to initially determine the effect of the policy. Then, a regression discontinuity method (Sharp RD) is used to analyze the short-term and long-term effects and compare the reasons for the differences observed among the estimates of various types of samples. Finally, a series of robustness tests were also conducted. The results show that the environmental interview system can improve air quality. However, because an emergency short-term local governance system exists at present, the governance effect is not long-term and, therefore, not sustainable. Therefore, it suggests that the government should continue to improve the environmental interview system, establish an optimal environmental protection incentive mechanism, and encourage local governments to implement environmental protection policies effectively in the long term. The results of the research are of great significance to the environmental impact assessment system of the world, especially in countries with similar economic systems, which are facing a trade-off between economic growth and environmental sustainability.

    Li M, Wang X, Wang Z, Maqbool B, Hussain A, Khan WA
    Int J Environ Res Public Health, 2022 Oct 14;19(20).
    PMID: 36293848 DOI: 10.3390/ijerph192013273
    With increasing environmental regulation (ER), the requirements for green technology innovation (GTI) in enterprises are also rising. However, there are relatively few systematic summaries of the themes of ER-affecting GTI. Adopting the method of bibliometrics and visual analysis, this research discusses the status of research and development trends of ER-affecting GTI and summarizes the research in this field. The paper takes 738 papers from 2001 to 2021 in the core database of Web of Science as the research sample. Based on CiteSpace, this paper makes a visual analysis of the number of published papers, institutions, authors, keywords, countries (regions) and journals. The study found that to some extent, favorable collaboration between authors and institutions in this field needs to be strengthened. Research hotspots in this field include innovation, technology, performance, policy and environmental regulation. Renewable energy consumption, the pollution haven hypothesis, sustainable development, carbon dioxide emission, energy technology and environmental Kuznets curve are the current research frontiers in this field. In terms of the number of published papers, research in this field has been conducted in a national (regional) layout with China as the core force, and Italy, America, Britain, Germany and other European countries as important forces. This field covers three main research areas: enterprise performance, policy instruments and research methods, going through the start-up phase (2001-2011), the growth phase (2012-2018) and the development phase (2019-2021). Future research can further incorporate the digital economy and synergy of multiple environmental regulation policies into this field, which will continuously enrich the theoretical research system in this field. The content, methods and conclusions of research in this field are becoming increasingly diverse.

  16. Fulltext Corporate Sustainability Development Strategy and Corporate Environmental Governance-The Moderating Role of Corporate Environmental Investments
    Ao X, Ong TS, Teh BH
    Int J Environ Res Public Health, 2023 Mar 03;20(5).
    PMID: 36901536 DOI: 10.3390/ijerph20054528
    Environmental degradation and ecological devastation have become widespread global concerns in recent years as a result of the expansion of the international economy. China's rapid economic development has been accompanied by a sloppy economic growth model that has damaged the local ecological environment. The Chinese government intends to improve the ecological environment by the end of 2020 in an effort to direct and improve these environmental issues. The strictest environmental laws became effective in 2015. In light of this, this research uses panel data analysis to examine the environmental strategy and environmental governance of Chinese corporations. This article analyses 14,512 samples of listed mainland Chinese enterprises from 2015 to 2020. This research investigates the connection between Corporate Sustainability Development Strategy and Corporate Environmental Governance, as well as the moderating effect of Corporate Environmental Investments.

  17. Fulltext Microplastics Pollution as an Invisible Potential Threat to Food Safety and Security, Policy Challenges and the Way Forward
    Usman S, Abdull Razis AF, Shaari K, Amal MNA, Saad MZ, Mat Isa N, et al.
    Int J Environ Res Public Health, 2020 Dec 21;17(24).
    PMID: 33371479 DOI: 10.3390/ijerph17249591
    Technological advances, coupled with increasing demands by consumers, have led to a drastic increase in plastic production. After serving their purposes, these plastics reach our water bodies as their destination and become ingested by aquatic organisms. This ubiquitous phenomenon has exposed humans to microplastics mostly through the consumption of sea food. This has led the World Health Organization (WHO) to make an urgent call for the assessment of environmental pollution due to microplastics and its effect on human health. This review summarizes studies between 1999 and 2020 in relation to microplastics in aquatic ecosystems and human food products, their potential toxic effects as elicited in animal studies, and policies on their use and disposal. There is a paucity of information on the toxicity mechanisms of microplastics in animal studies, and despite their documented presence in food products, no policy has been in place so far, to monitor and regulates microplastics in commercial foods meant for human consumption. Although there are policies and regulations with respect to plastics, these are only in a few countries and in most instances are not fully implemented due to socioeconomic reasons, so they do not address the problem across the entire life cycle of plastics from production to disposal. More animal research to elucidate pathways and early biomarkers of microplastic toxicity that can easily be detected in humans is needed. This is to create awareness and influence policies that will address this neglected threat to food safety and security.

  18. Fulltext An integrated methodology for establishing industrial effluent limits in developing countries: Iran as a case study
    Mahjouri M, Ishak MB, Torabian A, Manaf LA, Halimoon N
    J Environ Health Sci Eng, 2018 Dec;16(2):181-192.
    PMID: 30728990 DOI: 10.1007/s40201-018-0306-6
    Background: Environmental policies should be developed in a contextual decision-making process regarding local environmental concerns emphasizing the economic, technical, social and institutional considerations. Establishing emission limit levels, especially in the industrial sector, is one of the most problematic environmental issues in developing countries, for which it is essential to include several criteria that reflect their country-specific constraints and capacities. Since Best Available Technology (BAT) is acknowledged to be the reference element for sustainable development and a basis for Emissions Limit Values (ELVs), the objective of this study is to present a reliable methodology for establishing ELVs thresholds with an emphasis on the BAT concept for national regulation at the sector level.

    Methods: A hybrid fuzzy multiple-criteria decision-making (FMCDM) process, consisting of the Analytic Hierarchy Process (AHP) and fuzzy Technique for Order of Preference by Similarity to Ideal Solution (fuzzy TOPSIS) method, is structured to aggregate the different criteria and rank different ELV alternatives in this complicated evaluation. In order to use the most profound knowledge and judgment of a professional expert team, this qualitative assessment highlights the importance of supportive information.

    Results: The results obtained indicate that experts have considered the country-specific information as a reliable reference in their decisions. Among different key evaluation criteria in effluent standard setting, the highest experts' priority is "Environmental protection". For both the conventional and toxic pollutants, the influence of all other criteria namely "Economic feasibility", "Technology viability" and "Institutional capacity", as constraining criteria in developing countries, have not reduced the responsibility towards the environmental objectives. In ELVs ranking, experts have made their decisions with respect to the specific characteristics of each pollutant and the existing capacities and constraints of the country, without emphasizing on any specific reference.

    Conclusions: This systematic and transparent approach has resulted in defensible country-specific ELVs for the Iron and Steel industry, which can be developed for other sectors. As the main conclusion, this paper demonstrates that FMCDM is a robust tool for this comprehensive assessment especially regarding the data availability limitations in developing countries.

  19. Environmental management for dredging sediments - the requirement of developing nations
    Manap N, Voulvoulis N
    J Environ Manage, 2015 Jan 1;147:338-48.
    PMID: 25304520 DOI: 10.1016/j.jenvman.2014.09.024
    Scientific research has characterized the effects of dredging, an underwater excavation process for navigational purposes or material extraction, and has shown its association with a number of chemical, physical and biological impacts. Due to this, much environmental management has been applied in the dredging industry in order to manage its detrimental effects. However, developing nations may have different approaches towards their dredging environmental management to compare to their companions with higher economic strength. Moreover, scientific evidence to make an informed decision is often lacking, hence affecting the number of research executed at these nations, limiting their efforts to preserve the environment. This paper reviews the dredging environmental impacts and its two important factors, dredging technology and sediment characteristic, that determine the magnitude of impacts through literature review, and discusses the need for a more integrated dredging environmental management to be developed for developing nations.

  20. Estimating the demand for drop-off recycling sites: a random utility travel cost approach
    Sidique SF, Lupi F, Joshi SV
    J Environ Manage, 2013 Sep 30;127:339-46.
    PMID: 23810167 DOI: 10.1016/j.jenvman.2013.05.001
    Drop-off recycling is one of the most widely adopted recycling programs in the United States. Despite its wide implementation, relatively little literature addresses the demand for drop-off recycling. This study examines the demand for drop-off recycling sites as a function of travel costs and various site characteristics using the random utility model (RUM). The findings of this study indicate that increased travel costs significantly reduce the frequency of visits to drop-off sites implying that the usage pattern of a site is influenced by its location relative to where people live. This study also demonstrates that site specific characteristics such as hours of operation, the number of recyclables accepted, acceptance of commingled recyclables, and acceptance of yard-waste affect the frequency of visits to drop-off sites.
