    Economic and environmental implications of policy instruments for the circular economy: A case study for postconsumer polyethylene film recycling in Europe
    (2024) Larrain, Macarena; Billen, Pieter; Cifuentes, Luis; Van Passel, Steven
    The objective of this paper is to examine the recycling rates for mechanical and thermochemical recycling of postconsumer polyethylene flexible packaging after the implementation of different policy instruments. The study uses a supply chain equilibrium model that incorporates market data and techno-economic assessments to simulate market equilibrium. It combines this with a life cycle assessment to explore the environmental implications of implementing different policy instruments. The results show that instruments that do not target a specific technology are more likely to increase thermochemical recycling than mechanical recycling. Furthermore, a higher recycling rate is not equivalent to a better environmental outcome. An increased collection target that ensures a supply of plastic waste would increase the overall recycling rates the most. A recycled content standard for mechanical recycling would lead to the highest increase in mechanical recycling, with top results for environmental indicators, but low results for economic indicators.

    Environmental attitudes and behaviors of college students: a case study conducted at a chilean university
    (2013) Heyl, Marianne; Moyano Diaz, Emilio; Cifuentes, Luis
    Encouraging the adoption of a pro-environmental behavior is critical in order to reduce the environmental impacts and to move toward a more sustainable future. Higher education plays an important role in training professionals who have an important role in protecting the environment in the future. The aim of this study is to identify whether there are significant differences between college students depending on their diploma of specialization, related to the environment or not, the year in which they are studying and gender. The sample consisted of 383 engineering students in first, third and sixth year, with two instruments designed to measure environmental attitudes and behaviors. Significant differences were found between students pursuing diplomas related to the environment and those who are not. Otherwise, no significant differences were observed between students enrolled in different levels. Perceived effort, positive environmental attitude or perceived positive consequents predict the frequency of pro-environmental behaviors in students, the former (perceived effort, negative) being the most influential variable.

    Meeting report: Threats to human health and environmental Sustainability in the pacific basin
    (US DEPT HEALTH HUMAN SCIENCES PUBLIC HEALTH SCIENCE, 2007) Arnold, Robert G.; Carpenter, David O.; Kirk, Donald; Koh, David; Armour, Margaret Ann; Cebrian, Mariano; Cifuentes, Luis; Khwaja, Mahmood; Ling, Bo; Makalinao, Irma; Paz y Mino, Cesar; Peralta, Genandrialine; Prasad, Rajendra; Singh, Kirpal; Sly, Peter; Tohyama, Chiharu; Woodward, Alistair; Zheng, Baoshan; Maiden, Todd
    The coastal zone of the Pacific Rim is home for about one-third of the world's population. Disproportionate growth of Far Eastern economies has produced a disproportionate share of related environmental difficulties. As the region searches for acceptable compromises between growth and environmental quality, its influence on global environmental health is certain to increase. Consequences of global environmental change such as habitat alteration, storms, and sea-level rise will be particularly acute among Pacific Rim nations. Adverse health effects from arsenic exposure in Pacific Rim nations have been used to justify drinking water standards in the United States and elsewhere. As global manufacturing in the Pacific Rim increases, the centroid of global air quality and waste management issues will shift further toward Far Eastern nations. The Eleventh International Conference of the Pacific Basin Consortium (PBC) was held in September 2005 in Honolulu, Hawaii. The purpose of the conference was to bring together individuals to discuss regional challenges to sustainable growth. The historic emphasis of the conference on hazardous wastes in relation to human health makes the PBC an ideal forum for discussing technical aspects of sustainable economic growth in the Pacific region. That role is reflected in the 2005 PBC conference themes, which included management of arsenic in potable waters, air quality, climate change, pesticides, mercury, and electronics industry waste-each with emphasis on relationships to human health. Arsenic management exemplifies the manner in which the PBC can focus interdisciplinary discussion in a single technical area. The conference program provided talks on arsenic toxicology, treatment technologies, management of arsenic-bearing residuals from water treatment, and the probable societal costs and benefits of arsenic management.
