Curbside Recycling: Waste Resource or Waste of Resources?
In this paper, we address the often contentious debate over state and local recycling policy by carefully estimating the social net benefit of curbside recycling. Benefits are estimated using household survey data from over 4,000 households across 40 western U.S. cities. We calibrate household willingness-to-pay for hypothetical bias using an innovative experimental design that contrasts stated...
متن کاملRecycling of Renewable Resources in Extra corporeal Circulation Technology
This project evaluated the cost effectiveness and feasibility for recycling of renewable resources and disposing of non-recyclable materials generated in the perfusion department of an open heart surgery program. Forty-one adult and pediatric open heart cases were randomly assigned to participate as the control or the recycling group. The control group had no separation of materials. In the rec...
متن کاملchemical recycling of polycarbonate waste using conventional heating and microwave assisted method
پلی کربنات یکی از پلاستیکهای مهمی است که به صورت گسترده در تولید لوحهای فشرده، قطعات رایانه، مواد ساختمانی و غیره مورد استفاده قرار می گیرد. این پلیمر بصورت عمده از تراکم مونومر بیس فنولa (bpa) و کربنیل کلرید یا دی متیل کربنات ها بدست می آید. در سالهای اخیر بازیافت شیمیایی پلی کربنات بیشتر مورد توجه بوده است. بازیافت شیمیایی پلی کربنات برای بدست آوردن مواد اولیه آن با روشهای متفاوتی مانند تجزی...
Waste, poverty and recycling
Environmental hazards as a consequence of mass consumption and waste disposal remain largely unconsidered in affluent societies. Resources embodied in waste are not recognized. In Latin America, Asia and Africa, in particular, an extensive informal sector is involved in the collecting and separating of recyclable materials. This widespread activity provides an insight into the resourcefulness o...
