A new guide to help collegiate foodservice operations across the globe contribute to a better world is now available from the National Association of College & University Food Services (NACUFS). The NACUFS Collegiate Foodservice Sustainability Guide© helps collegiate foodservice operators implement or enhance a sustainability program, whether they are in the early stages of building a comprehensive program or already have a mature program underway. The Guide provides an overview of 10 key sustainability issues, from animal welfare to sustainable seafood, and implementation of best practices. Further, a Self-Assessment Tool is provided to measure and assess current efforts and track improvements year-over-year.

Cumulative photovoltaic (PV) power installed in 2016 was equal to 305 GW. Five countries (China, Japan, Germany, the USA, and Italy) shared about 70% of the global power. End-of-life (EoL) management of waste PV modules requires alternative strategies than landfill, and recycling is a valid option. Technological solutions are already available in the market and environmental benefits are highlighted by the literature, while economic advantages are not well defined. The aim of this paper is investigating the financial feasibility of crystalline silicon (Si) PV module-recycling processes. Two well-known indicators are proposed for a reference 2000 tons plant: net present value (NPV) and discounted payback period (DPBT). NPV/size is equal to −0.84 €/kg in a baseline scenario. Furthermore, a sensitivity analysis is conducted, in order to improve the solidity of the obtained results. NPV/size varies from −1.19 €/kg to −0.50 €/kg. The absence of valuable materials plays a key role, and process costs are the main critical variables.
