Dissipation and Recycling: What Losses, What Dissipation Impacts, and What Recycling Options?

摘要: This chapter describes the activities in Dissipation and Recycling Node of Global TraPs, a multistakeholder project on sustainable management global phosphorus (P) cycle. Along P supply demand chain, substantial amounts are lost, notably mining, processing, agriculture via soil erosion, food waste, manure, sewage sludge. They not only critical with respect to wasting an essential resource, but also contribute severe environmental impacts such as eutrophication freshwater ecosystems or development dead zones oceans. The covers system from those points where phosphate-containing waste losses have occurred been produced by human excreta, livestock, industries. recycling efforts, identifies knowledge implementation dissemination gaps well questions, outlines potential transdisciplinary case studies. Two pathways toward focus: To major goal therefore must be (1) quantify stocks flows order (2) identify key areas for minimizing realizing opportunities. Several technologies already exist recycle different sources, including sewage, steelmaking slag; however, due various factors lacking economic incentives, insufficient regulations, technical obstacles, missing anticipation unintended impacts, minor part secondary resources has utilized. Minimizing increasing rates reducing triggered dissipation require better understanding social, technological, rationale intrinsic interrelations between nutrient cycling ecosystem stability. A useful approach will develop new social business models integrating innovative technologies, corporate strategies, public policies. That requires intensive collaboration scientific disciplines and, most importantly, among variety stakeholders, industry, farmers, government agencies.
