SUSTAINABLE RECYCLING OF SOLID WASTES VIA IN-PROCESS SEPARATION

扫码查看
Recycling of solid wastes plays an important role in environmental protection。 However, solid wastes are often contaminated with some undesired components so that many of these solid wastes are hardly economically recycled。 Therefore, effective and efficient separation of undesired components from solid wastes becomes a crucial step for sustainable recycling of the solid wastes。 There exist three general strategies of separation of undesired components from solid wastes: before-process separation, post-process separation and in-process separation。 In this paper, different separation strategies are discussed in terms of energy requirement and availability, implementation complexity and additional need for environmental protection。 It is concluded that of all separation strategies, in-process separation has the least energy requirement, the least implementation complexity and the minimum need for additional environmental protection。
