New findings on the generation of waste and emissions, and a modified cleaner production assessment approach-illustrated by leather production

New findings on the causes of waste and emissions, which were obtained from analysing numerous material streams in various sectors of industry, are presented in this article. It describes the implications of these findings for the vision of clean production, for formulating environmental policy concerning cleaner production targets, for the opportunities to assess to what extent the cleaner production targets have been met, and for the cleaner production assessment. A modified cleaner production assessment approach is presented, and illustrated using leather production as an example. The consequent implications for the diffusion of cleaner production are discussed.     

水泥负载TiO2光催化降解染料水溶液的研究

研究了以ＴｉＯ２为催化剂，且将ＴｉＯ２涂布在模拟工业水处理浅池的水泥质池底表面，以直管高压汞灯为光源，对有机染料酸性玫瑰红Ｂ和晒化绿Ｂ进行光催化降解的可行性。结果表明，在实验条件下，本系统对以上染料有显著的光降解作用，浓度为２５ｍｇ／Ｌ的上述二种染料溶液，经３０ｍｉｎ光照，其降解率分别达８８．２％，此外，还探讨了染料浓度，染料体积、染料溶液ＰＨ值等因素对光降解的影响。

Phosphorus recovery from municipal and fertilizer wastewater: China's potential and perspective

Phosphorus (P) is a limited resource, which can neither be synthesized nor substituted in its essential functions as nutrient. Currently explored and economically feasible global reserves may be depleted within generations. China is the largest phosphate fertilizer producing and consuming country in the world. China''s municipal wastewater contains up to 293,163 Mg year of phosphorus, which equals approximately 5.5% of the chemical fertilizer phosphorus consumed in China. Phosphorus in wastewater can be seen not only as a source of pollution to be reduced, but also as a limited resource to be recovered. Based upon existing phosphorus-recovery technologies and the current wastewater infrastructure in China, three options for phosphorus recovery from sewage sludge, sludge ash and the fertilizer industry were analyzed according to the specific conditions in China.
