中国农村生活垃圾管理模式探讨——三级分化有效治理农村生活垃圾

针对农村生活垃圾及其处理的特点,为降低难度更有效地处理好农村生活垃圾,提出了对农村生活垃圾进行三次分化,用不同措施分别处理不同特点的农村生活垃圾,从而使其处理难度和费用最小化.首先分类收集作为基础,按不同类别对农村生活垃圾进行收集;其次,分离出产生源集中、规模较大和成分较单一的乡镇街道、畜禽养殖场和乡村企业等三类农村垃圾进行专门管理;最后依据有机垃圾的不同特点,分成农业主导型、非农业主导型和城郊型三类区城进行专门的垃圾处理.

Reasons for non-participation in a kerbside recycling scheme

In this article potential barriers to recycling are explored within a UK community of approximately 8000 households that are piloting a kerbside paper recycling scheme. All 1690 non-users of the scheme were surveyed for their decisions not to participate. A 43% response rate was generated from the survey and the reasons given by householders were coded into 12 categories. The main reasons for non-participation included insufficient paper and lack of space in which to locate the recycling bin. 62% of the non-participants reported that they were recycling paper using other facilities such as local bring schemes and charity collections. Strategies to increase participation in the kerbside scheme are suggested.

Selective collection as a pretreatment for indirect solid recovered fuel generation

Effective selective collection (SC) has been increasing in many countries of the European Union. As a consequence the composition of residual municipal solid waste (RMSW) is changing not only because of economic development, but also due to the collection system. The input of RMSW treatment plants is thus not homogeneous. This paper analyses two case studies involving a total of five SC scenarios and their impact on the generation of solid recovered fuel (SRF) with/without bio-drying, post-treatment and packaging take back programs (TBPs). These case studies are based on two types of SC: kerbside and drop-off. The latest regulation on SRF classification is taken into account: energy content, Cl and Hg concentrations are assessed and discussed. The role of the respirometric index (RI) is also analyzed. Results show that when SC is highly efficient RMSW can be classified directly as SRF, but only if the introduction of RI does not set stringent respirometric targets. The role of packaging TBPs is important as the residual waste remaining after the packaging has been processed, can be valorized increasing the lower heating value (LHV) of the residual RMSW and minimizing the streams that should be landfilled. The source separation of food waste has a significant impact on the suitability of bio-drying: when the SC of food waste is very efficient, its percentage in the RMSW may be too low for effective bio-drying.
