The Evaluation System

Improving the understanding of the stabilization process is of great significance to guide the sustainable development of municipal solid waste (MSW) landfills. An evaluation system of the stabilization process of MSW landfills has been established. The indices of the evaluation system involve the degradation degree of MSW, the release of landfill gas production potential, and the settlement of landfills. Based on the biochemical-consolidation-solute migration coupled model, an evaluation method of the MSW landfill stabilization process is proposed by combining field tests with numerical simulation. The stabilization process of the Jiangcungou landfill in China is investigated by using the proposed method. The analyzed results show that the stabilization process of high kitchen waste content landfills can be divided into three stages, which is different from the stabilization process of landfills in developed countries. For the Jiangcungou landfill, the ratio of cellulose to lignin in MSW decreases rapidly during the fast degradation stage when obvious settlement occurs. During the slow degradation stage, the hydrolysis rate is slow and settlement develops slowly. When the landfill reaches the stabilization stage, the ratio of cellulose to lignin of MSW changes very slowly; most of the landfill gas potential has been released; the settlement stabilization is completed basically. The change processes of the three evaluation indices are different, of which the degradation stabilization index is the main one. According to the findings above, leachate recirculation is recommended to adjust the degradation environment in the landfill, which can be helpful to avoid acidification at the fast degradation stage. Temporary cover is suggested to improve landfill gas collection efficiency at the beginning of the stable methanogenic stage. The landfill site closure should be operated when the settlement rate is low.

Collection efficiency is a key indicator for the design and evaluation of municipal solid waste (MSW) landfill gas (LFG) collection and utilization system. Although most Chinese sanitary landfills have been equipped with LFG collection systems, there are no accurate data on collection efficiencies, lack of which always result in huge loss of LFG or investment. The fates of methane generated in a landfill include collection through LFG pipes, fugitive emission from the surface, and oxidation by methanotrophs. Field campaigns for measuring methane emission and oxidation were conducted at one landfill located in Beijing. Methane samples were collected by means of static flux chambers. The measurements were carried out at soil covered road and operating and slope surfaces. Two methods, i.e. landGEM model based and field measurement based estimation were used for calculating the collection efficiency in this research. The methane emission amount were 262.1 and 53222.4 m3 in July 2013 for the working and slope surfaces, respectively. The collection efficiency was 94.3% according to field measurement. Calculated with the LandGEM model, the collection efficiencies for 2011 and 2012 were 48.5 and 47.7% (k=0.09 yr-1) and 20.9 and 22.2% (k=0.3 yr-1), respectively. The estimation based on field measurement was more credible than the other, although the lateral migration and the storage insitu were naglected. The model method did not perform well probably due to the inapplicability of the landGEM model on this landfill, where the MSW was packed into small-subcells, and inaccurate parameter, k.

Energy recovery from municipal solid waste is one of the means to attain sustainable development. Multiple factors involving several location specific situations, both measurable and intangible, makes decision making for technology selection very difficult. In this paper, a multi criterion evaluation system for municipal solid waste treatment strategies is established on the basis of specific, measurable, attainable, relevant and trackable situations, to prove the effectiveness of this method. From among various alternatives, three prominent strategies, namely, incineration, anaerobic digestion and composting are considered for the evaluation. Exhaustive data collection is done from conducting field studies, as well as from published data. Three types of communities are evaluated by this technique, namely, typical cities in developed countries, ‘A’ grade cities in India and ‘B’ grade cities in India. The purpose of the study is to evaluate the effect of community specific situations on the right choice of waste disposal method using a technique for order of preference by similarity to ideal solution (TOPSIS) approach, where weights of criteria are determined by means of entropy weight method. The case study shows that the proposed evaluation results are reliable, which are more coincident with the reality, since the most relevant factors for selection have been used backed by exhaustive field data collection. Policy makers gain from the outcome of this study by guiding them through technology selection. So, the adopted approach should be promoted widely in the evaluation of waste treatment strategies, to realize sustainable development.

Separate collection of municipal solid waste (MSW) is mandatory in Italy, and an increasingly higher standard of efficiency is applied; in fact, the target value set by regulation is 65%. In the last 20 years, separate collection efficiency increased from 9.4% with 80% national MSW landfilled, and only one region was over 25% separate collection to 58.1% with 22% national MSW landfilled and 12 of 20 regions over 55% separate collection. However, significant differences are present in the three Italian macro regions (North, Center and South). This paper analyzes the composition of waste carried in most Italian regions to evaluate the effect of separate collection on the composition of mixed municipal solid waste (unsorted). Moreover, a regression analysis on the same data allows to assess this latter as a function of separate collection efficiency.
