Waste Characterisation

This paper investigates the feasibility of using municipal solid waste (MSW) as biomass substrates for bioethanol production. MSW are categorised into three types: paper and card, kitchen organics, and green organics. MSW data are collected from UK Department of Environment, food and rural affairs (DEFRA). Characterisations of cellulose, hemicellulose, and lignin contents have shown that MSW has high potential as biomass source. Experimental work on waste characterisation and MSW-to-ethanol conversion has been carried out in laboratory. The experimental results have shown that more than 85% of the cellulose from the waste can be converted to glucose which can be easily fermented to ethanol production. This MSW-to-ethanol process provides an alternative solution for both biomass resources for cost reduction and preventing organic fraction of municipal solid waste going into landfill.Projected estimates of waste to ethanol bases on London (UK) as a case study are made. Recommendation on both sustainable waste management and biofuel production are developed based on the result findings.

As world population and industrialization increase, the consequence has been an increase in waste generation. In an attempt to curb this increase and recover value from the waste streams, the European Union (EU) and UK have introduced a wide range of legislation, focusing to a large extent on the biodegradable component of municipal solid waste (MSW). Although by no means the largest component of the total waste generated, it is a significant contributor to greenhouse gas emissions if left unmanaged. Strict targets for its diversion from landfill have been set and these will become increasingly challenging between 2010 and 2020. Despite the raft of legislation, this article demonstrates that the definitions and properties of MSW and its management strategies can vary considerably across the EU. Variations also exist across the UK, making it difficult to compare one region and its management strategies to another. The generic role of the materials recovery facility (MRF) is seen as crucial by the authors and this article examines its place across the management spectrum. Data are presented to demonstrate the effectiveness of one such MRF operating in both ‘clean’ and ‘dirty’ modes. Its ability to recover product streams such as ferrous metal, aluminium, plastic containers, paper, and card is reported along with a brief economic assessment.

The performances of an integrated system based on mechanical biological treatment and bioreactor landfill with leachate recirculation for managing the mixed municipal solid waste generated in a given Italian district were investigated. In the mechanical biological treatment the municipal solid waste was mechanically sorted into two main streams: a dry and a mechanically sorted organic fraction consisting of 45,000 tonnes year−1. After being sorted the mechanically sorted organic fraction was aerobically pretreated before being disposed of in the 450,000 m3 bioreactor landfill. Experimental runs showed that an aerobic pretreatment period ranging from 15 to 30 days was able to maximize the methane generated by the mechanically sorted organic fraction once landfilled up to 10 Nm3 tonne−1. The aerobic pretreatment leads to a significant volatile solids reduction in the first 30 days, after which the volatile solids concentration remained quite constant. Similarly the potential dynamic respirometer index was significantly reduced in the first 15 days of the aerobic pretreatment decreasing from about 5,000 to about 3,500 mgO2kgVS−1h−1. The whole amount of electrical energy producible by the landfill ranged from 18.5 kWh tonne−1 to 21 kWh tonne−1, depending on the strategies adopted for the activation in bioreactor mode of each landfill cell by the leachate recirculation.
