THE INTERNATIONAL ENERGY AGENCY'S (IEA) WORK IN HARMONISING SAMPLING AND ANALYTICAL PROTOCOLS RELATED TO MUNICIPAL SOLID WASTE (MSW) CONVERSION TO ENERGY

摘要

Legislation relating to the composition of waste and the end products from energy from waste processes is becoming increasingly strict, therefore appropriate sampling procedures need to be available to perform the analyses accurately. It is also important to be able to compare methods used and results obtained from analytical procedures carried out in different countries. Efforts are focused in three areas: Household waste: A considerable body of information has been compiled on methods used to produce compositional information on household waste. This has been added to by literature searches and from countries not participating directly in the work of the activity. The data collated has been used to review protocols being used for the sampling and analysis of household waste. Landfill gas: This work has focused on methods used to determine the concentration of trace organic compounds present in landfill gas. Concerns about such emissions focus on their potential contributions to: 1. human toxicity 2. environmental impacts (e.g. odour and global pollution events) 3. corrosion in gas utilisation systems 4. the composition of emissions from flares, engines, and turbines The methods used vary considerably, often focusing priority pollutants. Studies investigating such emissions are being carried out world-wide. Emission monitoring at MSW combustion facilities: New information concerning the potential application of advanced emissions monitoring techniques at coal and MSW combustion facilities has been collated. This is currently being incorporated into a new document which will update the 1991 IEA technology report "Review of Emissions and Performance Monitoring of MSW Incinerators".
