TECHNOLOGY SUPPORT

Technology support

The huge potential of converting waste into useful resources is now well recognized. However, information on technologies which can be used to convert waste into specific materials or energy is rather scattered. Policy makers and decision makers thus find it difficult to identify and assess different technologies and select the ones suited to local conditions.

IETC has developed a series of compendiums of technologies for waste management in general as well as for specific waste streams with a view to provide information on various technology options as well as to assist the policy –makers and technology decision makers in the identification of appropriate technologies with respect to local economic, environmental, social and technical characteristics.

The compendiums refer to technologies in different stages:

  • in commercial use

  • under pilot implementation

  • under laboratory testing.

Additionally IETC has developed a methodology – sustainability assessment of technologies (SAT) – to assist policy makers in the assessment and selection of the appropriate technology under specific local conditions.

Converting Waste Agricultural Biomass into a Resource – Compendium of Technologies, Oct 2009Converting Waste Agricultural Biomass into a Resource – Compendium of Technologies, Oct 2009 (PDF 5.2MB)

Globally, 140 billion metric tons of biomass wastes are generated every year from agriculture equivalent to about 50 billion tons of oil. As raw materials, biomass wastes have attractive potentials for both large-scale industries and community-level enterprises. For efficient and effective conversion, appropriate selection of technologies is one of the vital pre-conditions. This compendium is compiled to assist in the selection process for the technologies. The technologies for different type of waste agricultural biomass and different sizes are also considered. Technologies listed in the Compendium are limited to those that use cellulosic agricultural waste biomass.

Converting Waste Plastics into a Resource – Compendium of Technologies, Dec 2009 Converting Waste Plastics into a Resource – Compendium of Technologies, Dec 2009 (PDF 1.4MB)

Economic growth and the change of consumption and production patterns are resulting in rapid increase in generation of waste plastics in the world. The world’s annual consumption of plastic materials has increased from around 5 million tonnes in the 1950s to nearly 100 million tonnes nowadays. Waste plastics are one of the most promising resources for fuel production; however the effective conversion requires appropriate technologies to be selected according to local economic, environmental, social and technical circumstances. This compendium is compiled to assisst in the selection process. Technologies for conversion of plastics to solid, liquid and gaseous fuels are listed in it.

Sustainable Assessment of Technologies (SAT)Sustainability Assessment of Technologies (SAT)

The methodology of sustainability assessment of technologies (SAT) has been developed to assist decision-makers in selecting appropriate technologies from several options. The methodology is very flexible and can be applied across a wide range – policy level macro decision making to project level micro decision making. The methodology is being tested in different IETC projects and will soon be published.
