Development of Waste-to-Energy Projects

Waste-to-energy plants contribute substantially to achieve the goal of a reliable, sustainable and efficient disposal of waste. Recovery of energy and valuable material is an additional benefit. Before starting the technical elaboration, the non-technical questions have to be answered. They are strongly dependent on local boundary conditions. For the financial aspects some general hints are given as well as rules of thumbs. The technical evaluation bases on system analysis and comparison of operational, design, energetic and environmental criteria.

Goals of waste disposal

Extensive and sustainable environmental protection comprises also that the disposal of domestic and industrial waste is achieved in an economic way and that energetic and material resources are recovered as far as possible and reasonable. The non useable residuals produced by the corresponding treatment processes must be stabilized physically and chemically before they are delivered to landfill.

Domestic waste and a considerable part of industrial waste have a high content of organic material. This upgrades the waste to a fuel resource. The combustion of this fuel resource leads to:

• elimination of organic material,
• production of energy,
• reduction of the waste volume,
• simplification of the recovery process of valuable material contained in the residuals from incineration.

Consequently, this process recovers energy and valuable material and produces inert residuals.

Challenges of Mixed Plastics Recovery from MSW Sources in the United Kingdom
© TK Verlag - Fachverlag für Kreislaufwirtschaft (10/2012)
Part of the integrated waste management approach in the United Kingdom is a mechanical pre-treatment of MSW prior to either EfW (Energy from Waste) or AD (Anaerobic Digestion). As a consequence of the pre-treatment some unwanted material is being separated form the primary target material, and in most cases this material contains some valuable sub grades. One of these sub grades is mixed plastic. The amount and quality of recoverable mixed plastics within MSW depends firstly on the collection and transfer and storage scheme prior to the mechanical pre-treamtent and secondly on the consumer and education from the Local Authority who is ultimately responsible for the local or regional waste management strategy and education.

Plastic Waste Recovery in Spain - Overview of the Market and Applied Technologies
© TK Verlag - Fachverlag für Kreislaufwirtschaft (10/2012)
Plastic consumption in different Spanish industrial sectors was 2.840.000 tonnes in 2010 and generated approxomately 2.206.000 tonnes of plastic waste in 2010. About 23% of this waste was recycled and 17% recovered, being landfilled about 60% [2].

The real control over the success rate for building new EfW plants is not how well we communicate the technology to hosting communities, but their perception of the risk from that technology.
