Applying Mechanical Pre-Treatment and Landfill Mining Approach in Recovering Refuse Derived Fuel (RDF) from Dumpsite Waste: Thailand Case Study
This paper explores the possibilities of using basic mechanical pre-treatment principals band Landfill mining approach to recover the discarded plastics from Nonthaburi solid waste disposal site in Thailand. The excavated wastes from the dumpsite were characterized for their physical composition and chemical characteristics according to their disposal age. The composition of solid waste excavated from the site showed high plastic wastes content (25 to 45%) of total weight.
The waste samples were first manually sorted to remove noticeable inert fractions and metallic components from the plastic wastes. The sorted wastes are then passed through a rotary trommel screen to remove finer particles and soil components. After trommel screening the plastic contents in the treated waste increased up to 83 – 90%. The sorted plastics were then shredded and blended with cassava starch in a proportionate ratio to produce RDF mainly targeted for industrial fuel. These were then formed into briquettes using a screw compactor. The maximum plastic content for an ideal densification of the briquettes were determined. The quality concerns and the characteristics of the fuel produced were in compliance with standards and acceptable for industrial use. This paper also looks into the economic aspects of producing such fuels.

Plastics Recycling and Energy Recovery Activities in Poland – Current Status and Development Prospects –

The waste disposal system in Poland is one of the least advanced in Europe. Despite great efforts over the last 20 years municipal waste landfilling has only reduced from 95 percent in 1991 to 73 percent in 2010. This still means that millions of tonnes of post-consumer waste continue to be landfilled.

Current compost production in Izmir and the utilization of the residues from composting process

Landfilling is the main disposal method to remove organic solid waste in Turkey. Even if the domestic solid waste generally has high water content and it is reach by means of biodegradables, the number of composting facilities is limited and they are mainly located in the cities with high population. However, composting is an advantageous method for the countries having both high amounts of organics in their waste and widespread agricultural activities, such as Turkey. Limited landfilling areas and difficulties to locate new landfills are the effects to aim composting, as well as it is the priority disposal method of Turkish Ministry of Environment and Forestry.

Die Papierindustrie könnte die Kosten für die Verwertung ihrer betrieblichen Abfälle um bis zu 90 Prozent senken und dabei gleichzeitig die Umwelt enorm entlasten. Vorausgesetzt, sie könnte sich darauf verständigen, ihre Reststoff-Ströme branchenübergreifend zu bündeln und in zentralen Anlagen energetisch zu nutzen. Eine Studie für Bayern zeigt, was ein integriertes Verwertungskonzept leisten kann.
