About

Organics has been in the waste-as-a-resource business for over thirty years. During this time the company has provided over five hundred projects around the world with equipment to make beneficial use of a wide range of waste types. It has been a logical extension of Organics’ scope to develop Refuse Derived Fuel (RDF) equipment and facilities.

RDF production is an essential and integral part of a modern society’s waste management options. By means of a range of transformative processes, waste can be converted into a useful product which can replace high-grade fossil fuels. Subject to form, moisture content and calorific value, RDF can be used in a range of industrial processes from fluidised bed combustion, to cement kilns and in RDF-fired power generation facilities.

RDF

Refuse-derived fuel (RDF) is a fuel produced from various types of waste such as municipal solid waste (MSW), industrial waste or commercial waste.

RDF 2

Materials such as glass and metals are removed during the treatment processing since they are non-combustible. The metal is removed using a magnet and the glass using mechanical screening. After that, an air knife is used to separate the light materials from the heavy ones. The light materials have higher calorific value and they create the final RDF. Continue reading “RDF 2”

RDF 3

RDF can be used in a variety of ways to produce electricity. It can be used alongside traditional sources of fuel in coal power plants. In Europe RDF can be used in the cement kiln industry, where the strict standards of the Waste Incineration Directive are met. RDF can also be fed into plasma arc gasification modules & pyrolysis plants. Where the RDF is capable of being combusted cleanly or in compliance with the Kyoto Protocol, RDF can provide a funding source where unused carbon credits are sold on the open market via a carbon exchange.

The European markets for the production of RDF have been grown fast due to e.g. the European landfill directive, or landfill taxes e.g. in UK and Ireland. Refuse derived fuel (RDF) exports from the UK to Europe and beyond reached 3.3 million tonnes in 2015, representing a near-500,000 tonnes increase on the previous year.

RDF 4

According to ASTM standards E856-83 (2006), RDF can be classified into 7 categories. The material presented here is defined as “Type 4”. Combustible wastes processed into powder form, 95 % by weight passes through a 10 mesh screen (2.0 mm square), namely Powder RDF. Parameters may be tailored to specific requirements.

This makes RDF4 suitable for direct firing in industrial forced air burners.
