Shaft Furnace Type Gasification and Direct Melting System – Technology, Input Flexibility, Operational Characteristics and Emissions –
© TK Verlag - Fachverlag für Kreislaufwirtschaft (12/2015)
Gasification of municipal solid waste has been widely researched all over the world and is recognized as an alternative thermal technology for waste treatment. The Direct Melting System is shaft-furnace type gasification and melting technology for various kinds of wastes. It has more than 40 references and has been operated for 36 years. This gasification technology is employed to treat municipal solid waste, but can also treat various kinds of wastes together and can achieve both the energy and material recovery from waste in one process.

Considering the worldwide number of installations as well as their capacity, the most dominating treatment method for waste is incineration. Currently, 225 million tons of waste are treated in 2,200 facilities.

Advanced Urban Mining: A Summary of the State of the Art of Metal Recovery out of Dry Bottom Ash

The world’s demand for resources will ceaselessly increase in future. This will have a negative impact on availability and price of finite resources. The only way to satisfy the future demand is to minimize the dissipation of the resources during their life-cycle and to close the latter as good as possible. A potential shortage of resources in the future will make the recovery of resources from waste more efficient than their primary production. Another driver towards the minimization of resource dissipation will be the increasingly tighter legislation on environmental protection.

Decentralised Waste Incineration Plant R.Vandhoo in the North of the Maldives - Project Experience, Energy Use and First Operation Results -

Environmental pressures in the Maldives raised from the fragile geography of the country coupled with rising population densities, increased tourism and changing consumption patterns. The country faces growing problems with solid waste management and pollution from sewage and other effluents emanating from urban settlements, hotels, fish-processing plants, ships and other sources. The quantities of solid waste generated exceed disposal and treatment capacity. Most wastes are dumped onto the island foreshore and burnet at low combustion temperatures. Uncontrolled waste disposal and floating debris at tourist resorts is the most visible threat to the country´s reputation as a pristine high-end tourist destination.

Flue Gas Treatment – State of the Art
© TK Verlag - Fachverlag für Kreislaufwirtschaft (12/2015)
For the removal of air pollutants from the flue gas, a flue gas treatment system is required downstream the boiler. Such treatment systems consist of a system of cleaning processes for the reduction of particulate, vapour and gaseous substances in the flue gas.

Possibilities of Development of Municipal Waste Recycling and Incineration in Poland
© TK Verlag - Fachverlag für Kreislaufwirtschaft (12/2015)
One of the basic rules in the field of waste management is the use of processes which are located as high as possible in the waste hierarchy, while taking into consideration the life cycle thinking. This also applies to municipal waste management. Waste prevention is at the top of the hierarchy. This is followed by: preparation for reuse, recycling and other recovery processes, including thermal treatment (incineration) of waste with energy recovery. The disposal of waste, which includes, among others, landfilling, is at the bottom of the hierarchy. Thus, the objective is to move up the hierarchy, which means moving away from waste disposal towards waste recovery.

High-Temperature Gasifying and Direct Melting System for Energy and Material Recovery from any Type of Wastes

JFE High-Temperature Gasifying and Direct Melting Furnace System was developed by integrating our original technologies for the ironmaking blast furnace and fluidized bed for incineration plants, which the company cultivated over many years.

Situation and Waste Management Strategy of the Czech Republic and Experience in Planning, Construction and Operation of WtE and SRF Plants
© TK Verlag - Fachverlag für Kreislaufwirtschaft (12/2015)
Waste utilization has the potential of savings in using fossil fuels. In the Czech Republic, three incinerators of municipal waste are operating currently, there are many projects for implementation of others; unfortunately, they usually fail to succeed due to the economic evaluation. Support for the construction of new facilities for thermal treatment of waste is practically non-existent. Apparently, this could be solved through a number of alternative approaches – combined combustion, processing of sorted waste; however, a conceptual solution is still missing. The article aims to present the current situation and potential for the future.
