Resource Recovery from Waste Using the Input Flexibility of Waste Gasification Technology
© ThomĂ©-Kozmiensky Verlag GmbH (9/2016)
Nowadays, gasification of waste or biomass is becoming the great interest all over the world. Especially, gasification of municipal solid waste (MSW) has been well-researched in Japan. The development of MSW gasification technology was started in the 1970s in Japan because of oil crisis. Several technologies have been researched and developed. The Direct Melting System (DMS), which is the gasification and melting technology developed by Nippon Steel & Sumikin Engineering Co., Ltd., is one of the developed waste gasification technologies in this era. This technology was introduced for commercial use in Kamaishi City, Japan in 1979. As well as this waste technology, other gasification technologies have been developed for commercial use and installed.

Overview of the Pyrolysis and Gasification Processes for Thermal Disposal of Waste
© ThomĂ©-Kozmiensky Verlag GmbH (9/2016)
Thermal treatment of waste started in the 1870s in England with the first waste incineration plants and this technology was in short time adopted by many industrialised countries. Starting in the late 1970s waste incineration was blamed for emission of toxic compounds, in particular of dioxins, and public pressure initiated the decree of more and more stringent air emission standards in all countries which, again, induced significant improvement of the environmental performance of waste incineration.

JFE High-Temperature Gasifying and Direct Melting Furnace System (hereinafter Gasifying and Melting System) was developed to treat any kind of wastes and to contribute to energy and material recovery. Gasifying and Melting System was developed by integrating company’s original technologies for the iron-making blast furnace and fluidized bed for incineration plants, which the company cultivated over many years. The company’s advanced technologies in these two different fields were combined and integrated into the unique Gasifying and Melting System. This system is a proven technology that realizes high performance

Application of Modified NiCrMo Alloy Systems for Boiler Tube Surface Protection in Waste-to-Energy Environments
© ThomĂ©-Kozmiensky Verlag GmbH (9/2016)
Internationally, Waste to Energy and Incineration markets continue to grow in capacity as fossil fueled facilities decline and nuclear generation is curtailed. With this comes a greater need to burn more corrosive materials combust at higher temperatures and extract more energy. The reliability burden that this places on operators of plants is re-opening opportunities for thermal spray solutions as a cost effective solution for boiler tube protection. Where maintenance costs, opportunity costs and access restrictions may preclude alternative in-situ technologies, thermal spray technology may fill a gap in providing new reliable and flexible process and materials technologies for both mid- and long-term protection of water wall and superheater tubes. While historically thermal spray coating solutions have had a spotty record in waste to energy environments, advances in both process and materials technology specifically for WTE environments is such that coating performance now approaches the performance of high alloy wrought materials. This is verified through accurate laboratory modeling and scale tests and trials conducted by OEM’s and plants.

The cement industry plays a pivotal role in meeting society’s needs for housing and infrastructure. Cement is one of the most important and widely used commodities in the world and is therefore a key ingredient of economic development. Current world production of cement is well above 4,500 million tons per year and growing.

Enhancing of the Energy Efficiency of an Existing Waste Incineration Plant by Retrofitting with a District Heating Network
© ThomĂ©-Kozmiensky Verlag GmbH (9/2016)
The German Cycle Economy Act (Kreislaufwirtschaftsgesetz KrWG) and discussions on the turn of local energy policies led to intensive examination of options for optimising utilisation of heat produced by the waste incineration plant (MKW) in Weißenhorn. This has been carried out by the waste management firm(Abfallwirtschaftsbetrieb – AWB) of the district of Neu-Ulm over a long period of time. This was also prompted by knowledge that utilisation of already generated energy in the form of combined heat and power generation (CHP) is one of the most efficient ways of achieving climate protection targets. This results from considering which courses of action are available for climate protection.

New Waste-to-Energy Facility Energy Works Hull, United Kingdom
© ThomĂ©-Kozmiensky Verlag GmbH (9/2016)
Energy Works Hull (the Project) is a milestone project for the UK’s waste and renewable energy sector. It will be one of the largest gasification facilities receiving MSW in the UK, indeed in Europe. It is one of the first advanced conversion technology Projects to receive its renewable electricity subsidies through a Contract for Difference, the mechanism by which the UK Government determined to move from Renewable Obligation Certificates following its Electricity Market Reform process. It also plays a significant part of the urban regeneration of the City of Hull. The level of community engagement and benefit has resulted in the project receiving a GBP19.9M grant from the European Union’s Regional Development Fund.

The artefacts map for waste treatment plants - working optimization for laboratories with fermentation units
© European Compost Network ECN e.V. (6/2014)
The optimization of workflows ensures efficiency of processes. Especially in waste treatment for the warranty of same boundary conditions coordinated work processes are required. This includes the use of measurement technology, the use of evaluation methods and the exchange of knowledge between stakeholders. The artifacts map documented object-specific information of individual objects, connecting footpath and interaction patterns on the job. Therefore, different test people and their handling with artifacts should be observed in their everyday work.

In the beginning of 21th century there was a huge dynamic change in the practice of the solid waste management. Earlier the collected solid municipal waste went directly to the landfills without any treatment. Nowadays, we have different technologies to ensure the high recycling ratio in the solid waste treatment.
