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.
Cement is the key ingredient of concrete, which is used to build offices, factories, homes, schools, hospitals and roads, as well as our underground water and drainage pipes, bricks and blocks, and the mortar that bonds them together. None of these things could be built without cement. There is currently no other material that can replace cement or concrete in terms of effectiveness, price and performance for most purposes. Not surprisingly there is a strong link between economic growth and the increase of
cement production per capita.

The Added Value of the Balance Method for Waste-to-Energy Operators and National Authorities
© Thomé-Kozmiensky Verlag GmbH (9/2016)
Different directives of the European Union may require operators of Waste to Energy WTE plants to monitor the composition of their waste feed with respect to the Content of biomass and fossil organic matter. The mass fractions of both materials are not only of relevance for the amount of fossil and thus climate relevant CO2 emissions of the plant, but also for the ratio of renewable energy generated, as biomass in wastes is considered as renewable energy source.
Complex Approach towards the Assessment of Waste-to-Energy Plants’ Future Potential

There is a fierce debate ongoing about future recycling targets for municipal solid waste (MSW) at the European level. The old linear concept of waste management is being changed into a circular economy. Since the separation yield and post-recycling MSW (later on residual solid waste, RSW) production have an opposite relationship, assuming the constant production of particular components (paper, plastics etc.), lower RSW rates are also expected. This is having a negative effect on Waste-to-energy (WtE); especially in terms of its future optimum capacity in particular countries.
Overview of the Pyrolysis and Gasification Processes for Thermal Disposal of Waste

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.
Resource Recovery from Waste Using the Input Flexibility of Waste Gasification Technology

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.
New Waste-to-Energy Facility Energy Works Hull, United Kingdom

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.
