The Use of Renewable and Alternative Fuel in the Heavy Clay Industry

Abstract The heavy clay industry brick is in many countries a very important economic factor with far reaching financial and environmental impacts. In the industrialized countries the use of alternative fuels in the heavy clay industry is rather limited.The European brick industries common current research activity is mainly focused on synthgas from waste streams. In-house research activity by single brick companies does, at least in Europe, not take place at the moment. The situation in the developing and industrializing countries is far different: The use of alternative,fossil and renewable, fuels in these countries is still wide spread. The use of such fuels does sometimes have severe negative impacts on the environment. This paper gives an overview of the use of various renewable and alternative fuels in the heavy clay industry in several countries and the environmental and financial impacts these fuels have or might have on the operation of a typical installation in various parts of the world (Maghreb, Europe, USA, Australia,India, Vietnam). Two examples in which alternative fuels have been or are used, one in an industrializing and one in an industrialized country, are briefly presented. A comparative product life cycle analysis, LCA, is presented

Innovative Biogas Multi-Stage Biogas Plant and Novel Analytical System

AbstractThe here presented applied research and development project is targeted to the development and application of new and improved techniques in plant design, performance analysis and process control. Hereto following the required steps are illustrated and the goals are outlined. The project covers the development of a previously patented anaerobic digestion process, adaption of flow cytometry as an analytical instrument and investigation of innovative ways of disposal of solid fermentation wastes. The preliminary experiences with a newly built research plant employing a novel anaerobic biogas digestion technique are discussed. In this paper the first outcomes concerning the construction and operation are discussed. A novel method of disposal of the fermentation wastes is also discussed and first results are shown

Municipal Solid Waste treatment by integrated solutions: energy and environmental balances

This paper reports a comparison between two scenarios developed in order to manage the municipal solid waste in an area in the North part of Italy. In the proposed scenarios various technological solutions, regarding the selective collection, the energy recovery and the modality of final disposal were taken into account. The comparison was done considering both mass/energy and environmental balance, trying to focus the most suitable solution. The experience can be completed with other scenarios containing different technical solution intermediate between the two considered in this study

Innovative biogas multi-stage R&D plant – preliminary project experiences

This paper summarizes the challenges and problems faced in designing, building and authorizing for operation of a novel cascade anaerobic digestion plant introducing a novel analytical method. For the R&D plant itself problems are mostly associated with preliminary unknown substrate characteristics and sizing whereas the challenges are mostly of administrative nature, i.e. authorizations and location. For the analytical method the problems and challenges are the application of an analytical method to a new field of application
