Mapping of the Use of Waste as Raw Materials for Biogas Production
Anthropic methane emissions can largely be prevented or minimized using technologies that are already available. One such technology is anaerobic digestion (AD), which is used commercially around the world, especially in Europe and the United States, where some challenging targets have been set to diversify the energy mix with more renewable energy. This foresight study was designed to identify...
متن کاملHorizontal Standardization and Harmonization of Leaching Test Methods for Waste, Secondary Raw Materials, Construction Materials and (contaminated) Soil
In recent years, a lot of work has been carried out in evaluating environmental impact from a wide variety of materials in a wide range of different applications. The continously recurring inability to compare results between different jurisdictions and between disciplines can be resolved by focusing on a limited number of key test methods. This does require the recognition that many existing t...
متن کاملValorization of Phosphorus Secondary Raw Materials by Acidithiobacillus ferrooxidans.
This paper presents the possibility of producing phosphorus fertilizers through Acidithiobacillus ferrooxidans utilization in secondary raw materials solubilization. Phosphorus was obtained from the bones of poultry and fish as well as from Morocco phosphorite. Four doses of poultry bones and fish bones were used in the experiment (2, 4, 10 and 20 g/L) and two doses (2 and 4 g/L) of phosphorite...
متن کاملA hazardous waste from secondary aluminium metallurgy as a new raw material for calcium aluminate glasses.
A solid waste coming from the secondary aluminium industry was successfully vitrified in the ternary CaO-Al(2)O(3)-SiO(2) system at 1500 degrees C. This waste is a complex material which is considered hazardous because of its behaviour in the presence of water or moisture. In these conditions, the dust can generate gases such as H(2), NH(3), CH(4), H(2)S, along with heat and potential aluminoth...
متن کاملFats and oils as oleochemical raw materials *
Vegetable oils and fats are important constituents of human and animal foodstuffs. Certain grades are industrially used and, together with carbohydrates and proteins, are important renewable resources compared to fossil and mineral raw materials, whose occurrence is finite. In concepts for new products, the price, performance, and product safety criteria are equally important and have a corresp...
