Recovery Technology of Energy from Waste Tank Sludge.

Colloidal Agglomerates in Tank Sludge: Impact on Waste Processing

Energy Recovery from Used Disposable Diapers by Co- Digestion with Waste Activated Sludge

The results presented in this paper are part of a project aimed at designing an original solution for the treatment of used disposable diapers permitting the recycling of materials and the recovery of energy. Diapers must be collected separately at source and transported to an industrial facility to undergo special treatment which makes it possible to separate plastics and to recover a biodegra...

Zinc recovery and waste sludge minimization from chromium passivation baths.

This work reports the feasibility of applying emulsion pertraction technology (EPT) aiming at zinc recovery and waste minimization in the zinc electroplating processes that include Cr (III) passivation. The assessment consists of firstly the lifetime extension of the passivation baths by selective removal of the tramp ions zinc and iron, and secondly, the recovery of zinc for further reuse. Spe...

Feasibility of nutrient recovery from industrial sludge by vermicomposting technology.

Transformation of industrial sludges into vermicompost is of double interest: on the one hand, a waste is converted into value added product, and, on the other, it controls a pollutant that is a consequence of increasing industrialization. This paper reports the feasibility of utilization of vermicomposting technology for nutrient recovery from industrial sludge in laboratory scale experiment e...

Energy Recovery from Waste Incineration—The Importance of Technology Data and System Boundaries on CO2 Emissions

Previous studies on waste incineration as part of the energy system show that waste management and energy supply are highly dependent on each other, and that the preconditions for the energy system setup affects the avoided emissions and thereby even sometimes the total outcome of an environmental assessment. However, it has not been previously shown explicitly which key parameters are most cru...
