The biological treatment processes found wide applications in wastewater, air & solid waste pollution control. The need for alternate cost effective treatment technologies led to similar biological treatment processes for waste gas streams. One such treatment technology is biofiltration. Biofiltration technology utilizes the microorganisms to biologically degrade Volatile Organic Compounds (VOC...

Recently, tetraphenylphosphonium bromide (TPPB) has been used to remove technetium from some radioactive waste streams. However, before TPPB could be approved for use it was necessary to show that TPPB and its degradation products would not have a significant detrimental effect on post-closure performance of a radioactive waste repository. TPPB is known to be stable at neutral pH, however, unde...

Residential domestic hot water (DHW) energy consumption represented 16% of the EU household heating demand in 2013. Due to the improvement of the building envelop, it is expected to increase significantly, with values between 20% to 32% in single family buildings, and between 35% to almost 50% in multifamily buildings. Currently, this energy is lost to the environment after its use, but it can ...

The waste-LCA model EASEWASTE quantifies potential environmental effects from biological treatment of organic waste, based on mass and energy flows, emissions to air, water, soil and groundwater as well as effects from upstream and downstream processes. Default technologies for composting, anaerobic digestion and combinations hereof are available in the model, but the user can change all key pa...

As there is a high potential for microbe-based technologies to bring the recovery of metals from waste streams to an ecologically friendly and financially reasonable level, it is worth to invest efforts into the advancement of these biotechnologies in the future.

The metal fmishing industry uses over 40 production processes to produce a wide range of metal products. Waste streams generated include wastewater, waste oils, spent solvents, and spent process solutions. Current1,v a wide variety of techniques which minimize waste are available. Cost-effective methods to reduce electroplating wastewater contamination include water conserv&ion and drag-out red...

Recent years have seen significant increases in the average heating values of wastes in Central Europe. Essentially, this can be attributed to recycling measures, separate recovery of waste streams, and treatment and processing procedures in modified waste management concepts. As a result of the above and due to the increasingly frequent application of energy recovery procedures for commercial ...
