Waste to energy is an answer to the growing demand for fossil fuels. Pyrolysis plays an important role in waste to energy technologies. The product obtained from pyrolysis depends on various physical parameters that influence the reaction mechanism. Pyrolysis reactions can be classified onto flash, fast and slow pyrolysis depending on temperature and heating rate. This paper discusses the effec...

In this paper, we present a low-cost vision based system for handling of hazardous waste in an unstructured environment. The prototype system described shows the feasibility of sorting and removal of randomly mixed and oriented flexible objects from a bin using inexpensive and widely available hardware. Our experiments show that the utilization of even the simplest constructs is sufficient for ...

The biogas process has long been a part of our biotechnical solutions for the handling of sewage sludge and waste. However, in many cases the existing process applications need to be optimized to improve the extent of biogas production as a part of the energy supply in a sustainable and viable society. Although the principles are well known, process disturbances and poor substrate utilization i...
