The growing population all around the world has increased the quantum of solid waste the disposal of which has become a complex task to the municipal authorities. In search of a suitable remedy to this problem we have arrived at a number of varieties of waste management methods and strategies for dealing with municipal solid waste. These technologies help to generate energy in the form of heat, electricity and fuel and also remarkably reduce the diversion of biomass waste from landfill. The process of plasma gasification is one among those successful proven technologies of producing energy from waste. Gasification is a process in which a solid material containing carbon, such as coal or biomass, is converted into a gas called syngas which contains hydrogen and carbon monoxide. The focus of the paper is to analyze the process of plasma gasification and also to propose a critical assessment of MSW. It also aims to compare the performance of the process to that of the conventional energy recovery methods.

Concrete, after water across the world, the second most broadly utilized material involving 8-10% of all yields of CO2, is predominantly because of cement. This project ultimately aims to determine the potential use of Ferrock as an exceptional replacement for cement in concrete compared with other alternative alternatives. It is a steel-based restraining compound used to form a carbon-negative structure substance utilizing waste material absorbents. The iron residue (an iron business loss) that would end in sites somehow alongside small quantities of limestone, metakaolin, and fly ash is being used to make this an efficient substance. Our research focuses unexpectedly on their commitment to carbon dioxide contamination, energy use, water use, the ecologic impact of ordinary Portland cement and Ferrock (limestone 8%, metakaolin 12%, fly ash 20%, and iron residue 60%). By subtitling concrete with Ferrock in fluctuating proportions of 5%, 10%, 15%, and 20% in solid, we attempt to find the ideal proportion of substitution, which, along with sustainability, would boost wanted outcomes for both (compressive and divided tensile). In all this proportion, the test result shows 10% is more efficient than others.
