Aqueous wastes containing organic pollutants can be eciently treated by wet air oxidation (WAO), i.e. oxidation (or combustion) by molecular oxygen in the liquid phase, at high temperature (200±325 C) and pressure (up to 175 bar). This method is suited to the elimination of special aqueous wastes from the chemical industry as well as to the treatment of domestic sludge. It is an enclosed proce...

In recent years, the biomass market has constantly increased. The pellet manufacture industry has started looking for new products, such as wastes from forest, agriculture, and agroindustrial residues, among others, with the potential to be used as biofuels. However, some of these wastes have some characteristics that make both the combustion process and operating and maintenance conditions of ...

background: production of solid waste is the result of the human’s different activities that today has changed a lot in comparison to the past due to the changing life styles and pervasive expansion. in isfahan province lots of wastes are produced daily. due to the importance of the waste and its recycling, the purpose is determining the production scopes of different wastes in order to find a ...

Plastics usage is rising daily because of increased population, modernization, and industrialization, which produces a lot plastic garbage. Due to their various chemical structures, long chain polymeric compositions, thermal/decomposition behavior, it challenging recycle these wastes into hydrocarbon fuels. In the current work, domestic waste was pyrolyzed at 473 973 K in fixed bed reactor comp...

This study investigated the quality of biomass fuel briquettes; a Refuse Derived Fuel (RDF) made from bio-wastes generated local farm produce market in Nekede, Owerri, Nigeria, known as Umuokomoche daily market. The wastes were mainly waste groceries; vegetable stems, leaves, fruits, plantain peels and yam potato peels, corn hob all sorts discarded food / agro materials which constitute over 70...
