Packaging waste forms a significant part of municipal solid waste and has caused increasing environmental concerns, resulting in a strengthening of various regulations aimed at reducing the amounts generated. Among other materials, a wide range of oil-based polymers is currently used in packaging applications. These are virtually all non-biodegradable, and some are difficult to recycle or reuse...

This article examined the effect of a bioproduct suspension obtained from fermentation biodiesel’s crude glycerol when used to formulate natural hydraulic lime mortars, as fluid replacing mixing water. The was either sonicated or non-sonicated and two volumes were tested. aim assess advantages drawbacks that could be achieved with waste-based bioproduct, instead petrochemical-based additions. i...

background detergents and difficulties of their presence in the water and wastewater cause various problems such as foam production, anomalies in the growth of algae, and accumulation and dispersion in aqueous environments. objectives the aim of this study was to examine and compare the moving bed biofilm reactor with another reactor without media (carries) for anionic surfactants removal. mate...

Laccase is an enzyme that has potential ability of oxidation. It belongs to those enzymes, which have innate properties of reactive radical production, and its utilization in many fields has been ignored because of its unavailability in the commercial field. There are diverse sources of laccase producing organisms like bacteria, fungi and plants. Textile, pulp and paper industries discharge a h...

One of the industrial areas in the south of Iran is Bandar Imam Petrochemical Economic Zone which has a lot of petrochemical complex, Farabi Petrochemical complex is one of those places. Coagulation/flocculation could be a typical methodology in water and wastewater treatment that a number of chemicals are added to assist the coagulation/flocculation and causes to the sedimentation. In this pap...

After the first life cycle of plastics various recycling processes are available for further utilization of these valuable materials. For an ecologically and economically satisfying solution the most suitable process has to be chosen. In chemical recycling polymers are degraded to basic chemical substances which can be reused in the petrochemical industry. For soiled waste plastics or waste pla...
