Biodegradability enhancement and detoxification of cork boiling wastewater (CBW) are required for the successful implementation of biological treatment options. We studied the possibility of achieving these goals through ozonation pre-treatment by experimenting on the effect of ozone dose and pH. The CBW used had a pH of 5.81, a chemical oxygen demand (COD) of 1,865 mg L(-1), a biochemical oxyg...

The present study was conducted to determine the recyclability and biodegradability of bamboo fabric-reinforced poly(lactic) acid (BF-PLA) composites for sustainable packaging. BF-PLA composite was recycled through the granulation, extrusion, pelletization and injection processes. Subsequently, mechanical properties (tensile, flexural and impact strength), thermal stability and the morphologica...

Surfactants are extensively employed in industrial, agricultural, and food, cosmetics pharmaceuticals applications. Chemically produced surfactants cause environmental toxicological hazards. Recently, considerable research has led to environmentally friendly procedures for the synthesis of several forms biosurfactants from microorganisms. In comparison chemical surfactants, have advantages, suc...

Abstract Cellulose acetate with a degree of substitution (DS) 2.5, commonly referred to as cellulose diacetate, has been discussed an important source microplastic in the environment, especially since it is used produce cigarette filters. According EU Single-Use Plastics Directive tobacco products are one ten most found SUP beach litter by number. However, at present only very few biodegradatio...

The influence of sodium hydroxide addition during the thermo-chemical pretreatment of a microbial biomass has been evaluated in terms of particulate chemical oxygen demand (COD) solubilization and anaerobic biodegradability. Both COD solubilization and total solid elimination rates increased with the dose of NaOH added: COD solubilization reached 63%, and total solid elimination was 33% when 5 ...

A variety of renewable starting materials, such as sugars and polysaccharides, vegetable oils, lignin, pine resin derivatives, and proteins, have so far been investigated for the preparation of bio-based polymers. Among the various sources of bio-based feedstock, vegetable oils are one of the most widely used starting materials in the polymer industry due to their easy availability, low toxicit...
