Incineration of municipal solid waste is a debated waste management technology. In some countries it is the main waste management option whereas in other countries it has been disregarded. The main discussion point on waste incineration is the release of air emissions from the combustion of the waste, but also the energy recovery efficiency has a large importance. The historical development of ...

E-waste contains high amount of brominated flame retardants (BFRs) which are toxic, bioaccumulative and recalcitrant. In the present study, an effective and environmental-friendly process using solvothermal treatment to extract tetrabromobisphenol A (TBBPA), a typical BFR from waste computer housing plastic was developed. After the solvothermal process, TBBPA were transferred into a special sol...

Medical waste poses a serious threat to the environmental health without comprehensive guidelines and efficient management as it contains highly toxic chemicals, pathogenic viruses and bacteria. Therefore, proper handling of medical waste with specialised treatment from its source to final disposal has been a primary concern among medical institute, public and private agencies. The existing med...

The conditioning of biosolids is a growing issue due to extremely large increases in production of this waste, escalating disposal costs and inefficient use of produced methane. One approach to improve biosolids utilization is treating waste activated sludge (WAS) before anaerobic digestion to enhance digestion, increase methane production and lower biosolids production. Cavitation is the dynam...

Biosorption is most economical method for removing toxic metals from waste water.The paper presents the results of studies carried out on sorption of zinc ions from aqueous solutions by a coffee industry waste s a low-cost sorbent. It was found that crushed coffee industry waste possess relatively high sorption capacity as 46.05 mg/g, when comparing with other sorbents. The biosorption studies ...
