Metropolitan areas are large consumers of energy and there is a growing need to broaden the urban sustainable energy diapason and increase the share of renewable and sustainable energy in overall energy consumption. This is especially important in countries such as Serbia that have limited domestic fossil fuel resources and rely on energy imports, from the environmental, financial and energy se...

The management and disposal of sewage sludge is becoming a growing concern at the global level. In past, main goal was to completely eliminate since it deemed threat humans environment, but recently different possibilities for energy generation material recovery are emerging. Existing technologies such as incineration or direct application in agriculture contribute quantity reduction nutrient u...

Waste incineration fly ash and bone powder could be successfully recycled to calcium phosphate hydrogel, a type of fast proton conductor. The electric conductivity of the crystallized hydrogel from them was compared with that from calcium carbonate reagent. It was found that the conductivity of the hydrogel from bone powder is almost equal to that from calcium carbonate reagent, which is higher...

Abstract Economic growth and rapid industrialisation have led to enormous increase in municipal solid waste (MSW). Lack of management alternatives ineffective policy implementation are the major challenges for government materialise a sustainable framework, especially plastic waste. Booming food beverage (F&B) industry has aggravated situation by generating more with no economic values. Hen...

A new computer based life cycle assessment model (EASEWASTE) was used to evaluate a municipal solid waste system with the purpose of identifying environmental benefits and disadvantages by anaerobic digestion of source-separated household waste and incineration. The most important processes that were included in the study are optical sorting and pre-treatment, anaerobic digestion with heat and ...

Polychlorinated dibenzo-p-dioxins (PCDD) and polychlorinated dibenzofurans (PCDF) are fonned unintentionally as bypro ducts of waste combustion and many other thelmal industrial processes. Today PCDDIPCDF is known as one of the most toxic groups of organic substances. Furthelmore, they are perceived to be carcinogenic. Although many questions about the toxicological effects of PCDDIPCDF are sti...

Despite progress in residential waste diversion, residual waste - that fraction which cannot be recycled or composted - must continue to be managed by municipalities. Zero waste and environmental groups worry that waste-to-energy (WtE) incinerators discourage diversion, while both incineration and landfill have been stigmatized in the popular consciousness such that WtE incinerators in particul...

Resource recovery from waste streams in a space habitat is essential to minimize the resupply burden and achieve self-sufficiency. In a Controlled Ecological Life Support System (CELSS) human wastes and inedible biomass will represent significant sources of secondary raw materials necessary for support of crop plant production (carbon, water, and inorganic plant nutrients). Incineration, pyro...
