One of most common types municipal solid waste treatment is mechanical-biological (MBT), which in practice has many variations depending on the method conducting technological process and it possible to get different output fractions. In this paper analysed generated after MBT with biodrying, where mechanical undergoes then RDF (recovery derived fuel) separated. Fine fraction remains a high con...
In recent decades, a new generation of waste treatment plants based on biological treatments (mainly anaerobic digestion and/or composting) has arisen all over the world. These have been progressively substituted for incineration facilities and landfills. Although these evident benefits in terms their environmental impact higher recovery material energy, release into atmosphere malodorous compo...
Background and aim: Today, hospital waste is one of the problems facing human societies. Hospital waste contains toxic and dangerous compounds, infectious substances, biological microorganisms, toxic chemicals effluents (resulting from x-ray film processor and disinfectants) and pharmaceutical compounds. The absence of treatment and improper disposal can be a very dangerous to the environment ...
Waste refineries focusing on multiple outputs of material resources, energy carriers, and nutrients may potentially provide more sustainable utilization of waste resources than traditional waste technologies. This consequential life cycle assessment (LCA) evaluated the environmental performance of a Danish waste refinery solution against state-of-the-art waste technology alternatives (incinerat...
In the favourable current context for the development of biological treatment of Residual Municipal Solid Wastes (RMSW), the Rotary Drum Reactor (RDR) is a pre-treatment tool increasingly used in construction or rehabilitation facilities. RDR allows a better preparation of waste before mechanical sorting and biological treatment. This preparation process, recognized by profession’s actors, is h...
Anaerobic digestion (AD) of organic municipal solid waste (OMSW) is considered as a key element in sustainable municipal waste management due to its benefits for energy, environment, and economy. This process reduces emission of greenhouse gases, generates renewable natural gas, and produces fertilizers and soil amendments. Due to its advantages over other treatment methods and waste-to-energy ...
Olive-oil production is of vital importance for the economy and social life of the Mediterranean region; however, the side effect of the olive-oil mill activity is the generation of enormous quantities of biotoxic olive-mill waste within a short period of three months. Numerous physicochemical and biological methods have been used in the past for the treatment of both olive mill wastewater (OMW...
