Despite the high potential to increase sustainability of food systems, wastes and byproducts occurring in the food supply chain are currently only partially valorised at different valueadded levels. First-generation valorisation strategies that aim at utilisation of complete material streams for production of animal feed, energy, compost and/or specific consumer applications are already widely ...

Overpopulation is no doubt worldwide concern as it brings different problems to urbanization process as well as environment. Waste is number one side product of overpopulation. Waste generation is ever increasing in both urban and suburban area and has led to many environmental issues. Many of the waste generated have potential to be transformed into value added products. By recycling, reusing ...

Thermal desorption, by a rotary kiln of mercury contaminated soil and mine wastes, has been used in order to volatilize mercury from the contaminated medium. Solar thermal desorption is an innovative treatment that uses solar energy to increase the volatility of contaminants, which are removed from a solid matrix by a controlled air flow system. Samples of soils and mine wastes used in the expe...

Animal by-products (ABP), containing mainly rabbit and chicken carcasses were composted at laboratory scale. Results indicate that if proper conditions are used, wastes can be successfully composted and stabilised meeting current European hygienisation standards regarding the disposal of this type of wastes. During the process, temperatures above 60 degrees C were easily reached and maintained ...

Wireless sensor networks is an emergent technology which has made Ambient Intelligence a reality. It consists of several tiny nodes connected to each other in Ad hoc environment and coordinate with each other to form a network. It has wide range of applications, potential in areas such as intruder alert and tracking, environmental monitoring, industrial process monitoring, and tactical systems....

1270 Journal of Chemical Education • Vol. 75 No. 10 October 1998 • JChemEd.chem.wisc.edu There is current interest in and concern for the development of environmentally friendly bioprocesses whereby biomass and the biodegradable content of municipal wastes can be converted to useful forms of energy. For example, cellulose, a glucose polymer that is the principal component of biomass and paper w...

The effects of replacing 50% of cereals-based concentrate with feed blocks (FB) including wastes of tomato fruits (diet ACT), wastes of cucumber fruits (diet ACC), or barley grain (diet ACB) on nutrient use, ruminal fermentation, microbial N flow to the duodenum, methane emissions, and abundances of total bacteria and methanogen were studied in goats. Four adult, dry, nonpregnant, rumen-fistula...

barrels of oil equivalent (boe) The total energy content of a non-petroleum-based product or fuel in GJ divided by 5.904 6.115 GJ/boe. biodiesel The methyl or ethyl esters of transesterified triglycerides (lipids, fats, cooking greases) from biomass. biofuel A solid, gaseous, or liquid fuel produced from biomass. biogas A medium-energy-content gaseous fuel, generally containing 40 to 80 volume ...

(1) Potential uses of photosynthetie bacteria in the recycling of human wastes have been considered. I t is concluded that systems using photosynthetic bacteria may have advantages over purely algal systems under conditions where total recycling is needed and energy is not abundant. (2) Two systems are proposed in which the metabolic potential of the photosynthetic bacteria might be realized. B...
