the physical properties of the municipal solid waste (msw) in kahrizak landfill (tehran, iran) and its changes due to aging were investigated in this research. a study of the components of the fresh msw in this landfill showed that more than 60% of it was made from the wastes of foods, fruits, vegetables and organic materials. next to that, paper/cardboard and plastics, with contributions of 14...

EXECUTIVE SUMMARY The activities conducted for the improvement of municipal solid waste (MSW) management in Hargeisa City, Somaliland capital city, are described hereafter. CeTAmb has been carrying on a study for the improvement of collection, recycling and disposal of MSW in Northern Somalia since 2005. The study was initially performed in collaboration with UNA Consortium within " Somalia Urb...

The present study focuses on process inhibitions in Danish centralized biogas plants. Collection of data from the plants and a number of interviews showed that inhibitions occur frequently. High concentrations of ammonia, long chain fatty acids or other inhibitory compounds, and foaming in prestorage tanks are well known causes of inhibition. These problems mainly occurs due to: 1) inadequate k...

inappropriate waste management is considered as an important factor for attracting wild animals to the inhabited area. this leads to food conditioning in some wild species, which changes their feeding behavior and food habits. usually this trend reduces the fear of wild species and leads to conflict between wild species and human. we sampled five landfill sites of villages and small towns in wh...

During 2010-2012 we carried out project Foodspill, concentrating on mapping the volume and composition of food waste in the Finnish foodchain. 380 households weighed their avoidable food waste each day when they disposed of food during a two-week research period. The average annual food waste was 23 kg per person, and for households 120–160 kg per annum. For the food service sector the amount, ...

During composting, the composition of microbial communities is subject to constant change owing to interactions with fluctuating physicochemical parameters. This study explored the changes in bacterial and fungal communities during cattle farm waste composting and aimed to identify and prioritize the contributing physicochemical factors. Microbial community compositions were determined by high-...

environment conservation is the common concern at all levels from local to global. most of the recent environment problems and ill effects stem from ecological misappropriation and neglect to recognize the limits of ecosystem, its. rapid population growth, low income, lowest health facilities, poor sanitation, lack of education. personal and community hygiene poverty has enhanced the incidence ...

The study was conducted at Pig farm of AICRP on Pigs, Livestock farm, Adhartal, College of Veterinary Science & A.H., Jabalpur (M.P.) for a period of three months. A total of 36 Large White Yorkshire crosses (LWY X Desi) were randomly assigned to six different groups and diets were formulated as per ICAR (1998) standard. All the diets were isoproteinous except group-6, which was formulated as p...

The tannery industry is a major source of anthropogenic chromium (Cr) contamination due to the large amounts of solid waste produced and its problematic management. The unique composition of tannery waste, usually high concentrations of Cr and other metals as well as organic matter and nutrients, makes it a great risk for soil and water environment but also a possible effective fertilizer for n...
