This Special Issue of Bioresource Technology is dedicated to selected contributions presented at the international Workshop: ‘‘Livestock waste treatment systems of the future: A challenge to environmental quality, food safety, and sustainability,” held 2–4 April, 2008, in Florence, South Carolina (USA) and sponsored by the OECD (Organisation for Economic Co-operation and Development), Cooperati...

As manufacturing industries become more cognizant of the ecological effects that their firms have on the surrounding environment, their waste streams are increasingly becoming viewed not as materials in need of disposal, but rather as resources that can be reused, recycled, or reprocessed into valuable products. Within the food processing sector there are many examples of value-added use of pro...

Livestock contributes directly to the livelihoods and food security of almost a billion people and affects the diet and health of many more. With estimated standing populations of 1.43 billion cattle, 1.87 billion sheep and goats, 0.98 billion pigs, and 19.60 billion chickens, reliable and accessible information on the distribution and abundance of livestock is needed for a many reasons. These ...

Water is a vital but poorly studied component of livestock production. It is estimated that livestock industries consume 8% of the global water supply, with most of that water being used for intensive, feed-based production. This study takes a broad perspective of livestock production as a component of the human food chain, and considers the efficiency of its water use. Global models are in the...

This study was conducted to provide a detailed description of waste generation and characteristics from a traditional market in Hue city, located in central Vietnam. The authors conducted a waste generation survey and a waste composition survey for 309 stalls/vendors in five markets by 17 business categories for 10 consecutive days. The waste generation rates by stall/vendor and by floor area w...

The production of methanol from agricultural, forestry, livestock, poultry, and fishery waste via pyrolysis was investigated. Pyrolysis was conducted in a tube furnace at 450-500 °C. Sugarcane bagasse showed the methanol production (5.93 wt.%), followed by roots and sawdust with 4.36 and 4.22 wt.%, respectively. Animal waste offered the lowest content of methanol, as only 0.46, 0.80, and 0.61 w...

10 In developed Countries, coexistence of livestock production and urban settlements is a source of 11 problematic interactions that are regulated by specific legislation, often requiring the evaluation of 12 the potential environmental impact of livestock odour emissions. For this purpose, dispersion 13 models are powerful tools that can be classified as dynamic (Eulerian and Lagrangian) or st...

Large-scale production of antibiotics began in the 1940’s. Almost immediately, the use of antibiotics spread to agricultural uses. In livestock, antibiotics are used to reduce illness. However, a far more common use is to increase feed efficiency, resulting in better profits. (Coghlan, 1996 and Bonner, 1997) With the widespread use of antibiotics has come a variety of concerns. Primarily, fear ...
