The expansion of oil palm cultivation in Indonesia has been driven by a strong world demand for food especially fats and oils. Commencing in the island of Sumatra, it spread out to other island like Kalimantan, Sulawesi and Irian but not to the island of Bali which was already well developed. The role of palm oil in developing remote inland regions and improving the standard of living of rural ...

agaricus bisporus is the most important industrially cultivated edible mushroom. using organic wastes as substrate for cultivation of edible mushroom can provide a perfect solution for disposal of these waste materials and is part of the world's food requirements .in this study to investigate the usability of various organic wastes as growing bed for button mushroom, four types of substrat...

This paper examines the links between solid urban waste management and peri-urban agriculture in Bamako and Ouagadougou. Staple crop farmers in the vicinity of both cities value urban waste as a source of organic matter and are prepared to pay for it. Cultivation on degraded soils has even been revived in some cases thanks to this readily available resource. However, uncertain land tenure means...

A wide variety of waste bioresources are available on our planet for conversion into bioproducts. In the biological systems, microorganisms are used to utilize waste as an energy source for the synthesis of valuable products such as biomass proteins and enzymes. The large quantities of byproducts generated during the processing of plant food involve an economic and environmental problem due to ...

Among the various environmental issues, waste management is a foremost area where effectual and exhaustive consumption of wastes and attaining useful products in natal ways are concentrated. Cassava the tuber crop, exploited for starch and sago production.The aim of this work is management of cassava sago industrial waste, because its availability is vast particularly in salem. Bio ethanolhigh ...

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...

Background. Polyhydroxyalkanoates (PHAs) are storage materials that accumulate by various bacteria as energy and carbon reserve materials. They are biodegradable, environmentally friendly, and also biocompatible bioplastics. Unlike petrochemical-based plastics that take several decades to fully degrade, PHAs can be completely degraded within a year by variety of microorganisms into CO2 and wate...

East Calcutta Wetland (ECW) is an example of wise use of cities solid and liquid waste through integrated resource recovery, mainly for pisciculture, vegetable as well as paddy cultivation and manure production. Amaranthus caudatus, Amaranthus blithum and Spinacia oleracea grown at ECW were analyzed for their accumulation of elements using Energy Dispersive X Ray Fluorescence (EDXRF) and compar...

Microalgae are fast-growing photosynthetic organisms which have the potential to be exploited as an alternative source of liquid fuels to meet growing global energy demand. The cultivation of microalgae, however, still needs to be improved in order to reduce the cost of the biomass produced. Among the major costs encountered for algal cultivation are the costs for nutrients such as CO₂, nitroge...
