Development of broiler offal silage with molasses
Monday, January 21st, 2008Objective of the present study was to determine the feasibility of ensiling broiler offal (BO) with molasses. Forty two-days old broiler chicks were slaughtered and processed manually. Offal without feathers were cut into small pieces and ensiled in airtight plastic containers for four weeks. The experiment followed a completely randomize design in 4*2 factorial arrangement. [...]

Studies on utilization of sewage waste water for greening wastelands through afforestation
Monday, January 21st, 2008One of the major burning problems in urban areas is the disposal of sewage water, which degrades the environment, and as well as creates health hazards to human beings. One opening to this bottleneck is that this sewage water could be diverted for irrigation purpose especially for afforestation purpose. Sewage water provides nutrients and using [...]
An investigation of the effectiveness of locally available materials as oil spill sorbents for Sri Lanka
Monday, January 21st, 2008The effectiveness of seven locally available natural organic materials as oil spill sorbents was tested. The study specifically focused on determining, the behaviour of loose material on a layer of oil, oil sorption capacity of different types of materials and the viability of using them under actual field conditions. The seven natural organic materials were [...]
Utilization of sewage sludge as a potting media for tree nursery
Monday, January 21st, 2008Dumping of sewage sludge in the outer of cities leads to silting of nearby tanks, polluting the lands and also air they burn, which is a burning problem in urban areas. This sewage sludge is rich in nutrients and their use has been found to improve the physical condition of the soil as well as [...]
Wastewater use in agriculture in Sri Lanka: A case study from Kurunegala Sri Lanka
Monday, January 21st, 2008Wastewater management, including treatment, is vital to protect human health and prevent the contamination of lakes and rivers; but for most developing countries this solution is prohibitively expensive. In such cases, applying wastewater to agricultural lands is a more economical alternative and more ecologically sound than uncontrolled dumping of municipal effluents into lakes and streams, [...]
