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. […]
Utilization of oil palm waste as a low cost feed ingredient for growing pigs to reduce the environmental pollution
Monday, January 21st, 2008Oil palm is the one of the most popular oil crop in many regions of the world and it plays an important role as a component of animal feed and as a cooking material in an industrial sector. However, every ton of oil produced generates tons of effluent and this cannot be released to the […]
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, […]
Suitability of some agro-industrial by-products as litter material for poultry: Physio-chemical properties
Monday, January 21st, 2008Paddy-husk (PH) based deep litter system is the most popular poultry management system in Sri Lanka. Physio-chemical properties of PH make it an ideal litter material for poultry keeping. Since PH is increasingly been demanded by other industries, availability of PH for poultry industry has been restricted from recent years. Objective of the present study […]
Media properties of different vermicompost and coir dust mixtures
Monday, January 21st, 2008In recent years, the demand for coir dust has increased as it is widely used as a growth medium in soil less culture. Since it is low in nutrients, when mixed with vermicompost, will provide a better growth medium for plant establishment. Therefore, this study was carried out to evaluate the properties of different vermicompost […]
Shrimp waste management: Use of dried papaya milk in chitosan manufacture
Monday, January 21st, 2008Chitin is the second most abundant carbon biopolymer on earth, next to cellulose. It is the major constituent in the exo-skeleton of crustacean water animals such as shrimps, crabs etc. Shrimp waste is a major cause for environmental pollution in shrimp cultivating areas such as Puttalam. Current annual shrimp production in Sri Lanka is about […]
Development of a flexible porous pipe using rubber crumb and recycled
Monday, January 21st, 2008The main objective of this study is to develop a porous flexible rubber pipe utilizing the rubber crumb and recycled polyethylene for micro irrigation system to maintain under ground moisture content.
The research work was mainly based on the formula development and the process development. Initially number of formulations based on the plastic binder and vulcanized […]
