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 [...]

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 [...]
Studies on comparative assessment of tree borne oil species in Southern zone of Tamilnadu, India
Friday, January 18th, 2008Energy demand fulfillment from biological origin gets great attention in the recent times. Due to the large scale of energy demand, the bio fuel especially Tree Borne oil species (TBOs) got higher demand by its yield and sustainability. Among the tree born oil species, Jatropha curcas, Simarouba glauca, Pongamia pinnata, Madhuca indica and Azadirachta indica [...]
Consumption patterns of energy in rural sector of Sri Lanka – Analysis based on Puttalam district
Friday, January 18th, 2008The energy crisis is prominent in developing countries where explosive populations are experienced with inefficient utilization of energy and poor technologies. Sri Lanka also fails in meeting the total national energy demand and presently seeking for alternatives while scrutinizing the potentials of efficient use of available energy sources of bio mass (mainly fuel wood), [...]
Hybrid biogas plant producing electricity
Friday, January 18th, 2008Energy is the major cause behind the development of a nation. By thinking on it we have worked on the biogas plant and modified it to generate electricity. This generated electric current is sufficient enough to power an entire house. Also our idea can be implemented in country with huge amount of organic waste material.
Have [...]
Potential of cultivation of Gliricidia (Gliricidia sepium) in coconut triangle for bioenergy generation
Friday, January 18th, 2008Evaluation of least cost and environmentally friendly energy alternatives is essential to overcome the prevailing energy crisis. Dendro thermal energy generation has been identified as one of the best options due to its potential as a low cost and locally available environmentally sound energy source. However, this potential has not been exploited by the people [...]
