FAO reported in year 2008 world paddy production more than 40 countries and about 60 million tones of rice straw were produced in Thailand. For most farmers use an easy method for land clearing by straw burning in open area. Greenhouse gases such as carbon dioxide(CO2) emissions from paddy field burning to atmosphere is causes of global warming problem. This project aimed to utilize agricultural waste from rice field to be cheap biomass energy was started in 2009 at Nhongjork area. The waste was mixed with molasses and kaolin in ratio of rice straw : molasses : kaolin as 80:10:10 by weights. A size of rice straw fuel pellet was 1.54 cm. diameter and 2 cm. height. The calorific value of the rice straw pellet was tested by using Gallekamp Autobomb instrument by ASTM(American Society of Testing and Materials) standard. The results of testing found : CO2 emission from rice straw fuel pellets as half of burning in open area (by weight). Cost of energy for cooking by using Bio-fuel pellets only 7 Baht( 0.25 US $) and half price by comparing with LPG. The useful of rice straw Bio-fuel pellet is one of a cheap biomass energy for household and small manufacturers.

The objective of this research project is to develop an effectively applicable prevention of heat for concrete masonry unit wall. By using kaolin mixture coir rice straw and husk as a major ingredient in concrete to replacing usual stone dust the hollow non-load-bearing concrete masonry units obtained had the size of 70 X 190 X 390 mm. The test results showed that the reliably ideal ratio of these mixture materials had to be from the combination of kaolin coir rice straw and husk by replacing them at 5%: 5%: 15% and 50/0. The block obtained also had other certain qualifications such as Weight at 6.08 kg. water absorption at 7.96% and compressive strength at 65.4 ksc. Moreover these combined materials harbored heat capacity less than the standard concrete masonry units with the weight not more than 29%.

The objective of this paper was to study and development of rice straw paper and development of rice straw paper products-making. Part I. Rice straw paper-making. The bleached and unbleached with 2% HP2(aqJform rice straw fiber was boiled with 2% and 4% NaOH(aq) The 4 treatment was take out container and spread in to thin piece of paper. The 4 treatment were conducted to test physical properties and strength properties on rice straw paper. Part II Rice straw paper products-making. The populations in this research were 16 students and 16 teachers on RIT. Chotiwet Campus to making and evaluate the rice straw paper products. The instrument used in this research were questionnaires about the admission on specifics properties of rice straw paper products and satisfaction to rice straw paper products. The data were analyzed by SPSS program. The statistic used that mean standard deviation one way ANOVA and two way ANOVA. Differences between various groups were tested by Scheffs method.
