Malaysia has great potential for biomass stock. The fact that oil palm fronds contain high moisture content makes it unsuitable to be used directly as a biomass fuel neither for direct combustion nor gasification. Conventional and costly drying methods make the fronds a non-attractive fuel especially in humid tropical countries, where sources of biomass is abundant. A new solar dryer design is proposed that utilizes concentrated solar thermal energy for drying oil palm fronds. A prototype for the dryer has been fabricated and tested. The system’s target is to maximize the thermal energy received by the system and to minimize energy loss out of the system. Experiments were performed on samples of oil palm fronds at a drying temperature not exceeding 110°C; in order not to affect the organic material of the biomass. Results were compared with another experiment performed at the same temperature. An electric oven was used for drying. The samples were completely dried using the proposed system for 6.5 hours, compared to 10.5 hours by using the electric oven. The proposed system achieved an average drying rate of 4.75 g/hr compared to an average drying rate of 2.83 g/hr using the electric oven. The efficiency of the dryer was calculated to be 55.4%, implying good potential of the proposed system.

Porous concrete planted with grass is attractive both environmentally and esthetically for applications in residential driveway, sidewalk and parking lots. Disposal of papermaking sludge is a challenging environmental problem. As a possible solution, grass cultivation in porous concrete filled with mixtures of papermaking sludge and soil was studied.

The optimum ratio of the papermaking sludge to soil appears to be in the range of 25 to 50%. Therefore, it is believed that papermaking sludge is suitable for grasses cultivation in the porous concrete.

The result of this experiment is encouraging and supportive of the better way for pasteurization the pineapple juices and increasing longevity of pineapple juices.

Lubrications industry is widely expand throughout the years. Well established mineral oil based promised the highest demand all over the world. But as the environmental concern is debated at most of world conferences, people are thinking to find the alternative for mineral oil replacement due to its non-biodegradable behaviour. The best suited source that having quite a par characteristic with mineral oil is vegetable oil. Vegetable oil is well known with its super bio-degradable characteristic. The source is renewable and does not require huge cost as compared to mineral and synthetic oil in term of exploration, development, production and transportation. Palm oil based is best suited among the vegetable oil series because of its stability and sources around the world. The major issue of palm oil based lubricant is low oxidative stability as the lubricant is commonly used at very high temperature and long shelf life application. Therefore some modification of molecule structure is needed by adding selected anti-oxidant at certain ratios. Tertier-butyl-hydroquinone (TBHQ) is used as anti-oxidantin this study. The results showing that a sufficient concentration of anti-oxidantprovides better solution for the low oxidative stability issues raised in palm oil based lubricants. The TBHQ also showed good characteristic in protecting two mating surfaces in wear scar analysis.

The sulfur content of diesel-like fraction is 10 times higher than that of diesel, and other fuel characters were similar with that of diesel, which indicated that diesel-like fraction was promising to substitute for diesel. After adding 10% diesel-like fraction into 5 # diesel, the fuel characters of diesel changed so little that it did not influence the application of diesel, which would be significant to alleviate the shortage of petroleum.

The treatment efficiency of domestic sewage by the SBR filled with humus soil was investigated and compared with that by the conventional SBR. The results show that the removal rates of organic matters, NH4+-N and TP by the SBR filled with humus soil reach 85%, 83% and 72% respectively.

Experimental research on the characteristics of co-combustion coal and combustible gas has been carried out. The influence of nozzle position and combustible gas reburning ratio on N2O and NO removal rate were carried out at CFB experimental platform. It is found that N2O removal rate achieved a maximum value when the reburning gas was injected into furnace from nozzle C with a height-diameter ratio of 8.3, and the NO removal rate is about 50%; When the combustible gas were injected into furnace from nozzle C, the N2O removal rate kept increasing with the increase of reburning ratio (Rm), which can reach 99% when the Rm value is 10.5%. In addition, the NO removal rate is increasd after the first reduction with the increase of Rm, when the rate is about 39% with Rm is 10.5%.

China is the biggest country in producing and using of bamboo and wood products for food in the world. The quality status of the bamboo and wood products for food concerns the safety of everybody. Samples were taken for safety indexes testing from the provinces of the main production, and marketing of the bamboo and wood products for food at home. A preliminary conclusion of quality and safety status of the bamboo and wood products for food was drawn via the analysis for testing results, and some foundation work has been done for the quality control of the bamboo and wood products for food.
