This paper discussed the influences of plasma processing time and power on wool fibers, the results showed that: after plasma treatment, the surface of the wool fibers occurred varying degrees of physical and chemical etching phenomenon, the wetting property was increased significantly, anti-shrinkage performance was improved. Breaking strength and elongation at fracture were increased; the beginning of dyeing properties and the balance rate were increased.

Brazil has one of the largest herds of cattle in the world, with more than 170 million heads. Over 400 farms have exported more than 2,875 ton (in 1997) of leather to Europe. The wet blue tanning process uses chemicals such as chromium compounds and produces liquid wastes that must be treated by physico-chemical and biological systems. About 15,000 ton per month of dewatering sludge with 24% solids content is disposed of into landfills. During the process, pre-tanned skins (wet blue leather) are shaved to the desired thickness and the shavings, like sludge, are among the wastes that must have special attention. The organic content and chromium concentration are high. About 12% of the leather production from cattle hides are shavings, and its chromium concentration ranges from 3.5 to 5.5% of dry matter. The Environmentally friendly leather project, a co-operation between Brazilian and German tanneries, universities and technical schools, is looking for process optimisation, waste minimisation and adequate treatment for solid and liquid wastes from the leather industry. This work presents results of Low Temperature Conversion of chrome-containing sludge and shavings in a laboratory batch reactor, offering a solution for these hazardous wastes, recovering the energy content and transforming metals in insoluble sulphides.

Indonesia has a typical rice processing method as part of the nation’s culture, namely ketupat. Ketupat is typical food made of rice wrapped in diamond shaped-woven coconut leaves and boiled in water. This article reviewed the variety of processing ketupat as well as changes in ketupat during storage of ketupat according to the results of research and related references. Traditionally, ketupat is cooked in boiling water for 5 hours. This is considered inefficient in terms of cooking fuel and time required for cooking. The efforts of modifying ketupat cooking method have been done to shorten processing time, such as cooking ketupat in pressure cooker for 30 minutes. The development of ready-to-cook ketupat or quick-cooking product in attractive package becomes a promising opportunity. Quick-cooking ketupat was made by immersing ketupat in salt, steaming, freezing and drying. The package of quick-cooking ketupat was designed using HDPE plastics made square shape that requires boiling period for 30 minutes. Ingredients and the amount of rice, the size of coconut leaves, immersion process and cooking technic affected the texture of ketupat produced. Ketupat is normally stored for 2 days in room temperature and 4-7 day if it is refrigerated. Spoilage of ketupat is due to microbiological and physical changes during storage. Starch retrogradation and increase in RS III may occur when ketupat is stored at low temperature.
