Abstract
Bioethanol is one of the alternative sources of oil resources which received attention with biodiesel. Many countries produce bioethanol from food sources such as corn and sugarcane, but it causes food-energy conflicts and farmland problem. So it needs to focus on new biomass which is sustainable, renewable, cost-effective and do not occurred any conflicts. Algae are one of the bioma

♦Introduction
- What is benefits
Benefits is selected to the worker in a variety of item that designed to corporate. Workers assigned to them in the welfare budget and the rating based on their lifestyle and welfare items, and they can select the level of benefits.
Based on the selection of staff welfare and benefits of the information is determines the level of that. That was reflect
preservation technologies. Various modern technologies are applied to inhibit the growth of micro-organisms in food product as various food-spoilage micro-organisms are exit. Consequently, the techniques are so complicated and diverse to state in one paragraph. This report divides the methods into several categories, physical, biological, and chemical, and introduces each technology briefly.
High-temperature decomposition
High-temperature splitting of water occurs at about 3000 °C. At this temperature, 10% of the water is decomposed and the remaining 90% can be recycled. To reduce the temperature, other processes for high temperature splitting of water have been suggested:
▸Thermo-chemical cycles.
▸Hybrid systems coupling thermal decomposition and electrolytic
