Biomass gasification and power generation plant
Sanya Timber Factory is a large-scale timber processing enterprise that locates in Sanya, Hainan Island of China. About 100 tons wood waste is produced every day in this factory. Due to the complicated sorts of timber waste, some of the wastes are used and others are disposed which causes some severe problems of storage and pollution. On the other hand, timber processing is a high electricity consumption activity; this factory needs power about 5000 kW and the cost is up to ten million RMB per year. So to convert the wood waste into electricity for the factory’s self-consumption through biomass gasification-power generation technology has favourable conditions of environmental protection and energy conservation. A demonstration biogas gasification plant was made operational. When the demonstration plant operates under designed conditions, about 10 thousands tons of biomass wastes will be utilized every year. Consequentially, with the advantage of no CO2 release, more than 10 thousands tons of CO2 can be avoided. And comparing with coal combustion, a great deal of flue gas, such as NOx and SO2 can be alleviated. In the long term, the plat would provide economic as well as environmental benefit.

Biomass power lights up lives
Kasai, in Betul district's Bhainsdehi block, was the first village to be electrified using a biomass gasifier six months ago-the project was officially inaugurated only at the end of October. It was one of the villages that was identified as having no chance of getting electricity before 2012. But Kasai is now in the throes of change-every home is lit up by two bulbs and the only two lanes in the village have nine streetlights on at night. The Ministry of Non-conventional Energy and Resources spent 90 per cent of the total expenditure of Rs 20 lakh and the Madhya Pradesh Government the rest. An Urja Vikas Samiti comprising villagers and a forest official as secretary will run the project. Villages get electricity from a 10 KV gasifier. Billets are put into a furnace and the fire is ignited. The gasifier is connected to a generator. A steady supply of billets has been ensured and villagers have installed grain pulverizer.

Combined waste water treatment system for the treatment of distillation plant waste water in China
In Qingdao, an innovative combination of two-step anaerobic fermentation and subsequent aerobic treatment was selected. After pretreatment where the solids are separated off, the waste water is passed on to the anaerobic step. This process step contains one CSTR (completely stirred tank reactor) with 2,200 cubic metres capacity and a UASB (upflow anaerobic sludge blanket) reactor with 1,350 cubic metres capacity. After the anaerobic stage, the waste water to be treated is passed through a process separating liquid from solids into the aerobic process stage. In Qingdao, this consists of two SBRs (sequencing batch reactors) with 1,060 cubic metres capacity each. From this final stage, the purified waste water is then led into the receiving stream.

The biogas produced in the anaerobic stage is burned in a heating boiler and used for steam generation. Around 50% of the heat energy needed for the distillation plant can be produced using biogas. Separated solids and sludge are used as a fertiliser additive.

Parabolic trough power plant in Andalusia, Spain
There are three basic types of technology used in solar power plants-parabolic trough, solar tower, and dish-sterling systems. The central element of parabolic trough systems is the solar field that generates heat for conventional heat turbines. One solar field consists of many parallel rows of solar collectors arranged in a north-south direction leading from east to west according to the earth's rotation. The reflectors are parabolic mirrors consisting of extremely clear solver-coated glass. These concentrate the sun's rays by up to 80 times, focussing the heat on an absorber pipe in the middle of the row. This pipe transfers the heat energy-up to 400°C-and passes it on to a heat-carrying fluid inside the pipe. The steam generated by the sun's heat drives a turbine coupled with a generator for power generation.

Rural electrification using solar home systems (SHS) in Namibia
A German solar power company, has developed standard systems for both the state power systems and the private power supply companies. PowerCan solar power units are used as mobile systems, especially in project number two. The Premier Electric (PE) power supply company buys PowerCan systems and rents them to the end user. The PowerCan systems are installed by the power supplier involved on location. Customers draw power directly straight from the roof from the solar module. First, the system has to be activated with an electronic key. This robust system is similar to a common-or-garden plug, and can be bought at the local store and activated, for example, for a month. After the selected period has expired, the key can be reloaded again and again for future power use like a telephone card. With this prepayment, the customer automatically contributes to the costs of investment and maintenance.
