Government funds for renewable energy
A recent decision by the government to allocate funds for renewable energy is indeed an excellent and very rational one for which it deserves appreciation from us. As reported in the media, the fund which was initially meant for some other purposes, will be diverted for financing solar energy, bio-gas and effluent treatment plants. This is the right way for the country to accelerate the progress towards providing energy (electricity), without the recurring need for importing solid and liquid fuel, usually needed for producing electricity.
Regarding effluent treatment plants, this writer feels that we should go for at least one or two projects for recovering methane gas and solid fuel briquettes that can be easily produced from solid human waste. The plant except for the compressor for pumping the methane gas, can be made from locally rolled plates and fabricated steel pipes available locally at the re-rolling mills. For the solid briquettes, the raw material will be the residue left over and removed periodically from the bio-gas plants producing methane from solid human waste. This residue, mixed with saw mill dust, wood shavings and timber wastage, mixed with used lubricants and waste grease, coal dust etc. makes excellent coal like solid briquettes, and can be easily and comfortably handled than the loading, transport handling and breaking of imported bulk coke and coal at coal yards and all across the transport handling phases.
In this writer’s considered opinion and based on what he saw in details in Thailand, over twelve years back, we can implement it here in Bangladesh. In Thailand, they have stopped almost total import of liquid and solid fuel, and substituted it with methane gas produced by the solid human waste and fuel briquettes from the leftover solid residue of methane gas production, both in urban and rural areas, where people use fuel for cooking and small workshops and industries are located there. They now import only lubricants and aviation fuel. We should follow the same path to cut down our import of coal and liquid fuel in the national interest.
