A Study on Incineration from the Wastages of Footwear Industries in Bangladesh

In Bangladesh footwear industries are a promising sector for rapid increase of export earnings. There are about 5000 small, medium and large scale footwear industries in Bangladesh. The production of Energy from Waste is not a new concept, though it is a field that requires serious attention. Leather, footwear industries are producing a bulk amount of scrape material, in this project we tried to recover energy from waste leather and allied materials through Incineration, the combustion of organic material such as waste with energy to recover the energy. Leather is one of the most widely traded commodities in the world. The leather and Footwear industry plays a prominent role in the world’s economy, with an estimated global trade value of approximately US$100 billion per year. Leather raw materials have increasingly become available in the developing world. Now, more than half of the world supply of leather raw material comes from the developing world and, increasingly, those countries with large supplies are seeking to process them through to finished leather articles. This report assessed the prospects of the leather and footwear industry in the coming decade in Bangladesh & so about the estimated wastage. In its attempt to provide a thorough picture of the Footwear sector, the project work tried to utilize the waste in brick field and it was found that using leather wastage as a fuel, we can save our valuable gas, coal without deforming the final quality of Brick in brick field. We can substitute coal by wastes leather for burning purpose. In the mean time we can supply half of coal to burn the bricks and on the same time we can give wastes leather in the burning chamber of brick field. Because in the experiment of Bomb Calorimeter we have found the calorific value of Oily Nubuck Leather(dried) 6096.997* which is equivalent to coal. 4 (Four) Ton Coal is required per day when the traditional Brick Field run its operation in winter. Total Production capacity per day=40,000 pieces of Brick. The amount of coal per Ton price =10,000 BDT. If we use leather wastes as fuel the production cost will be minimized in Brick field and it will be more ecofriendly. As we have the power crisis so it will be great achievement if we are able to get renewable energy such as gas, heat, electricity etc. as a byproduct.
