| 摘要 |
The present invention relates to methods or processes for utilising the waste streams from leather processing to produce energy by pyrolysing or gasifying the waste. It also relates to a system, in the form of a thermal energy plant which converts a portion of tannery waste to heat energy. In a preferred embodiment, the invention relates to a cyclical process whereby a portion of the waste effluent from leather manufacturing is converted to energy which can then be used in the leather making process. The thermal energy plant is closely associated with, and located near to, leather processing plants. This reduces the amount of carbon fuel required in the leather manufacturing process resulting in the production of leather which has used less carbon/fossil fuel in its manufacture than is used currently in leather production.Figure 4 |
