Did you know that plasterboard and breeze blocks are made from the waste products of coal-fired power stations? Their production diverts thousands of tonnes of material from landfill. Breeze blocks are made from the ‘clinker’ and fly ash which are what is left after the burning of the coal dust.
Plasterboard is made of gypsum which is the by-product of the removal of the acid from the power stations smoke. The lime to remove the sulphur often arrives by train, then the gypsum is used in a nearby factory to make plasterboard.
