It examines both the environmental and economic comparisons of Hot Rocks against other fuels such as wood and coal. The major topics covered include: • The present situation in Christchurch, focussing on air pollution and its effects • Regulations that are in place, or proposed concerning domestic solid fuel burners • The method of production of Hot Rocks • A desktop correlation in order to estimate emission levels of Hot Rocks in burners meeting future requirements • A comparative study of combustion properties and economics between wood and Hot Rocks • Steps that need to be taken to ensure the viability of Hot Rocks as a manufactured fuel. There are advantages to be gained through utilising manufactured fuels such as Hot Rocks, produced from waste products for domestic purposes. Waste that would otherwise be sent to a landfill is recycled into a useful product. This product also compares favourably to natural alternatives such as wood and coal - Hot Rocks produce burning characteristic equal or superior to that of natural fuel alternatives. With the restrictions soon to be placed on coal and the proposed new regulations, public awareness on the issue of solid fuels has increased; hence it is an ideal time to enter the manufactured fuels market.
