Abstract

Many developing countries, including African ones, look forward to developing strong integrated textile industries to add value to already-available raw materials. Dyeing and finishing activities are, however, energy-intensive. In many cases, these depend on imported fossil fuels. By turning to heat recovery, significant cost savings can be achieved improving profitability and competitiveness. The techniques and technologies of heat recovery from waste water and exhaust air are analysed. Experiences prove that in most cases heat recovery requires low investment and has a low payback of normally less than 2 years. The case of the Mauritian dyeing and finishing industry is highlighted, including the possible use of a low-cost heat recovery unit made from indigenous resources.
