Private sector firms, especially the sugar companies, were challenged to seize the opportunities for investment in such blending. The government set the policy framework and provided the incentives and infrastructure, within which the private sector could respond. The leading investor was Press Corporation Limited, a publicly listed company incorporated in Malawi. The first ethanol plant was built by Press Corporation in 1982, with a final blending ratio of 10 per cent, and in 2004, they opened a second plant, with a combined total capacity of 18 million litres a year.
