Waste to Energy

We believe in energy recovery. Taking it one step forward, we have developed facilities that enable us to convert select waste into reusable energy. We are able to convert liquid waste into synthetic fuels through a process called fuels blending and solid waste into AFR (Alternative Fuel and Raw Materials).

Waste materials with a calorific value, are carefully blended, following stringent controls on the blending process, to ensure no adverse chemical reactions. These blended materials are manufactured into an alternative fuel, which is delivered by PPLI under strict control procedures, to a third party user and processor, a cement kiln, located closed by.

The high temperature (1,200 – 1,400°C) and long retention times inside a cement kiln ensure that all organic waste is completely destroyed, while being utilized as alternative fuel and/or alternative raw materials. The alternative fuel is used to displace virgin fossil fuels such as coal and oil, in the manufacture of cement, hence creating an enviromentally-beneficial use for waste.

This energy recovery facilities have been in operation since 1994 and are the only fully-permitted facilities in Indonesia.
