The report is focused on mapping pollution by persistent organic pollutants (POPs) in villages of Karawang Regency, West Java, at sites affected by using plastic and rubber waste (including used tires) as fuel in lime kilns. This study analyzed ash samples from waste incineration, soil samples, and eggs from free-range chickens near the lime kiln.

Plastic production, meanwhile, is projected to double within 20 years. Such thinking is naive, said Axel Pieters, chief executive of Geocycle, the waste-management arm of Holcim Group, one of the world's largest cement makers and partner with Nestle, Unilever, and Coca-Cola in plastic-fuel ventures.

Here, a BUMDES (village owned enterprise) converted MSW to Refuse Derived Fuel (RDF) in the area around a cement plant in Cirebon, Indonesia. The RDF that is produced is used as a partial substitutiton fuels for the kiln in the cement industry.

Waste with a high heating value can be used as a fuel source for the kiln itself, or for the secondary combustion chamber to further improve the sustainability of the operation. Complete Rotary Kiln Incineration (RKI) Systems. Today's rotary kiln incinerators are highly efficient and designed to comply with emissions regulations.

The conversion of plastic waste to energy product is a promising solution to both energy shortage and environment pollution.
