health care risk waste and general waste incinerator

We strive for a sustainable development therefore we are adopting a sustainable medical waste management system, which includes building a modern sustainable incinerator that will not only cater for our facility but also for the other facilities in the larger area of the region. We are aware that we need a  modern incinerator that will not burden the local people or the local environment even more. There are several different types of incinerators available (especially recommended to be built with local materials), which are cheap to build but are more harmful to people and environment.slaughterhouse in Afghanistan in ministry of agriculture.
