The reality is that incinerators don’t eliminate toxic substances, they concentrate them. The saying is: toxics in/toxics out. The heavy metals, mercury, lead and cadmium, don’t just disappear; they are basic elements not destroyed by burning. They are still present after incineration, only concentrated in the ash and released to the air from the stack. Of all the trash that enters the incinera...

The directive to close the dumpsite in Kisumu, Kenya has made search for alternative solid waste treatment and disposal technologies urgent. aim of this research is support decision-making process by analyzing multiple socioeconomic environmental parameters salient options. We used multi-criteria analysis assess compare anaerobic digestion, sanitary landfill, bioreactor incineration. Informed f...

Abstract Based on the global need to efficiently eliminate highly produced amounts of sewage sludge, alternative technologies are required be practically developed. Reduction sludge waste quantities with energy recovery is most important and modern practice, least possible impact environment. Appropriate for treating disposal currently considered: incineration, gasification pyrolysis. The main ...

Introduction: Incineration is one of the treatment methods for biomedical waste (BMW). It a source toxic air pollutant emission. The study aimed to compare haematological, cholesterolemic and clinical profile subjects exposed this pollution controls. Methods: This was comparative cross-sectional on 154 selected within 500 meters incineration sites solid controls, among new blood donors, matched...

This paper describes the application of life cycle assessment for evaluating various waste management options in Singapore, a small-island city state. The impact assessment method by SimaPro is carried out for comparing the potential environmental impacts of waste treatment options including landfilling, incineration, recycling, and composting. The inventory data include gases and leachate from...

Production of biogas through anaerobic digestion (AD) from the organic fraction of municipal solid waste (OFMSW) was compared to incineration of the waste. At the moment, almost all of the OFMSW in Singapore is incinerated. Three different scales of biogas plants were compared to incineration: one large-scale biogas plant that can treat half of all OFMSW in Singapore; one medium-scale biogas pl...

More than 100 million tonnes of municipal solid waste are incinerated worldwide every year. However, little is known about the fate of nanomaterials during incineration, even though the presence of engineered nanoparticles in waste is expected to grow. Here, we show that cerium oxide nanoparticles introduced into a full-scale waste incineration plant bind loosely to solid residues from the comb...

The management of medical waste is of great importance due to its potential environmental hazards and public health risks. In the past medical waste was often mixed with municipal solid waste and disposed of in residential waste landfills or improper treatment facilities (e.g. inadequately controlled incinerators) in Korea. In recent years, many efforts have been made by environmental regulator...

Waste plastics are low-value waste; thus, achieving high-value recycling is the most desirable goal. Scientific methods required to evaluate environmental benefits and support technology optimization market selection of waste-to-energy for plastics. This study selected catalytic cracking incineration power generation two typical examples waste energy technologies as research objects, establishe...
