Gasification Technology

In 2003 Eco-Valley became one of the first waste-to-energy facilities in the world to utilize Plasma Gasification technology on a commercial basis. Eco-Valley is located in Japan and has been successfully processing MSW with plasma for over seven years. The facility processes up to 220 tonnes-per day of MSW or up to 165 tonnes per day of a 50/50 mixture of MSW and auto shredder residue. The technology used at Eco-Valley is a result of a successful collaboration between Westinghouse Plasma Corp. and Hitachi Metals. With a first of kind facility like Eco-Valley, several operational challenges had to be overcome during and after commissioning. The objective of this paper is to share these operational experiences and learnings.

Gasification Technology

Great interest surrounds new technologies that are being offered as alternatives to conventional combustion of waste. Developers have identified the benefits of emerging technologies over existing technologies. In the years since many of today’s existing waste-to-energy (WTE) facilities were built in the United States, the technology required to process waste has improved dramatically in both environmental and operational performance. This technical paper presents a hypothetical study comparison of a generic WTE plant with plasma-arc gasification or other gasification technology. The case study represents a greenfield facility that would process 1000 TPD of MSW in two trains of 500 TPD each. The comparison includes the following elements: 1. General physical description of the facilities; 2. Emissions performance; 3. Byproduct and waste generation; and 4. Energy production. The comparison also discusses differential capital and operating costs, but does not attempt to establish these costs or compare economic feasibility.

Municipal solid waste (MSW) is becoming a concern as population in urban area is increasing. Several disposal methods (landfill and biochemical) have been used. However, waste to energy (WTE) particularly gasification technology is a potential technology for energy recovery. The system is used to convert biodegradable material into syngas under limited gasifying media. This study presents numerical analysis of producer gas for the two air paths in the hybrid fixed bed gasifier (HFBG). It was revealed that the optimum operating condition was achieved when the air ratio at the first air flow path (AIR1) was 0.3. Furthermore, the exergy efficiency of about 81.51% was   achieved.

The existence of electricity can encourage the improvement of the quality of life of the community. However, there are several problems with the provision of electricity in remote areas, including difficulties in delivering electrical equipment and fuel. One solution to solve this problem is implementing local waste utilization as fuel for power plants. This study aims to implement Waste to Energy using gasification technology on Tinggi Island, South Bangka. The methods used in this research are to calculate the potential amount of waste, design the equipment specification, make the supporting facilities, and do a testing experiment. Due to the low waste potential in Tinggi Island, local communities’ waste processing is carried out in Toboali. The waste processing stages are sorting, fermentation, chopping, drying, and pressing. The waste pellets from Toboali are sent to the powerhouse in Tinggi Island. From the performance and reliability test in the electrical side, it can be concluded that the voltage and the frequency generated is stable and within the safe limits according to Regulation of the Minister of Energy and Mineral Resources No. 03 of 2007. The consumption of waste pellets needed to generate electricity during the reliability test (75% loading) is ten kg/45 minutes. Through the continuous implementation of waste to energy, Tinggi Island can be electrified all day long and solve the waste problem.

Conversion Technology

Countless proposals for conversion technologies applied to municipal solid waste (MSW), such as gasification, many of which include mechanical processing of the MSW prior to the thermal conversion steps, have generated significant interest and press over the past few years. Many community groups and local officials are being pressured by developers to view these technologies as better and more politically acceptable alternatives to mass burn waste-to-energy facilities. From a historical perspective, most (but not all) of the basic technologies being promoted today are not new, but are variations of technologies that were evaluated and tested during the 1970s for use in processing and converting MSW. This paper presents overviews and several case studies of the MSW conversion technologies that were developed and tested during the 1970s including MSW processing and gasification technologies, and sets forth: • Lessons learned from those experiments. • Based upon the lessons learned, recommended rules of engagement for those contemplating evaluation or use of a processing and/or conversion technology. • A practical application of the above lessons learned and rules of engagement to the plasma arc gasification technology currently being promoted by a number of developers. The contents of this paper should be carefully considered by anyone contemplating the merits and feasibility of any MSW processing and/or conversion technology being promoted today or in the future.

Waste management in the United States presently has the following major three dimensions: Sanitary landfills, recycling, waste to energy predominantly based on the technologies of mass bum technology or refuse derived fuel. These three dimensions have undergone significant evolution during the past three decades. The design of sanitary landfills has evolved to include environmental protection features such as bottom liners, leachate collection systems and landfill gas management systems. Material recycling programs, many based on materials recycling facilities, have become more prevalent. Approximately 100 operating waste to energy facilities (“Facilities”) now exist in the United States. Improvements in the air pollution control systems incorporated in the Facilities have significantly lowered their air emissions. A fourth dimension, waste gasification technology, is evolving as a viable component of a waste management system and the hydrogen energy economy.

The increasing volume and complexity of waste associated with the modern economy as due to the ranging population, is posing a serious risk to ecosystems and human health. Every year, an estimated 11.2 billion tonnes of solid waste is collected worldwide and decay of the organic proportion of solid waste is contributing about 5 per cent of global greenhouse gas emissions (UNEP). Poor waste management - ranging from non-existing collection systems to ineffective disposal causes air pollution, water and soil contamination. Open and unsanitary landfills contribute to contamination of drinking water and can cause infection and transmit diseases. The dispersal of debris pollutes ecosystems and dangerous substances from waste or garbage puts a strain on the health of urban dwellers and the environment. India, being second most populated country of the world that too with the lesser land area comparatively, faces major environmental challenges associated with waste generation and inadequate waste collection, transport, treatment and disposal. Population explosion, coupled with improved life style of people, results in increased generation of solid wastes in urban as well as rural areas of the country. The challenges and barriers are significant, but so are the opportunities. A priority is to move from reliance on waste dumps that offer no environmental protection, to waste management systems that retain useful resources within the economy [2]. Waste segregation at source and use of specialized waste processing facilities to separate recyclable materials has a key role. Disposal of residual waste after extraction of material resources needs engineered landfill sites and/or investment in waste-to-energy facilities. This study focusses on the minimization of the waste and gives the brief about the various initiations for proper waste management system. Hence moving towards the alternatives is the way to deal with these basic problems. This paper outlines various advances in the area of waste management. It focuses on current practices related to waste management initiatives taken by India. The purpose of this article put a light on various initiatives in the country and locates the scope for improvement in the management of waste which will also clean up the unemployment.
