Near Future

<p>The landfill gas (LFG) produced from the existing landfill site in Heraklion city, Crete island, Greece, is not currently exploited to its full potential. It could however be exploited for power generation and/or combined heat and power (CHP) production in near future by fully unlocking its energy production potential of the gas generated from the landfill site. This gas (LFG) could feed a 1.6 MW<sub>el</sub> power plant corresponding to the 0.42% of the annually consumed electricity in Crete. The LFG utilization for power generation and CHP production has been studied, and the economics of three energy production scenarios have been calculated. An initial capital investment of 2.4 to 3.2 M €, with payback times (PBT) of approximately 3.5 to 6 years and Net Present Values (NPV) ranging between 2 to 6 M € have been calculated. These values prove the profitability of the attempt of bioenergy production from the biogas produced from the existing landfill site in Heraklion city, Crete. Based on the current economic situation of the country, any similar initiative could positively contribute to strengthening the economy of local community and as a result the country, offering several other socioeconomic benefits like e.g. waste minimization, creation of new job positions etc. by increasing, at the same time, the Renewable Energy Sources (RES) share in energy production sector etc. Apart from the favorable economics of the proposed waste to energy production scheme, all the additional environmental and social benefits make the attempt of a near future exploitation of the landfill gas produced in Heraklion, an attractive short term alternative for waste to bio-energy production.</p>

Potential opportunities for electric power generation from landfill gas (LFG) utilization were estimated for the second largest landfill site in Bulgaria, situated near the city of Plovdiv. The work performed was based on detailed analysis of experimentally obtained and model-predicted features of the ?Tsalapitsa? landfill site. The study presents a short description of the site, the global characteristics of the disposed municipal solid waste, and the experimentally obtained methane composition of the LFG. Based on the above described observations, the potential for LFG recovery at ?Tsalapitsa? was determined, together with that for electric power generation for the next 25 years. A set of recommendations was then developed regarding the parameters required for the installation of electric power generation from LFG in Plovdiv.

Distributed Power Generation

A demonstration system has been developed intending to meet the California Energy Commission’s primary goal of improving California’s electric energy cost/value by providing a low-cost, high-efficiency distributed power generation system that operates on landfill gas as fuel. The project team led by Makel Engineering, Inc. includes UC Berkeley, CSU Chico and the Butte County Public Works Department. The team has developed a reliable, multi-cylinder Homogeneous Charge Compression Ignition (HCCI) engine by converting a Caterpillar 3116, 6.6 liter diesel engine to operate in HCCI mode. This engine utilizes a simple and robust thermal control system. Typically, HCCI engines are based on standard diesel engine designs with reduced complexity and cost based on the well known principles of engine dynamics. Coupled to an induction generator, this HCCI genset allows for simplified power grid connection. Testing with this HCCI genset allowed for the development of a control system to maintain optimal the inlet temperature and equivalence ratio. A brake thermal efficiency of 35.0% was achieved while producing less than 10.0 ppm of NOx and 30 kW of electrical power. Less than 5.0 ppm of NOx was recorded with a slightly lower brake thermal efficiency. Tests were conducted with both natural gas and simulated landfill gas as a fuel source. This demonstration system has shown that landfill gas fueled Homogeneous Charge Compression Ignition engine technology is a viable technology for distributed power generation.

Gaseous Hydrocarbons

A new landfill gas-based reforming catalytic processing system for the conversion of gaseous hydrocarbons, such as incoming methane to hydrogen and carbon oxide mixtures, is described and analyzed. The exit synthesis gas (syn-gas) is fed to power effectively high-temperature fuel cells such as SOFC types for combined efficient electricity generation. The current research work is also referred on the description and design aspects of permreactors (permeable reformers) carrying the same type of landfill gas-reforming reactions. Membrane reactors is a new technology that can be applied efficiently in such systems. Membrane reactors seem to perform better than the nonmembrane traditional reactors. The aim of this research includes turnkey system and process development for the landfill-based power generation and fuel cell industries. Also, a discussion of the efficient utilization of landfill and waste type resources for combined green-type/renewable power generation with increased processing capacity and efficiency via fuel cell systems is taking place. Moreover, pollution reduction is an additional design consideration in the current catalytic processors fuel cell cycles.

Rising energy costs, increasing landfill prices and the environmental imperative to reduce atmospheric emissions of fossil CO2 are all compelling medium and large energy users throughout Australia to consider decentralised onsite power generation options. In addition to the rollout of household and community-scale photovoltaic (PV) and wind, waste-to-energy technologies such as landfill gas and biogas-based power plant are now well established in Australia. However, various other waste-to-energy technologies, operating elsewhere, have yet to take off. This presentation provided an overview of waste to- energy processes, including examples of currently operating commercial processes as well as recent research to highlight the interesting mix of processes and economics that make up the waste-to-energy landscape.

Reuse Options

The professional management of landfills during operation and after landfill capping is an important task to prevent environmental impacts. Landfill maintenance after closure can become economically favourable if landfill sites can be reused. Several approaches and experiences for reuse of capped landfills exist for example in livestock farming or installation and operation of solar power plants. Also the utilization for spare time activities after green capping and recreation or the industrial reuse for the development of a waste utilization plant is a common practice in Europe. The feasibility of reuse options depend on the site conditions including size and location of the landfill, the climatic conditions and the interests of the involved stakeholders. For the urban landfill site Gò Cát in Ho Chi Minh City (HCMC) experts from Germany and Vietnam developed a variant assessment for the preferred reuse options. One of three investigated options is considering the reuse of the landfill site for the development of a biomass utilization plant. In terms of the above described approach for Gò Cát the landfill operator is strongly involved in the landfill closure and long term maintenance works (leachate treatment, landfill gas utilization). Moreover, the operator can reuse the landfill site for an additional or new business. The design and operation criteria for the biomass utilization plant and best practice examples are presented. Beside the economic evaluation results of water and landfill gas balance will be discussed.
