Organics Ltd provides engineering equipment that falls into two main categories: Environmental Protection and Renewable Energy. Their services include low emission flare systems, of which they have many hundreds of installation around the world, odor control, landfill gas extraction and utilisation, anaerobic digestion systems and advanced thermal processing (pyrolysis and gasification). They specialize in field and landfill engineering in particular.
Organics offers the following services for Waste to Energy systems.
It is often the case that staff responsible for a landfill site may not wish to have key management effort diverted from core business to such peripheral activities. Passing such a responsibility to a specialist company makes it possible to remove the threat of penalties accruing from system failures as well as facilitating the establishment of a clear financial forecast as a basis for management of the issues involved.
Organics offers a range of options under this heading, from straight leasing and lease-purchase to Build Own and Operate (BOO), Build Own Operate and Transfer (BOOT) and Design, Build and Operate (DBO).
Gasification with air produces a low-Btu gas, with a heating value about one-fifth that of natural gas. Indirectly heated gasification and oxygen-blown gasification produces a medium-Btu gas, with heating values as much as one-half that of natural gas. The product gas is suitable for fuelling advanced power systems that require clean, gaseous fuels.
Organics has developed and proven its own in-house technology for the efficient gasification of varied biomass streams. Of particular interest is Municipal Solid Waste, although many types of organic waste are suitable for use with this technology to produce energy.
Organics is able to offer a number of anaerobic digester designs for differing feedstocks and varied locations. Primary options are the Covered Lagoon Anaerobic Reactor (CLAR), the Continuously Mixed Anaerobic Tank Reactor (CMATR) and the Upflow Anaerobic Sludge Reactor (UASB).
Each technology has its optimum point of application. The CLAR has a large footprint but is robust and reliable. The UASB has a much smaller footprint but is high rate and needs considerably more attention for successful operation. The CMATR is a possible compromise, where land space is limlited and high levels of supevision are not possible.
Municipal Solid Waste to Electricity Through Gasification.
The system offered here for the commercial implementation of a waste-to-energy strategy is based upon the following process stages:
Pyrolysis is the use of heat to break down biomass into its constituent gaseous components in the absence of combustion. The pyrolysis technology offered by Organics involves the use of heat in the complete absence of air. Without air combustion is not possible. The resultant reactions are therefore clean and complete, leading to a maximisation of power production in the form of Volatile Organic Carbons. These are the re-formed biomass constituent components now present as a gas.
With the complete absence of air, toxic products of partial combustion, such as dioxins and furans, cannot be formed.
GALFADTM is an integrated waste disposal system designed to maximise energy recovery from unsorted municipal solid waste. The simple objective is to use appropriate conversion technology for each type of waste.
