API Holdings – API Holdings Ltd was founded in 2008 with the primary objective of providing high quality, independent advice, and support services to stakeholders and organisations involved in sustainable development and renewable energy projects.
A key component of the company is the scoping and feasibility expertise and processes that offer informed and sound advice to clients at a project specific level. API provides expert technical, environmental, and planning support advice to utilities, developers, industry, API communities, governmental, and the public sector throughout the entire project life-cycle from the initial feasibility stages, through to implementation, as well as completed and ongoing operations. One of the company's key areas of expertise is in Waste to Energy (WtE) - the process of creating energy in the form of electricity from the pyrolysis and gasification of a feedstock of various waste arising’s.
The proposed technologies can produce both electricity and heat which can either be used locally or put directly into the grid system. The processes create a clean gas from the waste which can be either transported as a gas or used within a reciprocal engine generator. Heat can be converted via an exchanger for steam creation or refrigeration/cooling systems dependent on local requirements. The plants are proven and are known as best available technology (BAT), that is clean with low emissions, operating well below the required EU and US emission regulations and requirements. The plants are modular and can be designed to handle the local waste arising’s. This can range from 10,000 tpa up to 120,000 tpa on any given two hectare site. The optimum site and waste level of conversion is 60,000 tpa which will give a consistent output of 4 MWh of electricity or up to 15 MWh of gas depending on requirements, and a minimum of 8,500 operating hours per annum. The plants are designed to dispose of waste in a “green” manner producing a more environmentally friendly energy source, as well as hot water, sterilized recyclable glass, metals, and the potential sale of sterilized ash. The pyrolysis residue generated from the plant can also be used to compliment animal feedstock, thus adding a fertilizer component to the Plant. The insert residue can be used to produce soil fertiliser.
Other applications of the residue include road aggregate (rocks and sand), brick making (low cement type brick stocks), and imitation wood substitutes when combined with resin. Plants of this nature could recoup their initial investment within a 5 year period, depending on the size of the plant and how efficiently it is run. The plants require low maintenance. Houses and business would have the electricity they so desperately need and the government would be disposing waste in a significantly cleaner manner. This essentially will have a two pronged effect, as the technologies employed will produce vital electricity, as well help mitigate the generation of waste, and thus form an important part of the overall projects waste management plan. Informal settlements, where there is disease due to the pile up of waste, would begin to look cleaner as the residents would be encouraged to drop off their waste in order for them to receive electricity for a reduced price. Due to the low emissions, these plants could also earn additional revenue from international incentive schemes such as carbon finance, also known as carbon credits, through the Clean Development Mechanism (CDM) under the United Nations. Since the plant is modular, it can be increased and can accept more than 60,000 tons of waste which would also increase the electricity supply.
