Waste management is a critical issue for most cities as a result of the huge generation of mountains of waste stemming from increases in urban populations over the last few decades, coupled with access to consumer goods by a fast-growing middle class. And waste generation is expected to increase rapidly in the future. City authorities are therefore faced with the challenge of managing urban waste with limited resources at their disposal. Unsustainable waste management has adverse consequences on the environment including the breeding of mosquito and related diseases, emission of obnoxious odours and methane, and flooding caused by choked drainage systems. These waste-related problems are not uncommon in most cities and city authorities are seeking sustainable waste-management solutions. Indeed, unraveling sustainable solutions for efficient waste management is one of the top priorities for developing countries.
Access to energy and electricity in particular, is an indispensable condition to develop economic activities and to improve the quality of life. The use of electricity is a key factor to make agricultural and industrial processes more efficient. Electricity is needed for households (cooking, lighting, refrigeration, and home-based activities) but is also needed for essential facilities such as hospitals, schools, and for industry. Energy consumption and energy access is an important issue directly related to income and poverty, as limited and unreliable energy access translates into poverty, limited employment opportunity and poor economic performance, and it is a major impediment to economic growth. Because Draig optimise the combustion to 100% even when burning City Waste, DRAIG are able to offer solutions that meet and exceed the World standards for clean emmissions.
As cities rapidly grow, so does the amount of waste that they generate. Changing human consumption patterns and the changing structure of economic activity generate various types of waste that must be appropriately managed to ensure sustainable development and a decent standard of living for all urban residents. In low-income countries, in particular, rapid urban growth is putting extraordinary pressure on limited urban resources for the provision of these essential basic services, further straining capacity in urban management.
Furthermore, inappropriate policies have contributed to the growth of life- and health-threatening slums, where urban waste management services are often woefully inadequate. Indeed, there is perhaps no area where the capacity to manage urban change is more urgent and more challenging than in informal settlements and slums. Poverty, social and economic exclusion, and the lack of affordable housing constrain the habitat choices of hundreds of millions of people in Africa.
Policy makers have not responded appropriately, often denying service provision to these settlements. As a result, 62% of urban populations in Sub-Saharan Africa live in slum areas dominated by uncontrolled informal spatial developments, most often located in environmentally fragile areas, and without access to basic services such as water, sanitation, energy and transport and waste management systems.
DRAIG's Pyrolysis Plant is the Solution to City Waste Problems
Pyrolysis of waste is pertinent in the context of the energy crisis. Development work has been done with a 100 tonne/ day plant.
The process is self - suflicient and regenerative.
A valuable byproduct is tar oil, which is a substitute for furnace oil. Char can be used as a domestic fuel or fertiliser production.
In the backdrop of energy crisis and investigations conducted, it is economically viable to employ pyrolysis of MSW (Municipal Solid Waste) and industrial waste in the metropolitan cities in Africa.
Draig's solution is viable because it not only converts garbage to solid, liquid and gaseous fuels but produces valuable chemical and other feed stocks for
downstream processing , as well as producing electricity.
For Example a 2000 tonne/day of city garbage, when subjected to pyrolysis will yield 600 tonnes of char, 30 tonnes each of glass and metal and 80000 litres of oil. Therefore, recycling of municipal solid waste by the pyrolysis route is not only an answer to the waste disposal problem but an answer to the energy crisis also.

Draig's Community Power Station can operate on Anthracite, coal, lignites, wood, wood chips, pelletised wood, waste derived fuels, bio-fuels or bamboo.
The DRAIG Energy Centre doesn't need a large water source when generating electricity, therefore it has no need to be sited by water, or have a large dam constructed by the side of the power station.
Efficient combustion relies heavily on controlling the excess air going into the combustion chamber. Too much and you have free oxygen that can combine with nitrogen or sulphur, making nasty gases. Getting the oxygen content right is the job of Draig's patented computer system. 97-98% combustion efficiency together with Carbon Capture technology means almost ZERO harmful gases.
DRAIG Ultra-Low emission burners together with Karbonyx Zero emission technology, means DRAIG will soon be able to guarantee 'ZERO' Harmful emissions go to the atmosphere.
A DRAIG Energy Centre needs no major water source to operate, it can be sited in the most unlikely and harsh environments. So long as there is an available fuel source locally, the Energy Centre will produce electricity. Which means the Draig Energy Centre can be located at the end of a transmission line, where power is needed.
The DRAIG Energy centre has been designed to plug together in 50MWe modules. Therefore the sizing of the power station is easy as for 200MWe you need 4 modules. These are delivered to site in containers that are simply plugged together. Everything is pre-tested before it leaves our factory, we deliver a power station to site that produce electricity immediately.
DRAIG have been providing combustion equipment and burner solutions across the World since 1951. The basic principles have remained the same whilst the designs have been modernised to deal with 21st Century fuel source requirements. Modern solutions to modern problems.
Growing Bamboo around each power station can provide hundreds of new employment opportunities in each area.
