TRAMO - Wask Group

History and ownership Of TRAMO Services

While studying for his Bachelor’s degree at the Kwame Nkrumah University of Science and Technology, William Anarfi-Sarpong, in pursuing his passion to see a much cleaner environment in and around campus – KNUST, founded the Trash Management and Recycling Organisation (TRAMO). As a group registered on campus, TRAMO became a house-hold brand, holding public awareness programs on proper waste disposal methods with lots of emphasis on waste recycle. The group also assisted in providing litter bins at vantage points on campus. In 2013, its founder was awarded the nationwide Innovator of the year at the KNUST NUGS -Vice Chancellor’s Excellence Award.
The current form of the organisation took shape in 2012 after it has been registered as a limited liability company under the Ghana Company Act – 1963 (Act 917). The company is 100% Ghanaian owned and currently operates from both its Accra and Ashanti Regional offices, with the set vision of transforming Africa’s waste management system. TRAMO partners other local and international organisations with business interests in waste recycle, public policy analysis, sanitation research and fronting both technical and financial investments to realise Ghana’s sanitation ambitions.


Our Organisational Strategy
Vision Statement:
The Vision of TRAMO is to become the leading waste management organisation in Africa well versed in promoting global environmental responsibility and making society more effective in dealing with the menace of environmental pollution through accessible technology.
Mission Statement:
Our mission is to deploy the available capital and technology to transform waste into useful resources and offer outstanding satisfaction to the needs of homes and businesses in Ghana.

Our Current Business position
We are currently positioned to invest and create value from both solid and liquid waste through our flagship biogas processing units. The company has in the past operated in the areas of waste collection from household, hotels and other private companies with the emphasis on recycling waste to provide environmentally friendly and cost effective resources for households, businesses, educational institutions. Over the last two years, TRAMO also took up the agenda to lead the industry to realise that Ghana’s plastic waste is converted into Plastic Pavement and Roofing Sheets.
TRAMO currently sees this Biogas Plant idea as its next big move for the sanitation business. While on a small scale, its portable biogas system is catching up, among businesses and hote

ls in and around Kumasi, the company anticipates that with the right partnership, large digesters of 1380 cubic metres in size can be developed for use in districts, educational institutions and even more portable digesters can be deployed. The company sees a great competitive advantage with this project due to the vast utility of its end-products. With the current technology under consideration, the entire cycle of digestion could produce liquid fertilizer, clean water and biogas that could be used for cooking and to power a generator for lighting and powering appliances.
Summary of Past Achievements
1. Launching of the Ghana Go Green Campaign to create massive and intensive public awareness on the dangers of poor sanitation.
2. Establishment of Waste Sanitation Clubs in various second cycle and tertiary institutions
3. Waste sorting education with United States Peace Corps
4. Distribution of dustbins to the halls of residences at KNUST
5. Waste pick-up packaging and sale of recyclable materials
6. Installation of portable biogas system in homes and hotels
The Design of the TRAMO Biogas Digester
The proposed 260m3 and 1380 m3 size Assembly Biogas Plant for senior high schools and university have been designed to require less effort during assembly. It has great aesthetics; surface-mounted and would hardly require earthwork and heavy construction. The system is highly efficient and comes with hollow sunlight sheet green house and pad for insulation and heating. It is specially designed to digest large amount of organic waste into biogas and energy to generate electricity that can be used in the districts.
The system is composed of a membrane digester with a gas storage bag combined in one, a stainless steel sink, a stainless steel outlet, a biogas filter and a biogas booster pump. The membrane of the digester has the characteristics of anti-aging, acid and alkali resistant and rodent resistance. The inlet and outlet of the digesters are also made of stainless steel and the metal supporting frame is made of galvanized iron. There is high guarantee of safety as each digester is installed with a pressure releaser that receives inflow of biogas when the pressure in the digester is too high. Also the biogas fermentation process happens in the sealed membrane digester after which biogas is collected and desulfurised making it totally odourless.
The specific design TRAMO is proposing is an original innovation of the Shenzhen Puxin Science and Technology Company Limited in China. The Puxin design is popular for its unique incorporation of some of the best features of the conventional digester designs. What would become the TRAMO Biogas Digester in Ghana is a hydraulic pressure biogas digester that comes with a fermentation tank, and a digester outlet cover. Digestion would go through 6 main phases: The pre-treatment of organic material, the initial digestion, circulation, second digestion and then finally dehydration and desulfurization to reduce the odour. The 1380m3 unit digester is able to digest a maximum of 12.5 tonnes of food waste, 22.5 tonnes of food manure, 30 tonnes of cow manure, 13.5 tonnes of chicken manure, 17 tonnes of human manure or 32.5 tonnes of vegetables. In terms of output, the 1038 m3 digester can produce a total of 1000m3 of biogas per day and 500m3 of organic liquid fertilizer. It can also produce 1500KWH of electricity per day. Whereas the 260m3 can digest 2.5 tonnes of food waste, 6 tonnes of cow manure, 2.7 tonnes of chicken digester, 3.4 tonnes of human manure and 6.5 tonnes of vegetables. It can also produce 200 m3 of biogas and 300KWh of electricity.
