Waste to Energy
Explain your idea in details:
Waste management is a big challenge in all major cities in Malawi as we are facing population increase due to urbanization as most people are moving to cities to seek for greener pastures which has resulted in these cities generating more tonnes of waste each day and due to budget constraints in our city councils only 30% of daily waste generated are collected and dumped at legal dumpsite. Lilongwe city which is Malawi's largest city with 988,338 people has a daily average of generating 500 tonnes of solid waste/day, 300 tonnes of bio solids (sewage sludge) while Blantyre a second largest city with 798746 people has an average of 400 tonnes/day solid waste and 240 tonnes/day of bio solids (sewage sludge). Waste management encompasses prevention, minimization, collection, transporting, processing, recycling or disposal, energy recovery and monitoring of waste materials. Waste is classified into different types depending on its source: municipal or household waste, industrial and hazardous, biomedical or hospital, construction and demolition, mining and electronic waste. It is also broadly categorized as solid and liquid waste. The main objective of Clean Energy Solutions is energy recovery from waste by using anaerobic digestion to produce biogas which will be burned in gas engines to produce electricity. Our activities will involve collecting 500-800 tonnes per day of municipal waste (crop, food residues) and sewage sludge and fed into anaerobic digester where biogas is produced which separated into methane, carbon dioxide and traces of gases. The composition of biogas is 55% methane, 44% carbon dioxide and 1% traces of other gases. Methane will be burned in CHP (Combined Heat & Power) engines to produce electricity. So energy recovery by CHP is an innovative approach of managing waste in Malawi. The byproduct of anaerobic digestion is a nutrient-rich fertilizer.
Expected impact of your idea on sustainable development
Unsatisfactory handling of waste could lead to contamination of soil, surface water, ground water and air. Thus, soil could be contaminated with toxic components; leachate from waste could pollute surface and ground water. Waste decomposition in illegal landfills creates emissions of greenhouse gases such methane and carbon dioxide these gases cause global warming. Clean Energy Solutions will satisfactory handle waste by energy recovery to produce clean energy and conserve contamination of soil, surface water, ground water and air. Our targets are reducing waste to landfill and illegal dumpsites such as open grounds, rivers and household pits. To ensure the target is achieved Clean Energy Solutions will increase the tonnage of waste required per day to be converted to energy. Our Key Performance Indicator is the Energy Output which is 10MW (Megawatts) for Blantyre & Lilongwe. Energy Output for CHP Plant depends on feedstock (fuel) to produce the energy which is waste, so the more the waste (food waste, sewage sludge) tonnage the more the gas (bio methane) to burn in CHP engines. Analysis shows that if biogas is used for the purpose of electricity and heat instead of fossil fuels, emissions of greenhouse gas decrease around 75-90%. Anaerobic fermentation and biogas production have some potential environmental advantages depending on the type of waste material, fuel and waste management systems.
Plans for implementation and sustainability
Our business model is energy recovery from residual waste. Our energy recovery from waste will be electricity which will be supplied to national grid under Independent Power Producer power purchase agreement with off-taker. Despite energy sales Clean Energy has heat and carbon dioxide which will sold to commercial industry and also nutrient-rich fertilizer which will be sold to farmers as organic fertilizer. Clean Energy started in implementing its plans in 2017 by conducting a pre-feasibility study for Waste to energy. The results were feedstock selection for the project, site selection, water availability, identifying Equipment Procurement Contractors, investment cost, Power Purchase Agreement with Off-taker, risk management and Plant or technology design. The results of the pre-feasibility study were built into our business proposal which was submitted to African Union in November 2017 under call for proposal and was shortlisted for possible funding and in January 2019 it was also shortlisted by Malawi Agricultural Industrial and Investment Corporation (MAIIC) under call for proposals and currently the project is at Feasibility study in order to finalize Power Purchase Agreement with off-taker. After this stage Clean Energy will proceed with project development. Clean Energy has collaborated PFAN, Micro Energy International, Biogas World and IRENA. Our sustainability plan is get feedstock contract from feedstock suppliers that is getting long term contract with City councils for waste collection, dumping and waste water treatment sludge collection. Getting a Power Purchase Agreement for a period enough to cover loan period and contracting a Biogas to Electricity plant operator who is skilled in our technology and run the operations.
