Best Ideas 2022 features all the nominated entries submitted under ‘Submit your Idea’ category. All the entries consist of innovative solutions or propositions for an enterprise that champions the Sustainable Development Goals. They can be on the conceptual, planning, or start-up stage.
Explain your idea in details:
We plan to build induction heated pyrolysis plants in cities with low waste plastic recycling rates. Instead of sending waste plastic to landfill or incinerators, waste plastic will be sent to pyrolysis plants and converted to fuel like diesel or gasoline. Diesel and gasoline can be consumed by local vehicles. Pyrolysis can accept a high variation of plastic types. Pyrolysis has been developed since the 70s. It has been used to decompose organic matter with heat and the absence of oxygen. The same technology can be used to decompose plastic. Major of the plastic we produced is not recycled, moreover, this plastic ends up polluting the ocean. The conventional pyrolysis process with a combustion heat source (oil, coal, or gas) is very energy intensive due to its low heat transfer coefficient. It is not economically feasible to invest in or operate commercial plastic pyrolysis without subsidy. Our purposed method "induction heated pyrolysis" can improve the heating efficiency can be increased from 50% to 85%. Plus, with the rapid heating property of induction heating, less dioxin is generated. The technology of pyrolysis is a way to effectively reverses the plastics production process, where hydrocarbons are used to create plastics. Instead, the process cracks the hydrocarbon chains within the plastics, to produce distilled fuels. We will use the existing recycling system and network.
Expected impact of your idea on sustainable development
Induction Heating pyrolysis has several advantages over the conventional heating methods of pyrolysis. Low Dioxin Generation High Heating Efficiency High tolerance on types of waste acceptance Low Dioxins Generation The incineration of plastic can generate a high level of dioxin due to the presence of oxygen in combustion. Indirect induction heating decomposes plastic waste in an anaerobic condition in which oxygen is absent. The rapid heating property of induction heating makes quick escalation through the low-temperature region( 200 to 300 C) which favors generating dioxin. The face of this project will make huge impacts in 3 fields respectively, namely: 1. ENVIRONMENTAL IMPACT: Reducing plastic waste as supply ort of the battle against ocean pollution and climate change. Reducing plastic waste from our environment by recycling thento to marketable products (Turning Trash to Treasure) Promoting the reduction of greenhouse gas emissions from plastic waste disposal. Community education on environmental conservatory through awareness campaigns. 2. SOCIAL IMPACT: Supporting local and rural communities with generated fuel as a source of electricity. To support individuals with fuel for domestic uses Jobs creation to the youth and women through CBOS who are involved ved in the collection and sorting and hence generating sustainable income by selling waste. Promoting education through creating conducive education for learning on the advantages and disadvantages of plastics waste. 3. ECONOMIC IMPACT: The facility will result in the diversion of waste plastic landfills while producing a cleaner fuel with the performance and quality of conventional diesel, but with a lower carbon footprint and low sulfur content. Reduce the high rate of fuel, diesel, and gasoline crisis in the country The fuel produced can be used directly as vehicle fuel without the need for further processing or adaptations to the engine. Recycling and waste collection fleet can benefit lower fuel cost for the operation
Plans for implementation and sustainability
An induction heated pyrolysis system with the capacity to treat 300 kg of waste plastic per day, may cost around USD 30 000 to $50 000. It can produce approximately 150 to 180L of diesel and ~40L of LPG and ~50kg of coal black. A small-scale plant only takes two workers to operate. It is a turn-key" system and easy to operate. However, it is not recommended since the scale is too small to be financially sustainable. A plant with a capacity of 30tons of waste plastic can be profitable. A pyrolysis plant with 30tons capacity costs around US$10M to $15 M to build. However, it can generate around USD$1M net profit a year. For such a plant, it only takes 4 to 7 staff to operate. Gas generated will be used toward generating electricity for the plant. I began to look at the solution to plastic waste and then it motivated me that I could be able to make petroleum components out of plastic waste. I realize the waste can be turned into treasure. If this project kicks off, there will be a percent increment in employment that will also help solve part of the unemployment rate in Ghana that will build the social-economic growth of families. Over the next 12 months, I am looking forward to building a fifty-ton pyrolysis plant. A US$10,000 will help build this pilot Pyrolysis plant which even if 1 ton of plastic can generate 800 liters of diesel. 1-tonne plastic can produce 800 liters of Diesel Therefore, 50 tons plant can produce 40,000 liters of Diesel
Yaw Afrim Gyebi, is a self-taught Documentary photographer, Photojournalist, Activist, and Humanitarian, born and raised in Kumasi in the Ashanti Region of Ghana, West Africa. He is also endowed with excellent organizational and communication skills and thrives in a fast-paced environment with the ability to multi-task that thrives on providing solid and essential backup to key positions and projects. A calm head and meticulous eye for detail ensure that all duties are carried out to the highest standards and in the allotted time frames. Being passionate about serving humanity, he founded FYDO Ghana, a non-profit organization based in Ghana that supports Education and Health and Empowers Women and Children in rural communities. He also founded the Ellis Cares Foundation which supports charities in underserved communities. He is an advocator for the Global Sustainable Goal 13, thus Climate Change, volunteering for Let's Do It Ghana, and in 2021 he was inducted by the Ghana Youth Environmental Movement as a Steering Member of the organization. Currently, he is a Country Mobilizer of Youth for Our Planet, a global movement based in Germany. Having been nominated and received the achievement award from the Humanitarian Award Global - Africa in 2021, he is willing to do more for his country and the world as he aims to make the world a better place. He started following his passion for photography. He expresses my feelings by telling stories of people living in marginalized communities in Africa. He called them "The Untold Stories". He helps international organizations, NGOs, aid agencies, and foundations tell their organizational stories, their mission, and the impact of their work through visual storytelling. He stands for change therefore, through photography I become a voice for those who need it.
