According to the World Bank, the world’s cities generated 2.01 billion tonnes of solid waste in 2016 and this is expected to grow by 70% to 3.4 billion by 2050 on the back of rising population numbers. By turning plastic waste into a “commodity”, our projects will play an important role in making a significant contribution towards the advancement of clean energy generation.

South Africa

Under Sustineri Energy, a joint venture in which Kibo holds 65% and the balance of 35% is held by Industrial Green Energy Solutions PTY LTD, Kibo is building a portfolio of seven waste to energy projects in South Africa. The JV will own and operate these facilities, once constructed and commissioned.

Using pyrolysis technology, these projects will process non-recyclable plastics to generate alternative energy to supply industrial users.

These projects will build up to a generating target of c.50 MW. The first project in development:

2.7 MW Plastic to Syngas Power Plant

The JV has entered into a 10-year take-or-pay conditional Power Purchase Agreement (`PPA’) to generate baseload electricity from a 2.7 MW plastic-to-syngas power plant.

The project will provide the Client with cleaner electricity, by making use of a high temperature pyrolysis process, where selected non-recyclable plastics will undergo thermal degradation to produce high quality syngas, which will in turn feed gas engines to generate both electricity and heat energy. Additionally, there is potential to sell the heat energy generated as a by-product from the gas engines directly to customers inside the industrial park.

The plant will be constructed, commissioned and operated for an Industrial Business Park Developer in Gauteng, South Africa.

The project represents an attractive investment case with anticipated low-risk IRRs between 11% – 14% p/a. Refer to RNS 451931 dated 14th February 2022 on the latest update regarding this project.

United Kingdom

Waste-to-Energy is one of the circular economy solutions that can deliver economic, social, and environmental co-benefits by tackling widespread chronic waste problems while reducing emissions and creating alternative, sustainable power for the UK.


Southport is a new waste-to-fuels (‘WTF’) plant by Shankley Biogas Ltd, a 100%-owned subsidiary of Kibo Energy, with a projected capital expenditure of c. £46 million. Located in the county of Merseyside, north-west of England on Southport’s largest industrial estate, it is a brownfield site that lies 40 minutes away from three major motorways — M6, M57 an M58 — providing access to most major hubs in the UK. It is bounded to the south by Southport’s main 132 KV sub-station and is 300 metres from the Southport main incoming gas main and the town’s main gas distribution network.

The plant is in RIBA stage 2/3 and will supply the local grid with bio-methane (green gas) and power. Planning permission has been granted for the site, with the construction of the plant expected to commence in Q2 2023 and the plant expected to be operational by Q34 2024.

The plant will be developed using anaerobic digestion (‘AD’) technology, a proven technology used in more than 10,000 plants worldwide (650 of which are in the UK alone). The plant will also include a 10 MW installed capacity power-generation unit to enhance plant profitability.
