What are the 4 R’s?

Recycle: transforms materials that would otherwise become waste into valuable resources. In addition, it generates a host of environmental, financial, and social benefits. Materials are collected, separated and sent to facilities that can process them into new materials or products.

Reduce: Waste prevention, or "source reduction," means consuming and throwing away less. Source reduction actually prevents the generation of waste in the first place, so it is the most preferred method of waste management and goes a long way toward protecting the environment.

Reuse: Reusing items by repairing them, donating them to community groups, or selling them also reduces waste. Reusing products, when possible, is even better than recycling because the item does not need to be reprocessed before it can be used again.

Recover: In order to make recycling economically feasible, we must recover the recycled products. When we recover the recycled products, we create an economic incentive for recyclable materials to be collected, manufactured, and marketed as new products. Remember, you're not recycling unless you're recovering the recycled products.


The energy sector of Ethiopia is yet to develop in many folds in order to satisfy the socio-economic development needs of the country. The sector constitutes the traditional energy sub-sector which supplies over 90% of the energy requirements and the modern energy subsector that currently provides less than a tenth of the total energy supply but growing at an unprecedented rate, especially regarding the hydropower development.

One area of a considerable energy source is municipal solid and liquid waste, the management of which remains one of the biggest problems for wastes could cause serious health and environmental hazards, and make cities unfit for living. The city of Addis Ababa has a huge problem in this regard although big improvements in waste collection have been observed in recent years.

Noting the energy generation potential of municipal wastes on one hand, and considering the dire need to solve the waste management problems on the other, the promoter of the present project - 4R Energy Pvt. Ltd. Co. (4RE) - has shown interest to engage in the business of converting municipal waste into energy. The wastewater can be turned to energy as well as to organic fertilizers.

Company Profile

4R energy promotes issues that address environmental, socio-economics, energy benefits, waste management and public health benefits, mobilizing stakeholders to facilitating and supporting future bio-energy projects undertaken for alleviating pollution and contributes towards soil conservation and climatic change.

The company is currently completed two separate feasibility studies for biomethane plant complex project that will soon go to realization for production of compressed biomethane gas (CBMG) in gas cylinders in Addis Ababa. The first phase bio-CBMG production project is intended to be used for household uses.

Formation and Capital

4R Energy (4RE) was formed in February 2010 under the laws of Ethiopia. The Company was established by Ethiopian and Ethiopian - American businessmen and entrepreneurs as private limited company. 4RE has principal registration license from the Trade and Industry Bureau of Bole Sub-city of Addis Ababa City Administration.

4RE is currently reforming itself into a share company in order to raise its capital from Birr 10 million to Birr 200 million. This would enable the company to jump start its projects currently at various stages of contract negotiation with two government organs.


4R Energy PLC envisages to be the first leading industrial scale Biogas producing company in Ethiopia and East Africa. It also envisages the company getting involved in various alternative energy sources Such as Wind Energy, Waste to energy, Solar Energy, Biofuel and Thermal Energy.


4R Energy’s ideals and vision emanated from the founder of the company Mr. Benjamin G. Sishuh. The mission of 4R Energy is to produce and market cheaper processed clean compressed biomethane gas (CBMG), organic fertilizers from waste and additional byproducts like liquid transportation fuel to consumers.

The company is planning for the construction of Biogas Plants in different regions of the country. To advance this mission, 4R Energy believes in adopting Government policy’s work jointly with investors and partners, Institutions committed to Strengthening on energy security, improving all aspects of waste management and use, serving as champions of environmental stewardship, and Advancing the health and well-being of the people of Ethiopia.

The mission of 4R Energy is to play a significant role in green house gas (GHG) reduction and poverty alleviation by promoting the production and use of renewable clean sources of fuel, while generating good returns to our investors.

4R Energy PLC ™ has been setup to promote and implement large scale projects based on waste to energy production throughout Ethiopia.


The business objectives of the Company shall be the following:

  • to engage in waste to energy projects,
  • to market and sell compressed and upgraded biogas,
  • to market and sell organic bio-fertilizer,
  • specializing in designing and customizing biogas production including upgrading technologies,
  • improving future bio-energy technologies in R&D, and
  • to provide management and consultancy services on solid and liquid waste treatment projects.

Kaliti Biogas Upgrading Project.

This is based on the biogas generated from the expanded facility of Kaliti Wastewater Treatment Plant, which is owned by Addis Ababa Water and Sewerage Authority (AAWSA). The biogas generated will be purified from carbon dioxide and contaminants by the upgrading plant to be established at the site. The upgraded biogas is then compressed and bottled in high pressure cylinders to be distributed to consumers in Addis Ababa. Currently, 4RE has completed the feasibility study of the project and is presently working on the final stage of the contract to be signed with AAWSA.

Akaki-Chafe Biogas Upgrading Project.

This is similar to the Kaliti plant stated above but with small capacity. The status of the project is also at the same level with that of Kaliti.

Repi Landfill Gas Upgrading Project.

This is based on the landfill gas extracted from the Repi Municipal Solid Waste Dump/Landfill Site, which is owned by Addis Ababa City Administration and managed by Solid Waste Recycling and Disposal Project Office (SWRDPO) under the city administration. Similar to the biogas, the landfill gas recovered will be purified from carbon dioxide and contaminants by the upgrading plant to be established at the site. The upgraded biogas is then compressed and bottled in high pressure cylinders to be distributed to consumers in Addis Ababa. Currently, 4RE has finalized the feasibility study of the project and is perusing discussions with SWRDPO on contractual issues.

As a first strategic step towards achievement of its objectives, 4R ENERGY has set up a Head Office in Addis Ababa in Bole sub-city. From this, work has been done to prepare 4R E’s business plan, including marketing and research into the biogas and energy sectors, study of technologies, identification of strategies and resources.

It is with the objective of exploiting the existing potential of utilizing biogas from various organic municipal solid and liquid wastes in a comprehensive manner for generation and upgraded biomethane production for fuel and other related by-products, such as bio-fertilizers.
