Kenya's waste management and circularity sector is rapidly emerging as a critical area for sustainable investment. Across the ten sub-sectors and 122 businesses identified within this space in KOIS and ANDE’s Introductory Guide to Investing in the Waste and Circularity Sector in Kenya , four key sub-sectors have demonstrated particularly high potential for investment. Those sub-sectors are organic waste, plastic waste, wastewater, and integrated waste management. This investment guide outlines the complex landscape of the sector, highlighting critical financing needs and investment strategies. While detailed deep-dive guides have been developed to explore each of the four key subsectors, this guide focuses on the financial dynamics that underpin successful investments. It examines the varying financing needs across the different stages of business maturity and sub-sectors. Moreover, it highlights the key factors of success for waste management and circularity businesses, investment trends, gaps and opportunities for innovative finance solutions that could shape the sector. Finally, this guide provides insights into how investors can strategically position themselves and better catalyse investment to grow the sector.

Kenya generates substantial volumes of wastewater from domestic, industrial and agricultural sources — amounting to 800 million litres per day from domestic use alone.2 The country faces significant challenges in managing this wastewater effectively, which increases pressure on limited local freshwater resources. For instance, only 30% of the 400 million litres of wastewater generated daily in Nairobi undergoes treatment, and only 5% of wastewater from offsite sanitation management (OSM) is effectively treated because of failures in the sewage system, a lack of treatment infrastructure and facilities operating below capacity. These problems are exacerbated as transport trucks resort to illegal dumping in nature due to high discharge costs. As wastewater contains contaminants such as chemicals, oils and human waste, this results in heavy pollution of water bodies, endangering aquatic ecosystems and public health. This study employed a mixed-methods approach to conduct a deep dive into the wastewater management sub-sector in Kenya. Our study identified 27 active businesses in this field, including a few growth-stage businesses which have achieved scale through innovation, acquisition of effective technologies, and establishing strategic partnerships, such as the Fresh Life partnership with Regen Organics to convert waste collected by Fresh Life.

Kenya generates 880,000 tons of plastic waste per year, comprising various subcategories such as polyethylene (PE), polypropylene (PP), polystyrene (PS), polyvinyl chloride (PVC), and polyethylene terephthalate (PET), with PET, PP and polyester being the most prevalent. The widespread use of plastic, particularly in urban areas, combined with inefficient waste management systems, leads to the pollution of water resources and severe negative impacts on marine life. Furthermore, plastic waste disposed in nature or in landfills emits greenhouse gases during its decomposition. Out of the 122 businesses identified through this study, 17 businesses operating in the plastic waste management sub-sector in Kenya have been identified, covering applications ranging from plastic waste reduction, recycling into new plastic products and waste conversion into energy. This study employed a mixed-methods approach to conduct a deep dive into the plastic waste management sub-sector in Kenya. Out of the 122 businesses identified through this study, 17 businesses operating in the plastic waste management sub-sector in Kenya have been identified, covering applications ranging from plastic waste reduction, recycling into new plastic products and waste conversion into energy.

Organic waste, which amounts to 5.72 million tons every year in Kenya, spans diverse sub-categories including food waste, yard waste, animal waste, agricultural waste, wood waste, organic sludge, biodegradable waste and human waste (faecal sludge). Rural households typically compost around 75% of their organic waste, but only 25% is composted in urban areas. Although organic waste degrades quickly and does not stay in the environment, it emits methane emissions during degradation or incineration. The high prevalence of open defecation due to inadequate sanitation systems further contributes to these challenges, as only 30% of the population has access to safely managed sanitation services.Effective organic waste management can reduce greenhouse gas (GHG) emissions, deforestation and soil degradation by providing sustainable alternatives to fuel, charcoal, wood and chemical fertilizers. For instance, transforming organic waste into biogas saves about 370–400 kg of carbon dioxide equivalent (CO2e) per ton, while turning it into fertilizers saves 350 kg CO2e per ton.Given the large volumes of recyclable material and its numerous applications, organic waste management is one of the most developed waste management sub-sectors in Kenya. Out of 122 waste management and circularity businesses identified through this study, 30 deal with organic waste, most of which were established over the past decade. This study employed a mixed-methods approach to conduct a deep dive into the organic waste management sub-sector in Kenya. 

Every day, Kenya produces over 24,000 tons of waste, amounting to 8.8 million tons annually. Most of this waste is currently mismanaged, with more than 75% of waste in Kenya being incinerated or disposed at dumpsites. Moreover, Kenya is home to two of the world's 50 largest landfills – Dandora in Nairobi and Kibarani in Mombasa – highlighting its significant waste management challenges. Mismanaged waste in Kenya poses several environmental and health risks, which local actors are yet to comprehensively address. The proximity of landfills to residential areas in Kenya negatively impacts the quality of life of nearby communities and poses severe health risks by contaminating local land and water resources. In addition, waste incineration releases toxic pollutants into the air, water and soil and produces hazardous ash that can contaminate the environment and pose health risks to nearby communities. This study identified 16 small and growing businesses (SGBs) providing integrated waste management services.
