Potential Investment Opportunities In Agricultural Waste Management Technology

by Sanusi Afeez Opeyemi

There’s an immense opportunity locked in the agricultural sector, and I’m not talking about the crops, meat, milk or eggs. I’m talking about the cow dung, poultry waste, the hays and straws we throw away or burn to clear off the land.

For decades, agricultural waste has been viewed as a burden – an inevitable byproduct of farming that requires costly disposal or treatment. However, a shift in perspective is revealing the immense economic potential locked within these organic residues. Leading investors and entrepreneurs are taking notice, recognizing agricultural waste as a valuable resource ripe for innovative solutions and lucrative opportunities.

In this article, we’ll explore the potential investment opportunities in agricultural waste management technology.

Investment Opportunities in Agricultural Waste Management Technology

The sheer scale of agricultural waste generation is staggering. Annually, crop residues, manure, and other organic wastes from farms and processing facilities amount to 998 million tons. Rather than letting this biomass go to waste, cutting-edge technologies are transforming it into revenue streams and eco-friendly products. 

Here are some examples:

Anaerobic digestion: Anaerobic digestion is a widely adopted technology that converts organic agricultural waste, such as manure, crop residues, and food waste, into biogas (a mixture of methane and carbon dioxide).

The biogas can be used to generate heat, electricity, or upgraded to biomethane for use as a renewable natural gas substitute. This technology is gaining traction globally due to its ability to generate renewable energy, reduce greenhouse gas emissions, and produce nutrient-rich digestate for use as fertilizer.

Composting: Composting is a well-established technology that involves the aerobic decomposition and recycling of organic waste materials, such as crop residues, manure, and food waste, into a nutrient-rich soil amendment or organic fertilizer.

Advanced composting technologies, like in-vessel composting and aerated static pile systems, are gaining attention due to their ability to provide better process control, faster decomposition, and reduced emissions.

Waste-to-energy solutions: Technologies that convert agricultural waste into energy sources, such as electricity, heat, or biofuels, are receiving increasing attention globally. These include biomass power plants that burn agricultural residues to generate electricity, gasification systems that convert waste into syngas for energy production, and pyrolysis technologies that produce bio-oils and biochar from agricultural waste.

Hydrothermal processing: Technologies like hydrothermal carbonization and hydrothermal liquefaction are being explored for converting wet agricultural waste streams into solid biofuels (hydrochar) or liquid biofuels (biocrude), respectively. These processes offer an alternative to traditional thermochemical conversion methods for specific waste streams.

Insect farming: The use of insects, such as black soldier flies and mealworms, to convert agricultural waste into high-protein insect biomass for animal feed or other applications is an emerging technology receiving interest globally. This technology offers a sustainable solution for waste management while producing a valuable protein source.

Top 4 Companies Leading The Agricultural Waste Management Technology Industry

1. Enerkem (Canada): Enerkem is a pioneering company in the development of advanced biorefineries that convert non-recyclable waste, including agricultural residues, into renewable fuels and chemicals. In 2022, the company secured $225 million in funding from investors like Suncor Energy, Repsol, Proman, and Nordea Bank to support the construction of its first commercial-scale biorefinery in Rotterdam, Netherlands.

This facility, expected to be operational by 2025, will have the capacity to process 500,000 tons of waste annually, producing 220,000 tons of biofuels and biochemicals. Enerkem has already successfully operated a demonstration plant in Edmonton, Canada, and has strategic partnerships with major companies like Shell and Sinobioway Group.

2. Verbio (Germany):Verbio tackles the challenge of agricultural waste by transforming it into valuable resources. Through investment in renewable energy, they specialize in a technology called anaerobic digestion, which breaks down organic materials like corn stover in an oxygen-free environment. This process yields biogas, a versatile fuel source. Biogas can be further refined into renewable natural gas (RNG), a clean-burning alternative to fossil fuels.

Verbio’s approach offers a win-win situation. Farmers gain a sustainable solution for disposing of crop residue, a task that can be both time-consuming and costly. Additionally, Verbio’s technology contributes to the production of renewable energy, reducing our reliance on traditional sources.

3. Arensis (United States): Arensis is a waste-to-energy company that develops and operates advanced gasification facilities that convert agricultural residues and other biomass into renewable syngas and biofuels. In 2021, the company raised $14.6 million in funding led by Hadrian’s Wall Secured Investment Ltd. to support the construction of its first commercial-scale facility in Gilroy, California.

This facility, expected to be operational by 2024, will have the capacity to process 285,000 tons of agricultural waste and woody biomass annually, producing over 30 million gallons of renewable biofuels and biochar. Arensis has developed a proprietary gasification technology that can handle a wide range of feedstocks and produce syngas for downstream fuel and chemical production.

4. AgriProtein (South Africa): AgriProtein is a pioneering company in the field of insect farming, using black soldier fly larvae to convert agricultural waste and other organic residues into high-quality protein for animal feed and organic fertilizers. In 2018, the company secured $105 million in funding from investors like Kaumera Nerds Fund and Ubben Innovative Agritech to support the expansion of its global operations.

AgriProtein has successfully operated commercial-scale insect farming facilities in South Africa, processing over 100,000 tons of waste annually. The company plans to use the funding to establish new facilities in multiple countries, including the United States, Asia, and Europe, to meet the growing demand for sustainable protein sources and waste management solutions.
