Biodigester Market Report 2026

The biodigester market size has grown strongly in recent years. It will grow from $29.66 billion in 2025 to $31.79 billion in 2026 at a compound annual growth rate (CAGR) of 7.2%. The growth in the historic period can be attributed to increasing agricultural waste generation, adoption of traditional biogas plants, rising energy demand in rural areas, expansion of livestock farming, availability of low-cost organic feedstock.

The biodigester market size is expected to see strong growth in the next few years. It will grow to $41.48 billion in 2030 at a compound annual growth rate (CAGR) of 6.9%. The growth in the forecast period can be attributed to increasing focus on decentralized renewable energy, rising government support for rural biogas programs, expansion of organic fertilizer usage, growing demand for sustainable waste solutions, increasing adoption of climate-resilient energy systems. Major trends in the forecast period include increasing adoption of farm-scale biodigesters, rising demand for modular biodigester units, growing integration of digestate-based fertilizers, expansion of community waste management systems, enhanced focus on low-cost digestion models.

The rise in organic waste generation is expected to drive the growth of the biodigester market in the coming years. Organic waste refers to biodegradable materials, such as food scraps and yard waste, that naturally decompose over time. The increase in organic waste generation is fueled by population growth, higher food consumption, and expanding agricultural and industrial activities. Biodigesters address organic waste management by converting organic materials into biogas and digestate, thereby reducing waste volume, recovering valuable energy, and producing nutrient-rich by-products for soil improvement. For example, in March 2025, the Australian Organics Recycling Association, an Australia-based national organization for resource recovery and organics management, reported that in 2023-24, Australia managed 14.9 million tonnes of organic waste, recycling 51.4% and recovering 61.9% overall, including energy, while 5.7 million tonnes were sent to landfill. Consequently, the increasing generation of organic waste is fueling the growth of the biodigester market.

Leading companies in the biodigester market are focusing on developing innovative products, such as advanced biodigester systems, to improve organic waste management, reduce environmental impact, and promote sustainability across various industries. Biodigester systems are advanced waste management technologies that use natural aerobic digestion to break down food waste into water, significantly reducing the amount of waste sent to landfills. For example, in June 2024, Power Knot, a US-based manufacturer of food waste digester machines, deployed multiple units of its LFC biodigester on the Margaritaville at Sea Islander cruise ship. This cutting-edge system processes between 10 kg (20 lb) and 6000 kg (13,200 lb) of waste per day, offering nine different size options. Installed strategically in galleys and garbage rooms for maximum efficiency, the eco-friendly LFC biodigester reduces the need for traditional disposal methods, cuts operational costs, and supports the ship's sustainability efforts, helping to protect ocean environments for future generations.

In December 2025, Martin Energy Group, a US-based energy solutions company, acquired Chomp for an undisclosed amount. Through this acquisition, Martin Energy Group seeks to expand its food waste-to-energy solutions portfolio and reinforce its position in the renewable energy sector. Chomp Technologies Inc. is a US-based technology company that specializes in delivering innovative food waste management solutions using advanced anaerobic digestion technology.
