COMPANY DESCRIPTION

MASH Makes transforms agricultural residues into sustainable, high-impact products through pyrolysis—a thermochemical process that heats biomass at high temperatures without oxygen. In 2024, the MASH Makes commercial facility in Karnataka, India transformed agricultural waste from the cashew value chain into 1,300 tonnes of biochar and 650 tonnes of biofuel. The company aims to have four sites completed by the end of 2025 and remove 1 megatonne of carbon by 2030.
MASH Makes is on a mission to remove a gigaton of CO₂ in the coming decades through carbon removal technologies. Their next innovation stage includes commercial development of the company’s gasification technology in 2025, which allows for massive scale, diverse feedstocks, and versatile future-ready outputs.

CORE INNOVATION

The MASH Makes’ business model is designed for scalability and maximum environmental impact. This model produces two products:

• Biochar: MASH Makes Biochar is proven to improve soil health, enhance water retention, and boost crop yields for at least four seasons.
• Marine-grade biofuel: A commodity standard, ISCC EU-certified fuel that is comparable with ISO8217 standards. It is designed to work as a drop-in fuel for the shipping industry.

CO2 CAPTURE

MASH Makes processes biomass through pyrolysis, a high-temperature, oxygen-free method that converts carbon into stable biochar and produces engine-grade biofuel as a by-product. Unlike traditional biomass use, pyrolysis locks carbon away in a form that can remain in soils for centuries to millennia, providing a long-term solution to atmospheric carbon capture.

CO2 SEQUESTRATION

MASH Makes sequesters carbon by transforming CO₂ into biochar, which is then applied to soil to create a long-term carbon sink. To maximise its effectiveness, biochar is mixed with nutrient-rich mediums like compost or organic fertilisers before being used as a soil additive. Once in the soil, biochar remains recalcitrant to biodegradation, resisting decomposition and remaining stable for thousands of years.

CO-BENEFITS OR PRODUCTS

MASH Makes’ solutions provide multiple benefits beyond carbon removal, addressing energy, agriculture, and community development challenges.

• Marine-grade biofuel: This sustainable energy source supports the decarbonisation of hard-to-abate sectors like shipping and heavy industries.
• Enhanced agricultural yields: Biochar improves soil health, increases water retention, and boosts crop productivity. Higher yields improve incomes and food security, while generating more biomass. This creates a regenerative, circular system that feeds back into sustainable production and consumption.
• Community and environmental impact: By operating in the Global South and collaborating with marginalised communities and farmers, MASH Makes enhances local economies and supports sustainable land use practices.

MASH Makes also contributes to UN SDGs 2, 8, 9, 11, 12, and 15.
