Tether, the company behind the world’s largest stablecoin, is preparing to mine Bitcoin using electricity generated from sugarcane waste in Brazil, and the pilot is set to go live by July 1, 2026. The operation, run through Tether-backed agribusiness Adecoagro, will start with 10 megawatts of capacity and approximately 1,280 Bitcoin mining machines powered entirely by biomass energy from sugarcane processing.
Adecoagro already operates more than 230 megawatts of renewable electricity generation capacity across South America, giving the project an established energy platform before a single mining rig is switched on.
The 10-megawatt pilot is a small slice of that, deliberately so. This is a test, not a full rollout.
Here is the central tension this article unpacks: sugarcane biomass genuinely offers a cleaner energy source for Bitcoin mining than fossil-fuel grids, and understanding the difference between a circular agricultural economy and a greenwashing narrative matters for anyone trying to evaluate whether this is genuine sustainable infrastructure or a clever piece of brand positioning.

How Sugarcane Biomass and Bitcoin Mining Actually Work Together
Imagine you run a juice factory. Every orange you squeeze leaves behind pulp, a byproduct you didn’t set out to make but now have to deal with. You could throw it away, or you could find someone who wants it. Now imagine that pulp could be burned to generate electricity, and that electricity could run a business 24 hours a day, seven days a week, without any downtime.
That is roughly how bagasse-powered Bitcoin mining works in this context.
Bagasse is the fibrous material left behind after sugarcane is crushed to extract juice for sugar and ethanol production. In large-scale mills, bagasse is fed into high-efficiency boilers that generate steam, which spins turbines to produce electricity.
The process often generates more power than the mill itself consumes, creating surplus electricity that can be sold to the grid or redirected to other uses.

Bitcoin mining steps in as that other use. Mining requires constant, uninterrupted power, making it an ideal flexible buyer for surplus energy that might otherwise be curtailed or sold at low spot prices. In Brazil, where Adecoagro operates across massive sugarcane-growing regions, that surplus is predictable, scalable, and structurally embedded in the existing industrial process.
The key mechanism here is co-generation: one agricultural process produces two sellable outputs, commodity products and electricity. Bitcoin mining adds a third revenue stream without requiring entirely new power infrastructure. That is not a small efficiency gain.

Tether Adecoagro Investment: What the Deal Actually Involves
Adecoagro is a NYSE-listed agro-industrial company with operations across Brazil, Argentina, and Uruguay, spanning sugar, ethanol, rice, dairy, and renewable energy. It owns approximately 210,400 hectares of farmland and produces over 3.1 million tons of agricultural products and more than 1 million MWh of renewable electricity annually.
Tether acquired a majority stake in Adecoagro, giving the stablecoin issuer direct exposure to physical commodities, agricultural land, and renewable energy infrastructure. Adecoagro’s independent committee reviewed and approved the Bitcoin mining pilot under the company’s related-party transaction rules, a procedural detail worth noting because Tether’s ownership position makes governance scrutiny important.

The mining operation will use Tether’s proprietary Mining OS for site management, and the company has indicated the software will be open-sourced following the July 2025 announcement of the partnership.
For Tether, the deal extends a strategy CEO Paolo Ardoino has been vocal about: building toward becoming the largest Bitcoin miner in the world, backed by a reported $2 billion already deployed in energy production and mining operations. Adecoagro gives Tether a renewable energy anchor in one of the world’s most productive agricultural economies.
