- Tether partners with Adecoagro to mine Bitcoin using surplus renewable energy from biomass and bioenergy in Brazil.
- The project aims to optimize energy use, diversify revenue, and launch open-source Bitcoin mining software.
Brazil is not just famous for its coffee and football. Earlier this July, the country became the stage for a collaboration between USDT issuer Tether and agribusiness giant Adecoagro. The two signed a memorandum of understanding (MoU) to convert surplus renewable energy—mainly electricity from sugarcane waste and bioenergy plants—into Bitcoin mining “fuel.”
The initial target is 230 MW, enough to drive around 6.9 EH/s of hash rate. If that figure is achieved, it will contribute more than 1.5% of global grid power. That’s quite a lot, especially since the electricity is not from coal, but from plantation byproducts.

Green Energy Meets Bitcoin Mining
Adecoagro has been selling excess power to the spot market. However, spot prices often fluctuate, while Bitcoin mining offers a more stable cash flow. On the other hand, Tether has been actively shifting its mining footprint to renewable energy.
Last April, for example, the company transferred its hashrate to the OCEAN protocoltransferred its hashrate to the OCEAN protocol for a more decentralized mining structure. Tether is also preparing its own Mining OS—it says it will make it public—to maximize the efficiency of new rigs in Brazil.
That’s not all, CNF has previously highlighted Tether’s work outside of mining. In Zanzibar, the company has signed another MoU to promote digital asset literacy and the integration of stablecoins into local payment systems. These cross-continental relationships are a pattern: Tether seems to want to be at the crunch point between energy, finance, and digital infrastructure—killing three birds with one stone.
Tether Pushes Boundaries with Local AI and Sustainable Mining
What’s the point of green mining if the technology still relies on traditional, power-hungry clouds? That question was answered in mid-May when Tether launched QVAC, a decentralized AI platform that runs directly on users’ devices. QVAC can process translations, and even make Bitcoin or USDT payments, without having to send data to a central hub.
For Adecoagro, this solution is appealing: they’re not just mining coins, they’re also potentially adopting a standalone, bandwidth-efficient software ecosystem.
However, the Brazilian project is still in the design stage. Adecoagro’s independent committee has given the green light, but a series of technical tests, environmental permits, and adjustments to the local power grid still need to be completed.
There’s also the question of Bitcoin’s volatility: what if the price crashes when the new rigs come online? Executives casually answer, “There’s always market risk, but the energy that was wasted now has a steady buyer.”
After all, biomass power is still generated every milling season; the only other options are to sell it to the grid at a lower price or shut down the turbines.
On the other hand, public sentiment is shifting. Biomass-based mining is seen as more environmentally friendly than giant gas-fired data centers. Many analysts in Brazil see the Tether-Adecoagro model as a blueprint for other agricultural sectors with surplus electricity.
Furthermore, if the project is successful, Adecoagro could potentially add Bitcoin to its balance sheet, alongside its land assets—a kind of digital savings account alongside its farmland.
