Waste not, watt not – Ontario is proposing changes to the Environmental Protection Act and its Renewable Energy Approvals regulation to recognise the biogenic portion of municipal solid waste as a renewable energy source and allow certain Energy from Waste facilities to use a single Renewable Energy Approval process. The Ministry of the Environment, Conservation and Parks said residual municipal waste used by such facilities is estimated to contain 45-55% biogenic content, including wood, food waste, fabric, and soiled paper, but Ontario currently provides limited recognition of that portion compared with other Canadian jurisdictions. The proposal would update the definition of biomass and create a new thermal treatment class for facilities that incinerate municipal waste containing biogenic content, which the province said could support investment in Energy from Waste, reduce landfill volumes, and increase energy recovery from waste. Feedback on the proposal, posted under ERO number 026-0595, is open until July 20, 2026.

Coffee (CO)2 go – COFCO International, an overseas agribusiness platform of China’s COFCO Corporation, has signed an MoU with a fund managed by Patria Investments, a Latin America-focused global alternative asset manager, to explore sustainable agricultural supply chains and carbon removal credits in Brazil. The agreement includes assessing opportunities tied to coffee, other agricultural commodities, low-carbon logistics infrastructure, and Patria’s Reforest Fund, which focuses on natural capital projects combining ecological restoration with productive land use. The companies said the work could support climate-resilient and regenerative farming practices, restoration of degraded and underutilised land, farmer engagement, capacity building, sustainable livelihoods, and the evaluation of carbon credit generation aligned with recognised standards.

Data demand – US data centres could consume 649 TWh of electricity by 2030 under a reference case, equal to 11.8% of total US electricity use, with scenario results ranging from 521-843 TWh, or 9.5-15.3%, according to a new Lawrence Berkeley National Laboratory update. The report estimated US data centre electricity use at 192 TWh in 2024, or 4.7% of national consumption, and said growth is being driven mainly by the deployment of GPU- and ASIC-accelerated servers for AI workloads. Under the reference case, AI servers would account for 84% of total server energy use and 55% of total data centre energy use by 2030, while projected electricity demand would translate to 148 GW of interconnection capacity, assuming a 50% average utilisation rate.

Biofuel blueprint – North Carolina-based Honeywell will provide modular process technology and automation controls for Acelen Renewables' planned biofuels refinery in Bahia, Brazil, the company announced on Wednesday. Acelen said the project would support the production of lower-emission fuels while promoting biodiversity and sustainable economic development in the region. The Bahia facility is expected to be among the world's largest biofuel refineries once operational, according to the companies. Honeywell added that their Ecofining process efficiently converts waste fats, oils, and greases into renewable diesel and SAF that can reduce GHG emissions by up to 80% when blended with conventional jet fuel.
