Israeli climate‑tech firm CarbonBlue unveiled its EcoLime process, a renewable‑energy‑driven method that could slash emissions from lime production, during a PLANETech Week visit to its Kibbutz Maagan Michael site.

The delegation, representing the PLANETech Investor Alliance – the region’s leading climate‑tech investor group – toured CarbonBlue alongside startups HomeBiogas, H2PRO and Brenmiller Energy Tempo, each presenting performance updates.

CarbonBlue’s EcoLime combines solar‑powered electro‑lysis with its AquaFix technology, which extracts CO₂ from desalination water, allowing lime to be produced while simultaneously capturing greenhouse gases.

“Our EcoLime process cuts the carbon intensity of lime by up to eighty percent,” said Adam Etzion, Marketing and Communications Manager, adding that the pilot at Kibbutz Maagan Michael’s desalination plant is already delivering measurable reductions.

Dr. Noga Friedman Bishop, Vice‑President of R&D, explained that integrating AquaFix into existing water‑treatment facilities enables industries to lower energy use and improve water quality, creating co‑benefits across the value chain.

Iddo Tsar, CarbonBlue’s COO and founder, highlighted the company’s floating solar array on a nearby fish pond, which powers the pilot and demonstrates that climate mitigation can coexist with productive agriculture.

Lime production accounts for roughly eight percent of global CO₂ emissions, a figure that resonates in Ghana where the construction sector relies heavily on locally produced lime for mortar and plaster.

“If such technology can be adapted to Ghanaian factories, it could reduce emissions while keeping costs competitive for building projects,” commented Kwame Agyeman, a senior analyst at the Ghana Investment Promotion Centre, who was briefed on the visit.

The Israeli government, through the Israel Innovation Institute and the Consensus Business Group, backs PLANETech as a platform to showcase solutions that could be exported to Africa and the Global South.

CarbonBlue hopes to pilot its EcoLime system in Ghana within the next two years, inviting local partners to explore joint ventures that align with Ghana’s Renewable Energy Act and climate‑change commitments.

The rollout of EcoLime could mark a pivotal step toward decarbonising a traditionally hard‑to‑abate industry, offering Ghana and other emerging economies a blueprint for greener construction materials.
