Neocrete 籌得 350 萬美元，汶萊低碳混凝土進入港口規模化

紐西蘭低碳混凝土技術商 Neocrete 完成 350 萬美元募資，將擴大歐洲、美國與東南亞業務。公司添加劑讓品質較低的飛灰或火山灰替代部分水泥，汶萊專案已成為首個商業規模案例。

New Zealand low-carbon concrete company Neocrete has raised USD 3.5 million to expand in Europe, the United States and Southeast Asia. Its additive enables lower-quality fly ash or volcanic ash to replace part of cement, with a Brunei project serving as its first commercial-scale case.

Neocrete 於 2018 年由 Zarina Alexander 與 Matt Kennedy-Good 創立。水泥製造約占全球二氧化碳排放的 8%，營建業因此尋求輔助膠結材料，但可用的高品質飛灰與爐石供應有限。

Neocrete was founded in 2018 by Zarina Alexander and Matt Kennedy-Good. Cement production accounts for roughly 8 percent of global carbon dioxide emissions, driving demand for supplementary cementitious materials even as supplies of high-quality fly ash and slag remain constrained.

提高替代率不能犧牲強度、耐久性、施工性與在地法規。飛灰來源和品質差異也會影響配方；避免排放數字若未揭露基準配方、材料運輸、添加劑製造與實際澆置量，容易被高估。

Higher substitution cannot compromise strength, durability, workability or local compliance. Ash origin and quality affect mix design. Avoided-emissions claims can be overstated without a disclosed baseline, material transport, additive production and actual poured volume.

Neocrete 表示其活化添加劑可讓較低品質灰料替代 30% 至 50% 水泥，並提升輔助膠結材料表現。新資金由 Wavemaker Ventures、Icehouse、Temasek Trust 的 C3H 計畫與天使投資人支持，用於跨市場擴張。

Neocrete says its activation additive lets lower-quality ash replace 30 to 50 percent of cement and improves supplementary-material performance. Wavemaker Ventures, Icehouse, Temasek Trust's C3H programme and angel investors backed the round for international expansion.

Readymix Brunei 自 2025 年採用技術，已澆置約 3,700 立方公尺、以灰料替代 30% 水泥。公司案例估計內含碳降低 25%、避免約 215 噸二氧化碳並節省近 2 萬美元。Muara 港的 65,000 立方公尺、5,200 噸避免量與約 30 萬美元節省仍屬預估，不是已交付成果。

Readymix Brunei has used the technology since 2025 and poured about 3,700 cubic metres with 30 percent cement replacement. The company case estimates a 25 percent embodied-carbon cut, around 215 tonnes of carbon dioxide avoided and nearly USD 20,000 saved. Muara Port figures of 65,000 cubic metres, 5,200 tonnes avoided and roughly USD 300,000 saved are forecasts, not delivered outcomes.

若低品質灰料能穩定使用，既有工業副產品可擴大成為在地低碳建材來源，降低水泥用量與成本。長期供應仍須考量燃煤退場後飛灰減少，以及其他礦物原料的品質與可追溯性。

If lower-grade ash can be used consistently, existing industrial by-products could become local low-carbon material and reduce cement cost and volume. Long-term supply must still account for declining fly ash as coal generation retires and for traceable quality in alternative minerals.

SNN 編輯分析：混凝土證據鏈應從灰料來源、配比與批次，連到強度和耐久測試、主管機關驗證、實際澆置量、環境產品宣告、生命週期邊界及完工後績效。已澆置成果與未來預測應分開呈現。

SNN editorial analysis: A concrete evidence chain should connect ash origin, mix and batch to strength and durability tests, regulatory verification, actual poured volume, environmental product declarations, life-cycle boundaries and in-service performance. Delivered results and future forecasts should remain separate.

後續應追蹤 Muara 港實際使用量與完工數據、G25 至 G50 等級的長期耐久性、第三方生命週期查證，以及歐美市場的法規核准與商業採用。

Further evidence should cover actual Muara Port volumes and completion data, long-term durability across G25 to G50 grades, third-party life-cycle verification and regulatory and commercial adoption in Europe and the United States.
