メキシコ・トリオン油田の掘削屑を原料にした環境レンガ製造をISO 14040/14044のLCAで評価。太陽熱乾燥によるゼロ排出プロセスを採用し、機能単位1トン当たりの炭素フットプリントは7.17〜8.17 kg CO₂-eqと算出。海上輸送の最適化が環境妥当性を左右する鍵だと示した。
English
A cradle-to-gate LCA (ISO 14040/14044) assesses eco-bricks made from drill cuttings recovered from Mexico's Trion field. Using zero-emission solar drying, the carbon footprint is 7.17–8.17 kg CO₂-eq per ton of masonry. Maritime transport optimization emerges as the decisive factor for environmental viability of this circular-economy route.

📄 Abstract（原文）
Deepwater hydrocarbon exploration generates significant volumes of drilling cuttings, which traditionally represent a heavy logistical burden and a severe environmental risk regarding final disposal. However, their specific mineralogical composition and physical properties enable their effective integration as secondary raw materials in the manufacturing of ecological bricks and blocks for the construction sector. This research evaluates the environmental sustainability of producing alternative construction materials derived from drill cuttings recovered directly from the Trion field in the Gulf of Mexico. Following the standardized guidelines of ISO 14040 and ISO 14044, a comprehensive Life Cycle Assessment was conducted under a cradle to gate approach based on a functional unit of one metric ton of finished masonry. Unlike traditional ceramic processes that rely on high temperature thermal firing, this proposal incorporates a zero emission solar drying technique. Two distinct logistical supply routes to the state of Tamaulipas were thoroughly analyzed: the Port of Matamoros and the Altamira Industrial Corridor. The results reveal that the total carbon footprint ranges between 7.17 and 8.17 kg CO₂-eq per ton. These findings highlight that maritime transportation optimization is the critical determining factor ensuring the environmental viability of this circular economy initiative, successfully minimizing both greenhouse gas emissions and local quarry extraction pressures.
