“第二座矿山”是一个比喻性概念，意指“第二次挖掘”或“第二次生产”，强调在既有地方系统中探索新资源、新潜力与新机会，以应对在地环境危机，推动向可持续资源利用方式的转变。

“The Second Mine” is a metaphorical concept, signifying “second excavation” or “second production.” It emphasizes the exploration of new resources, new potential, and new opportunities within existing local systems, in response to local environmental crises and the urgent need to transition toward sustainable resource utilization.

城市矿产
Urban Mining

在鄱阳湖与长江交汇处的湖口县，神华电厂每天产生大量粉煤灰。粉煤灰是指燃煤电厂及煤矸石、煤泥等资源综合利用过程中，锅炉烟气经除尘器收集后得到的细小飞灰与炉渣。据统计，每燃烧100吨煤炭，平均生成15至45吨粉煤灰。长期以来，粉煤灰主要以填埋和堆放方式处理，不仅占用大量土地，还对水质、土壤和空气造成影响，构成生态与社会风险。但从循环利用的视角看，粉煤灰又堪称名副其实的“城市矿产”。

At Hukou County, where the Poyang Lake meets the Yangtze River, the Shenhua Power Plant generates a large amount of coal fly ash daily. Fly ash refers to the fine ash and furnace slag collected by dust collectors from boiler flue gases during the comprehensive utilization of coal-fired power plants, coal gangue, and coal slime. According to statistics, for every 100 tons of coal burned, an average of 15 to 45 tons of fly ash is produced. For a long time, fly ash has been primarily disposed of through landfilling and stockpiling, which not only occupies vast amounts of land but also impacts water quality, soil, and air, posing ecological and social risks. However, from the perspective of circular utilization, fly ash truly deserves the title of “urban mining.”

上一个产业的废弃物成为下一个产业的原材料

Waste from One Industry Becomes Raw Material for Another

“X”是一件户外混凝土家具，由“本土创造”利用神华电厂的粉煤灰进行材料研发与产品打造。它以“上一个产业的废弃物成为下一个产业的原材料”为理念，是一次本地化生产的可持续设计实践。

“X” is a piece of outdoor concrete furniture developed by “BENTU DESIGN” using fly ash from the Shenhua Power Plant for material research and product creation. Guided by the philosophy that “waste from one industry becomes the raw material for another,” it represents a sustainable design practice rooted in local production.

在混凝土中，水泥是碳排放最高、成本占比较大的部分。合理利用粉煤灰，可在维持胶凝材料总量不变的前提下降低水泥熟料用量，其作用已超越传统混凝土中“节约水泥”的范畴。通过科学配比，粉煤灰的掺入能够优化材料的微观结构，提升制品的抗渗性、抗裂性与长期稳定性。在“X”户外家具中，粉煤灰不仅作为惰性填充料，更凭借其微集料效应与后期火山灰活性，成为实现超高力学性能和优异耐久性的关键。它与矿粉等固废材料形成多元复合体系，使产品固废利用率超过90%。

In concrete, cement is the component with the highest carbon emissions and a significant portion of the cost. The rational use of fly ash can reduce the amount of cement clinker while maintaining the total volume of cementitious materials. Its role has surpassed that of simply “saving cement” in traditional concrete. Through scientific proportioning, the incorporation of fly ash optimizes the material’s microstructure, enhancing the product’s impermeability, crack resistance, and long-term stability. In the “X” outdoor furniture, fly ash not only serves as an inert filler but, leveraging its micro-aggregate effect and later-stage pozzolanic activity, becomes key to achieving ultra-high mechanical performance and exceptional durability. Together with other solid waste materials like slag, it forms a multi-component composite system, enabling the product’s solid waste utilization rate to exceed 90%.

利用产业固废进行可持续设计实践，是在新的话语中重新诠释物质的力量。通过对材料的重新建构，目标在于最大限度将废物转化为可再生资源，减少污染物排放，同时赋予产品以地域性、自然性与多样性的美学特征和情感记忆，探索可持续发展的新解决方案、新文化表达与新商业机会。这种物质循环的理念，正是“第二座矿山”的真实内涵。

Sustainable design practice utilizing industrial solid waste reinterprets the power of materials within a new discourse. Through the reconstitution of materials, its goal is to maximize the transformation of waste into renewable resources, reduce pollutant emissions, while endowing products with regional, natural, and diverse aesthetic qualities and emotional resonance. It seeks to discover new solutions, new cultural expressions, and new business opportunities for sustainable development. This concept of material circulation is precisely the true essence of “The Second Mine.”
