Abstract

Sugarcane (Saccharum officinarum) is Louisiana's number one row crop. Growing and processing sugarcane produces significant amounts of byproducts, including bagasse, crop residue, molasses, filter-press mud, and boiler fly ash. These products represent an important opportunity to generate value-added and specialty products and enhance sugarcane's sustainability by facilitating a circular economy, where agricultural by-products are reused instead of disposing them (linear economy), in order to reduce resource use and energy demand. Examples of value-added products range from biochar, construction materials, animal feed, biofuels, nanoparticles, and fertilizer. Paramount to the success of the bio-based circular economy is creating useful products that are sustainable, economically, and environmentally acceptable. Some potential roadblocks to creating a successful bio-based circular economy from Louisiana's sugarcane by-products are highlighted.

Core Ideas

  • The Louisiana sugar industry produces large amounts of biomass-derived byproducts each year.
  • Byproducts could be reused, recycled, or reformed instead of being discarded.
  • Creating industries around these products boosts the circular economy.

利用路易斯安那州甘蔗副产品创建以生物为基础的循环经济
甘蔗(Saccharum officinarum)是路易斯安那州的第一大农作物。甘蔗的种植和加工会产生大量的副产品,包括甘蔗渣、作物残渣、糖蜜、压滤机泥浆和锅炉粉煤灰。这些产品是生产增值产品和特色产品的重要机会,也是通过促进循环经济(即农业副产品的再利用而非处置(线性经济))来减少资源使用和能源需求,从而提高甘蔗可持续发展能力的重要机会。增值产品包括生物炭、建筑材料、动物饲料、生物燃料、纳米颗粒和肥料等。以生物为基础的循环经济要取得成功,最重要的是创造出在可持续发展、经济和环境方面均可接受的有用产品。本文重点介绍了利用路易斯安那州甘蔗副产品成功创建生物基循环经济的一些潜在障碍。 核心观点 路易斯安那州制糖业每年生产大量生物质副产品。 副产品可以重新利用、回收或改造,而不是丢弃。 围绕这些产品创建产业可促进循环经济。
