生物基产品的重要性日益增加，加上减少废物产生的愿望，增加了使用废物作为生物基产品原材料的必要性。废甜菜是一种潜力巨大的废料，主要用作动物饲料或肥料。水热处理后，生成的炭的H/C比为1.2，热值高达22.7 MJ/kg，与次烟煤相似，高于褐煤。此外，通过加热至160℃处理25g/L葡萄糖和22g/L果糖，使得废甜菜可以用于生产5-羟甲基糠醛。在本研究中，加热至200℃后5-羟甲基糠醛的最大浓度为3.4 g/L。
The growing importance of bio-based products, combined with the desire to decrease the production of wastes, boosts the necessity to use wastes as raw materials for bio-based products. A waste material with a large potential is spent sugar beets, which are mainly used as animal feeds or fertilizers. After hydrothermal treatment, the produced chars exhibited an H/C ratio of 1.2 and a higher heating value of 22.7 MJ/kg, which were similar to that of subbituminous coal and higher than that of lignite. Moreover, the treatment of 25 g/L of glucose and 22 g/L of fructose by heating up to 160 °C led to a possible application of spent sugar beets for the production of 5-hydroxymethylfurfural. In the present study, the maximum concentration of 5-hydroxymethylfurfural was 3.4 g/L after heating up to 200 °C.
