Olive mill solid waste (OMSW) is an abundant agricultural waste without viable solution. The effects of OMSW different pretreatments (microwave or autoclave), different additives (water, formic, or sulfuric acid), and utilization of different saccharification enzymes (Cellic® CTec2 or Accellerase® 1500) were tested on saccharification process and sugar release, and on fermentation inhibitors formation and ethanol production. Microwave treatment with formic acid resulted in highest saccharification rates (90% of cellulose fraction) and fermentation yields (15.9 g/L ethanol), although loss of sugars and fermentation inhibitors production was notable. Microwave with water treatment resulted in less saccharification and ethanol (9.6 g/L). To facilitate economical process and to extract maximum value, solid remnants after saccharification were tested as heavy metal sorbent. Microwave with water resulted in the best sorbent, followed by microwave with formic acid. Addition of sulfuric acid, to either microwave or autoclave, resulted in very poor saccharification and absorbance capacity. Therefore, combination of ethanol and sorbent production from OMSW are suggested.

橄榄磨坊固体废物（OMSW）是一种丰富的农业废物，没有可行的解决方案。测试了OMSW的不同预处理（微波或高压灭菌器），不同的添加剂（水，甲酸或硫酸）以及不同糖化酶（Cellic®CTec2或Accellerase®1500）的利用对糖化过程和糖分释放的影响。发酵抑制剂的形成和乙醇的产生。尽管明显损失了糖分和发酵抑制剂的产量，但用甲酸进行微波处理可实现最高的糖化率（占纤维素组分的90％）和发酵产量（15.9 g / L乙醇）。用水处理的微波导致较少的糖化和乙醇（9.6 g / L）。为了促进经济过程并获取最大价值，糖化后的固体残留物用作重金属吸附剂。加水的微波产生最佳的吸附剂，然后加甲酸的微波。向微波或高压釜中添加硫酸导致非常差的糖化和吸收能力。因此，建议结合乙醇和OMSW生产吸附剂。
