International lead! Straw lignocellulose separation technology breakthrough!

On March 9, the "Straw Lignocellulosic bioenzyme depolymerization three-component separation technology and complete set of equipment" jointly developed by Shenzhen Zhongnong Jome Technology Co., LTD. (hereinafter referred to as "Shenzhen Jome") and Tianjin University of Science and Technology passed authoritative identification and was evaluated as "international leading level".

It is worth noting that the national Tai Suzhi Wine Industry Group has reached a strategic cooperation with Shenzhen Jimei, and will take the lead in applying this technology in the recycling treatment of wine waste.

Technological breakthrough: biological enzyme depolymerization "eating dry pressed" straw resources

China produces nearly 1 billion tons of crop straw every year, and the amount of recoverable resources exceeds 700 million tons. Traditional treatment methods have pain points such as low utilization rate and heavy pollution. The identified technology is based on synthetic biology as the core, and the cellulose, hemicellulose and lignin in the straw are efficiently separated by highly active biological enzymes independently created, and the utilization rate of raw materials is close to 100%. Compared with the traditional process, the technology reduces energy consumption by 70%, saves water by 80%, and there are no chemical additives in the whole process, eliminating black liquor emissions from the source.

The separation and pretreatment of high quality three elements and their conversion into downstream high-value products have always been a key problem in the utilization of lignocellulose.

What are the problems in industrialization and economy of three-element separation?

At present, partial separation of these three components can be achieved by chemical treatment methods such as acid, base and organic solvent, but usually only one or two of them can be used, and it is difficult to realize the high-value utilization of the three elements. Secondly, there are a series of problems such as extraction, separation and purification process consumption, energy consumption, water consumption to sewage. In addition, how to separate the three elements with high quality to obtain the raw materials that are easy to use on a large scale is the key problem for lignin to be used as renewable chemical raw materials.
