Zhang Guohua, former secretary of the Nantong Municipal Committee of the CPC, during his investigation of straw energy utilization, expressed his hope that Haimen would accumulate experience for Nantong.

Zhang Guohua, former secretary of the Nantong Municipal Committee of the CPC, visited Xingrong Grass Industry Company in Nantong to learn in detail about the processing and operation of straw energy utilization. Xingrong Grass Industry Company is a straw energy utilization processing enterprise in our city, which has achieved a one-stop service for straw acquisition, mechanized baling, stacking, pressing, transportation, and sales. This year, the company invested 1.8 million yuan to improve the company's collection and storage capacity, expanding and renovating 3,000 square meters of processing and storage sites, adding one granulation production line, one granulator, 20 straw balers, 5 transport vehicles, and one large crusher...

Alkalization treatment method for straw

Caustic soda solution treatment. Caustic soda, also known as sodium hydroxide, is used at a rate of 4-5 kg per 100 kg of straw. It is dissolved in 80-100 kg of water and left at room temperature for 8-10 hours before use. Alternatively, a caustic soda solution can be used to spray, moisten, mix, and compact crushed straw into block-shaped feed for long-term use.

Straw densification technology

Straw densification technology uses agricultural waste such as rice straw, wheat straw, and corn stalks as raw materials. Through specialized equipment, a straw baler, and processes such as crushing and compression, it is pressed into a solid biomass fuel that can be directly burned.

Straw ammoniation process

Choose a location for the pond that is higher in elevation, convenient for storage, and easy to manage. The size of the pond can be determined according to needs. The ammonification pond for this project is semi-underground, made of brick and concrete. Urea ammonification agent is used. The urea is prepared into a solution according to requirements and sprayed onto the straw in several batches, mixing evenly. The pond is filled while compacting the material. After filling, it is covered and sealed with a thin film, and then pressed down with a weight.

Regeneration of straw

The Renewable Clean Energy Laboratory of the University of Science and Technology of China announced a new technological achievement developed by Professors Zhu Xifeng, Guo Qingxiang, et al., that can fundamentally solve this long-standing problem. They use pyrolysis liquefaction and reprocessing of various raw materials such as sawdust, rice husks, corn stalks, and cotton stalks to transform waste into treasure, converting them into bio-oil. The oil yield from sawdust is over 60%, and the oil yield from straw is over 50%, with the bio-oil calorific value of 16-18 MJ/kg. This achievement has undergone pilot testing, and industrialization is imminent.
