China launches special scientific research and development to solve the problem of kelp drying
The National Science and Technology Support Program “The deep processing of fresh kelp as raw material and the key technology research and industrialization development of algae chemical industry†project was formally launched in Jinan, Shandong on the 19th.
At present, China’s kelp aquaculture production ranks first in the world, with an annual output of 800,000 tons of light dried kelp, accounting for two-thirds of China’s total seaweed production, and an annual economic benefit of more than RMB 3 billion. At the same time, China’s seaweed chemical industry enjoys a rapid development momentum. China’s alginic acid The annual output of sodium has reached 30,000 tons, ranking first in the world. However, China's kelp industry also has problems such as resource utilization, low product added value, high production costs, poor economic returns, and serious environmental pollution.
This project was one of the key projects initiated by the Ministry of Science and Technology in the local leading national science and technology support program last year. It takes the direct use of fresh seaweed as a starting point, focusing on the research and development of fresh kelp preservation, active ingredient extraction, safe kelp food processing, comprehensive utilization of waste and technological process Wastewater purification and recycling technology will increase the utilization rate of cultured kelp resources and achieve the goal of saving water and reducing emissions from kelp chemicals.
The director of the Department of Science and Technology of Shandong Province, Lu Luning, said that after the promotion of the technology in the country, the annual output will increase by more than 3 billion yuan, saving freshwater resources and reducing sewage discharge by nearly 3 million tons.
