Agricultural independence - oyster shell heating pack can also be used as fertilizer after use

Approximately 100,000 tons of oyster shells are discarded in Taiwan every year. The Water Research Institute of the Ministry of Agriculture turns waste into gold and develops oyster shell self-heat source pack manufacturing technology to replace imported consumables such as aluminum powder and quicklime in the past. It can be heated to more than 80 degrees in a short time. In addition to currently popular heat-and-eat products, it can also be used for war preparedness and disaster prevention food.

In the past, heating pack consumables mostly used aluminum powder and quicklime. The materials cannot be recycled, and almost all of them are imported from China. In order to improve the resilience of my country's industry, Gao Yifeng, an associate researcher at the Water Research Institute, used oyster shells as raw materials to replace aluminum powder and lime powder with oyster shell powder. Just add 150% water. ml, the temperature can rise to over 80 degrees Celsius in five minutes. The heating effect is equivalent to that of commercially available heating packs. Zhang Jinyi, director of the Water Testing Institute, further pointed out that in the past, these heating source materials could only be discarded. In the future, the heated oyster shell powder can be used as fertilizer, which is quite environmentally friendly.

The patent has been transferred to Gulai Biotechnology Company. Wu Zonglin, general manager of the company, said that he had bid for the Ministry of National Defense’s field package bid in the past and found that most of the heating package materials came from China. The technology developed by the water test can completely achieve domestic self-sufficiency. He is also optimistic about business opportunities and has received about two million package inquiry orders, creating an output value of about 100 million yuan.

The team of Cai Huijun, leader of the aquatic products processing group of the Water Testing Institute, has also developed aquatic product conditioning package processing technology. She said that in the past, room temperature ready-to-eat packages were mainly livestock products. Because room temperature products need to be sterilized by high pressure, the fish fiber will be broken in the process. This technology can maintain the meat quality. It is fresh and tender, and the technology has been transferred to Hanshen International, a seabass farming and export agricultural enterprise. Next year, it will launch a normal-temperature aquatic product preparation package such as Shuzi Steamed Seabass, coupled with oyster shell self-heating source package technology, you can eat hot seabass dishes even in the wild or in natural disasters.
