The era of circular economy is coming, and waste can also be turned into new business opportunities for the industry!
Plastic turns into gold
Industrial Technology Research Institute, Sun Yat-sen Institute of Science, and Precision Machinery Research and Development Center, three major R&D legal entities, today joined hands at the "Decrypted Technology Treasures Exhibition" at the P2 warehouse in Kaohsiung Pier 2 Art Zone to present "The Alchemy of Resource Recycling" ", demonstrating the application of new technologies developed by the Ministry of Economic Affairs' science and technology project, turning industrial wastewater, empty bottles and cans, and old batteries into new business opportunities, creating more added value, and leading the "green gold new economy."
Industrial Research Institute published "Protein Substrate Gold Recovery Technology" and found that special thermophilic microbial proteins can extract gold from industrial wastewater. When the ITRI R&D team was conducting geothermal research, they originally wanted to use microorganisms in geothermal water to solve the calcium carbonate scaling problem that is easily encountered in geothermal wells. However, they accidentally discovered microbial proteins in geothermal water. , has the function of adsorbing gold, indium and other metal ions.
After three years of hard work, the ITRI team has developed the "Protein Substrate Gold Recovery Technology". Even from low-concentration industrial wastewater, there is a way to extract valuable metals in wastewater. This technology can help gold plating factories, printed circuit boards factories and semiconductor packaging and other industries to recover valuable metals in process wastewater.
The protein material after gold recovery can be made into gold-containing nanoparticles, which are sold as raw materials and can be used as high-value back-end products such as cosmetic bacteriostatic agents or industrial catalysts. Even the "protein substrate gold recycling technology" can be used in the geothermal power generation industry. Recycling valuable or rare metals in geothermal water is a way to make metal resources more effectively used.
In the "Smart Resource Recycling Machine" published by the ITRI Electronic News
Precision Machinery Center, when people put in three Taiwan-made plastic bottles or iron and aluminum cans, the smart resource recycling machine will give back one yuan to the people's one-stop card, which can be used to Taking the MRT or paying a small amount will also help promote the habit of taking the mass rapid transit and light rail transportation systems. Environmental protection combined with low-carbon transportation will kill two birds with one stone. In addition, the precision machine center combines the application of the Internet of Things to automatically notify the cleaning team to pick up the bottles and cans on site when the recycling machine is full.
According to statistics from the Environmental Protection Agency, Taiwan uses at least 4.5 billion plastic bottles (about 100,000 tons) every year, which can stack 3 101 buildings and circle Taiwan 223 times. Based on the recycling concept of recycling, reduction, and reuse, the Precision Machinery Center has currently installed more than 50 recycling machines in FamilyMart convenience stores, mass merchandisers, schools, etc., and has recycled more than 3.02 million pieces so far.
The Chinese Academy of Sciences published the "recycling technology of lithium iron batteries after retirement". It looks like a suitcase for traveling abroad, but it is the secret weapon for the second life of recycled batteries. The Chinese Academy of Sciences pointed out that if the rechargeable capacity of vehicle power batteries is reduced to 80% of the original value, they are ready to be replaced with new ones. However, although these "80% new batteries" are "not powerful enough" for vehicle use, they are not effective for other uses. More than enough.
Chinese Academy of Sciences uses retired lithium iron batteries as the energy storage core. Its appearance is similar to an ordinary luggage compartment and can be easily towed. The outer shell is connected to a universal interface mobile power supply and can be used to replace traditional diesel generators. The design voltage is 12 volts. When needed, the voltage can be increased through series connection. It can fully charge 300 mobile phones and light up a 20-watt light bulb for 90 hours without generator noise. More importantly, it is safe and hassle-free to use. Yu. This product has obtained patent rights and is expected to be mass-produced next year.
