Thai researchers develop method to turn fish waste into high-value calcium product

Similar projects to convert waste into valuable products are also being implemented in other countries, including BRICS partners and members.

Scientists at the Shanghai-based East China University of Science and Technology have developed a method for converting food waste into biofuel for ocean-going vessels. The method is based on converting biogas into methanol, reports China Daily, a partner of TV BRICS. Thanks to this technology, organic waste is turned into a useful product, and fuel production costs are reduced by 30 per cent. A pilot plant has been built using patented solutions, including electrically driven biogas reforming (the conversion of methane contained in biogas into hydrogen and carbon monoxide to produce synthesis gas and subsequently methanol). Industry experts believe that this development strengthens the foundation for the global shipping industry’s transition to a green economy.

In Venezuela, scientists are working on a project to process crab production waste into an antimicrobial component. The raw material undergoes initial cleaning, drying and grinding, after which chitin is extracted to produce chitosan, reports Venezolana de Televisión, a partner of TV BRICS. This substance has biodegradable and antimicrobial properties and is used in medicine, agriculture, water treatment and the production of environmentally friendly materials. In agriculture, chitosan acts as an organic plant protection agent; in the food industry, it is used as a clarifying and antimicrobial agent; and in medicine, it helps reduce fat absorption and is used in tissue engineering.

Scientists from India and China have jointly developed a method for turning fallen apple leaves into an eco-friendly agent to protect metals from corrosion. Researchers from Nagaland University and Beijing University of Science and Technology have extracted microscopic particles from the leaves that can provide long-term protection for metal against degradation. During tests, these particles inhibited copper corrosion in a highly acidic environment by 94 per cent at low concentrations and by 96.2 per cent with prolonged exposure, as reported by ANI, a partner of TV BRICS. The development could help solve a global industrial problem by reducing reliance on toxic chemicals. Furthermore, this approach transforms agricultural waste into valuable materials, helps develop a circular economy and can generate additional income for farmers.
