NTU researchers develop new way to recycle plastic that leaves minimal carbon footprint
Research Breakthrough: Scientists from Nanyang Technological University (NTU) have developed an innovative method for recycling plastic with minimal carbon footprint
Process Overview: The process employs light and a readily available photocatalyst to efficiently break down plastic materials, including plastic bags, takeaway boxes, styrofoam, and PVC pipes. The resulting acids, like formic acid, acetic acid, and benzoic acid, can be used to produce green fuels, such as hydrogen.
Upcycling vs. Recycling: The researchers prefer the term “upcycling” for this process, as it differs from traditional mechanical recycling that tends to reduce plastic durability.
Commercial Potential: The technology is currently in the process of being patented, and the research team is seeking industry collaborators for commercialization. It offers potential benefits for the clean energy sector, particularly in the development of liquid organic hydrogen carriers (LOHCs) for safer hydrogen transport.
Challenges: Currently, the derived chemicals from this method may be more expensive compared to those produced from fossil fuels. Crude Oil Prices
However, the technology shows potential for producing higher-value specialty chemicals for fragrances and paints.
Efficiency Enhancement: Ongoing research and development aim to improve the efficiency of this technology so that it can process large quantities of plastic waste within a shorter timeframe.
Carbon Footprint: While the exact carbon footprint reduction has not been quantified, the new method is expected to have significantly lower emissions compared to conventional pyrolysis and mechanical recycling processes. Crude Oil Prices
Carbon Storage in Plastics: Plastic waste is highlighted as a form of carbon storage, as it prevents the release of carbon dioxide into the atmosphere. Biodegradable plastics may not necessarily have a smaller carbon footprint due to their chemical makeup.
Environmental Impact: The accumulation of non-biodegradable plastic waste in landfills and the environment has potentially prevented the release of a substantial amount of carbon dioxide, contributing to efforts to limit global warming.
This innovative plastic recycling process has the potential to reduce carbon emissions, enhance the sustainability of plastic materials, and contribute to cleaner energy production. Crude Oil Prices
‘Waste to resources’: SK gets ball rolling in high-tech plastic recycling
The process of recycling plastics is most widely known to be about breaking used plastics into little pieces, washing, sorting and drying them before turning what’s left of them into new plastics.
Chemical recycling, the more sophisticated method, involves extracting raw materials from used plastics or significantly changing the chemical structure of the waste; hence, there is no need to sort by color or condition of contamination.
Korea’s SK Group, the second-largest conglomerate in the country by assets, which has major oil refinery and petrochemical units under its wing, is at the vanguard of chemical recycling as it steps up the drive for a green energy transition toward decarbonization.
In its main refinery and chemical plant in Ulsan, an industrial city on the southeast coast, SK is building what will be the world’s first plastic recycling cluster with core chemical recycling facilities. Crude Oil Prices
The Advanced Recycling Cluster (ARC) will be built on 215,000 square meters of land ― a size equivalent to 22 football stadiums ― inside the 8.3-million-square-meter Ulsan CLX.
The 1.8 trillion-won ($1.35 billion) project is scheduled to break ground next month, aiming to begin operations in 2025.
“Some 320,000 tons of plastic waste ― which is 213 million 500-milliliter PET bottles of water ― will be recycled every year once the ARC is operational,” said Kim Ki-hyeon, an official at SK Geocentric, the chemical unit in charge of the ARC, during a press tour in Ulsan on Wednesday.
The recycling cluster will house three major chemical recycling facilities: high-purity polypropylene (PP) extraction, depolymerization of PET plastics or polyester, and pyrolysis.
Depolymerization chemically turns plastic and fiber waste into the original form of monomers and enables recycling without quality degradation. SK is working with Canada’s Loop Industries on the depolymerization technology.
For PP extraction, SK is collaborating with U.S. Purecycle Technologies, which specializes in extracting ultra-pure PP resin. Crude Oil Prices
SK has a license contract with British recycling company Plastic Energy for pyrolysis, a technology that converts plastic waste into crude oil through high-temperature heating with limited oxygen. Plastic items, such as baby bottles and interior materials for vehicles, are made using crude oil.
SK Innovation, SK’s energy unit, plans to use the pyrolysis oil as feedstock for its naphtha cracking by refining it using the post-pyrolysis processing it has developed.
Green hydrogen: the future of sustainable energy at your fingertips
Green hydrogen is a clean and abundant energy source that is rapidly transforming the way we meet our energy needs. With falling costs and optimistic forecasts, green hydrogen could soon become an everyday reality, helping to reduce carbon emissions and ensure a cleaner future for our planet. Crude Oil Prices
- Green hydrogen produced from renewable sources is expected to become competitive with gray hydrogen derived from methane or industrial waste in existing plants by 2030 in at least five key markets.
- New green hydrogen projects will become cheaper than keeping existing gray ones running in Brazil, China, Sweden, Spain, and India by 2030.
- Brazil will get the lowest cost for green hydrogen by 2023, estimated at $1.47 per kilogram.
- By 2050, the cost of newly built green hydrogen will be lower than the marginal cost of gray hydrogen from existing plants in all markets modeled.
- Some significant challenges remain for the domestic adoption of green hydrogen, including the high energy requirements for production and the need for a specialized network of electrolyzers and distributors.
- However, there is an interesting prospect for the use of green hydrogen in domestic off-grid. Two German companies have developed systems to produce and store hydrogen at home during the summer, capable of covering winter energy consumption, including heating. Crude Oil Prices
Green hydrogen is a promising solution for the energy transition. While challenges remain in domestic adoption, the use of green hydrogen is gaining momentum, and it is poised to become a driving force in the energy industry by 2030.
In addition to the key takeaways above, I would like to add that green hydrogen has the potential to revolutionize many sectors of the economy, including transportation, industry, and power generation. It can be used to produce clean fuels, chemicals, and electricity. It can also be used to store energy from renewable sources, such as solar and wind power.
Green hydrogen is a versatile and sustainable energy source that has the potential to help us achieve our climate goals. With continued investment and research, green hydrogen could soon become a key part of our global energy mix. Crude Oil Prices
Recycled products and development trend in Yarn Expo Autumn 2023
Yarn Expo Autumn 2023 is held in Shanghai during Aug 28 and Aug 30. The Yarn Expo has decent popularity, although it is slightly less popular than the Yarn Export held in spring in the first half of the year. The highest level of popularity is observed in 8.2 Hall.
- Market sentiment
Ningbo Dafa and Guangdong Tok Zin raised the HC re-PSF offers by 100yuan/mt on Monday, and then part of plants in Jiangsu raised the HC re-PSF offers by 100yuan/mt and solid re-PSF offers by 50yuan/mt on Tuesday. The price increase this year is mainly pushed by higher feedstock market and sales are divergent. Sales are ordinary in Zhejiang and Jiangsu, and producers show concerns over the feedstock supply and demand in buoyant season later. Crude Oil Prices
1) Market participants worry about the market in buoyant season. Recently, HC re-PSF sales are ordinary, and price increase is sporadic. Producers mainly stand on the sidelines. Part of HC virgin PSF plants lacks advantages, and is hard to compete. A few new production lines are delayed.
2) Boheng specializes in differentiated recycled PSF. Currently, there are 114 colors in their color card, and many of these colors are quite dreamy, especially appealing to niche differentiated customers. The necessity of OBP (Ocean bound Plastic) becomes more prominent with Japan’s release of nuclear wastewater, as the urgent need to save plastic in nearby seas becomes apparent. It is reported that there are only three domestic manufacturers of recycled fibers with OBP certification: Boheng, Zhongyuan, and Cyclone.
Ocean Bound Plastics, abbreviated as OBP, refers to improperly managed plastic waste that is abandoned in the environment, where it can be transported to the ocean through rain, wind, tides, rivers, and floods. Plastic waste in landfills or managed waste facilities is not considered OBP, but plastic waste in uncontrolled informal landfills within 50 kilometers of the coastline is considered OBP. The purpose of OBP is to protect the ocean from plastic pollution originating from land-based activities, rather than recovering plastic from the ocean through fishing or collection efforts.

3) Zhejiang Jiaren continues to expand capacity on chemical recycling, and R-DMT is launched this year.
4) The production process under chemical recycling of Cyclone is below. According to Cyclone, the costs of chemical recycling are 3,000-5,000yuan/mt higher than that of physical recycling.
