CNOOC’s carbon dioxide-degradable plastic project comes online
Thread Content
The production facility for 3,000 tons per year of carbon dioxide-degradable plastics, invested in and built by CNOOC Investment Holding Co., Ltd., has recently started operations successfully and is producing qualified products. The total investment in this project was 152 million yuan, and construction began in July 2007. The project utilizes world-leading patented technology independently developed by the Changchun Institute of Applied Chemistry, Chinese Academy of Sciences, with CNOOC Chemical Co., Ltd. being entrusted with the project construction and production operation management. The project makes full use of the resources such as water, electricity, and steam available from the existing facilities in the Dongfang Industrial Park, using the carbon dioxide emitted by these facilities as raw material. Yang Yexin, CEO and President of Zhonghai Chemical Company, said that the successful implementation of this project will enable the direct reduction of 2,100 tons of carbon dioxide per year, helping to achieve the energy-saving and emission-reduction goals set forth, while also eliminating \"white pollution\" and contributing to the development of Hainan as an ecological province. It is reported that environmentally friendly plastic bags made from carbon dioxide-degradable plastics are a first in both China and internationally, representing a breakthrough in the resource-based chemical industry. It is understood that producing 1 ton of plastic for this project requires 0.5 tons of carbon dioxide, with the output value per ton being around 20,000 yuan. To date, CNOOC has identified natural gas reserves of around 2 trillion cubic meters in the Yinggehai Basin in the South China Sea, where the project is located (70% of these reserves contain carbon dioxide). If production scale is expanded, it will significantly reduce the concentrated emission of carbon dioxide from an environmental perspective; it can also replace polluting, non-degradable plastics, thereby creating a more rational and efficient industrial chain that allows for the utilization of by-product waste gases, achieving a \"win-win\" situation in terms of economic benefits and environmental protection.
May the technology for synthesizing biodegradable plastics through the copolymerization of CO2 and epoxides, which relies on the independent intellectual property rights of the Changchun Institute of Applied Chemistry under the Chinese Academy of Sciences, see greater promotion and application. It is unknown what the operating status is of the first production facility to utilize this technology – the carbon dioxide-degradable plastic production plant owned by Mengxi High-Tech Group Company, with an annual production capacity of 3,000 tons It’s been in operation for the 6th year now, I guess.

While other countries are trying every means to bury carbon dioxide underground, we**, on the other hand, extract the carbon dioxide that is already buried there as a resource, while ignoring the large amounts of industrial emissions! Focusing only on immediate gains is, in itself, a failure to take responsibility for the **future!
I am very interested in this project; could anyone provide more detailed information?
Not bad, not bad. Can I learn more about it?
Hehe, saying that might be a bit unfair to “**”. The natural gas resources in the South China Sea are rich in carbon dioxide; this is an inherent characteristic of those resources, and it’s not something we deliberately do to extract CO2 for use. I have been following the progress of this technology at the Changchun Institute of Applied Chemistry, hoping that it will truly bring benefits. Utilizing CO2 is quite challenging; aside from physical methods such as burial and conversion into dry ice for emission reduction, there are currently no truly commercial-scale chemical processes in use. I once conducted research on the production of DMC from CO2 + CH3OH for a period of time; the conversion rate was extremely low, and it was very difficult. For the CO2-rich natural gas in the South China Sea, many studies have explored the direct reformation of CO2 + CH4 to produce syngas, but the economic viability of this technology remains to be assessed and is not very promising. I think using CO2 polymerization to produce polymers is a good option; other than that, we can only rely on photosynthesis carried out by the sun.
It’s the poor quality of the natural gas – it contains too much carbon dioxide – rather than the fact that carbon dioxide can be extracted from it.
These pilot plants are not even capable of reducing the greenhouse effect by any significant amount; they fall far short of that goal. Let’s wait and see. With 2,100 tons being consumed each year, doesn’t CNOOC’s urea plant produce hundreds of thousands of tons of carbon dioxide per year?
Could the original poster provide more details? In the hydrogen production via gasification that I am currently carrying out, there is a large amount of CO2 by-product that needs to be dealt with urgently!
This is a very promising project, and it is hoped that it will be successful and grow stronger, contributing to the reduction of greenhouse gas emissions and the mitigation of \"white\" pollution——
Yes, how is that project progressing? We also want to launch a project related to carbon dioxide.
