In mid-December of 2007, DuPont Dongying Titanium Dioxide Project was known to some people because of a report in Southern Weekend that "DuPont titanium dioxide project was settled in Shandong and was rejected by Taiwan for rejecting environmental protection shortboard." Above: Greenpeace wrote a letter to the Ministry of Environmental Protection and the National Development and Reform Commission for the Dupont Dongying Titanium Dioxide Project. In a negotiation with DuPont China, Greenpeace raised several questions from experts, including the chlorination process. Emissions and treatment methods, as well as potential safety hazards associated with deep well perfusion mentioned in the process, are expected to provide an EIA report to DuPont to have a detailed understanding of the amount of pollution produced, but DuPont China only provides EIA reports. Jane Zhang has never given a positive answer to the concerns raised about pollution hazards. In the simplified version of the EIA report, there is no forecast of the number of POPS that will be produced in the production process, and there is no corresponding precautionary measure. DuPont China refused to provide the full EIA report on the ground of "preventing leakage of trade secrets," and Yue Yihua, the leader of the Greenpeace pollution prevention project, reluctantly stated, "We have no intention of gaining access to their trade secrets. Some of his technical data, but our most requested pollutant emission information should definitely not be a trade secret, and we mentioned at the time that if you think there is a trade secret, you can hide those parts and show us, but they did not Respond."
Di-tertiary Butyl Peroxide is an organic compound consisting of a peroxide group bonded to two tert-butyl groups. It is one of the most stable organic peroxides, due to the tert-butyl groups being bulky. It is a colorless liquid.
DTBP can in principle be used in engines where oxyge is limited, since the molecule supplies both the oxidizer and the fuel
DTBP is an irritant to noses, and eyes and skin. It is also flammable, so it should be handled with care.
DTBP is a liquid dialkyl peroxide. It is an efficient initiator for polymerization of olefins and
acrylic resins, and a modification agent of PP degradation, insoluble in water, soluble in
organic solvents such as toluene, acetone, styrene, etc. Freeing point lower than -30℃.
Miscible in alcohol,esters,ethers,olefins and othe organic solvents Immiscible with water.
20kg jerrycan,160kg steel PVF drum.Store in -30℃-40℃ with efficient air ventilation. Avoid direct sunlight.

In January 2008, “Southern Weekend†once again tracked several disputes in the Dupont Dongying project. Greenpeace, the international environmental protection organization, began to intervene in the investigation and intervention of the project.
Sun Yuanzhi, a researcher of the Institute of Process Engineering of the Chinese Academy of Sciences and a member of the chlorination titanium dioxide research group of the Ministry of Chemical Industry, wrote a proposal on “Several Opinions on the Dupont Dongying Titanium Dioxide Factory Project†and transferred it through Greenpeace in April 2008. The Department of Environmental Assessment of the Ministry of Environment and the Industry Development Department of the National Development and Reform Commission responded that they received. When the NDRC replied, it stated that the project was highly controversial and would consider various opinions in an integrated manner. However, there was no news afterwards. It was later learned that in November 2007, the Environmental Assessment Department of the Ministry of the Environment had already passed the EIA of the project. According to speculation, in April 2008, the project had not been approved by the NDRC. 
On June 27, 2008, Greenpeace Yue Yihua once again stated his viewpoint: "In addition to the several concerns raised by Professor Sun, there are two additional supplements. As long as the project has not yet been finalized, we have the opportunity to raise our doubts. And suggestions, hope to be improved, to eliminate these environmental pollution from the source."
Greenpeace added two concerns about the project:
The first is for the emission of emissions. The production process of the chlorination process will inevitably lead to the development of the two-fold. Second, the British government is bound by the Stockholm Convention, and the world should adopt all measures to disable one of the 12 types of persistent organic pollutants (POPs) that are the most toxic. The purpose is to prevent and deal with the Basel International Convention on the Control of Hazardous Wastes that has been transferred to the developing countries that are less able to control them. This includes the following provisions: “States Parties shall take appropriate measures: Ensure adequate disposal facilities for hazardous wastes and Environmentally sound management of other wastes, regardless of where they are located, and where possible, these facilities should be located within the national territory; "The essence of the Basel Convention is to discourage the transboundary movement of hazardous wastes, although it is also Some exemptions are designed to increase operability, but there is absolutely no reason to encourage the export of hazardous waste within the exemption clause. Even if DuPont claims that its persistent organic pollutants (POPS) content is within legal limits, DuPont is also violating the spirit of the Basel Convention and transferring a technology that generates POPS waste to developing countries for production.
DuPont does not publicize the extremely dangerous toxic substances that are produced in the production process. It does not tell the public how it plans to dispose of this waste, and how to protect the environment and public safety of the communities in which it operates. This is definitely not a manifestation of respect for the right to information of the public (The description of persistent organic pollutants on the seventh page of the simplified version of the EIA report does not contain any specific information. It does not make any predictions about the amount of POPS produced by the Dongying project. Prevention measures).
In DuPont's home country, the United States, according to the "Emergency Planning and Public Access to Information Act", every DuPont factory needs to release its series of toxic substances released to the public. The right to know the public is a prerequisite for the public to participate in environmental protection. This right of the public has no national boundaries, and it will not be different because of the degree of legal perfection in each country. For DuPont, a company with many years of mature operating experience in the United States, it is surprising and incomprehensible to visit China and ignore the Chinese public’s right to know.
The second is about the deep well perfusion method. DuPont is the so-called pioneer in dealing with waste problems with deep well infusion methods. The Greenpeace position completely opposes the treatment of such waste. Its method of burying hazardous waste deep underground not only poses great risks to the environment in the future, but also completely fails to meet the principle of “clean productionâ€. In the face of hazardous toxic wastes, manufacturers should strive to completely eliminate the production of toxic substances from the perspective of improving the process, and it is never to be proud that these toxic substances are buried underground.
In addition, Yue Yihua also disclosed his own concern that if the DuPont Dongying Titanium Dioxide Project does not take active response measures and does not respond to and improve any experts’ environmental protection queries, it will be passed, to a certain extent, It will encourage other international agencies to enter China in a similar manner. In addition, the deep well perfusion method mentioned in the project will, to a certain extent, encourage other domestic polluting companies to adopt a similar approach to smothering sewage.
