In 2021, the "Yueqing Ready-mixed Concrete and Mortar Enterprise Pollution Remediation and Improvement Refinement Requirements" will be implemented, which has become an environmental protection "mobilization order" to promote the practice of green production and construction in the Yueqing ready-mixed concrete industry. "For five-star concrete enterprises", the relevant person in charge of the Yueqing Branch of Wenzhou Ecological Environment Bureau said, "taking the lead in promoting the use of new energy mixer trucks in the concrete industry in Yueqing and even Wenzhou City, it is the efforts of the five-star concrete company to comply with the requirements of the development of the new era and low-carbon, energy-saving and emission reduction, and also make a good start for green transportation." ”
Yueqing Five Star Concrete Co., Ltd. was established in 2009, after years of development, has become the "leader" of the construction industry. The company specializes in the production of concrete series products, with an annual production capacity of 800,000 cubic meters and an output value of nearly 200 million yuan in 2023.
Walking into the five-star concrete batching plant located next to National Highway 104 in Putou, Yandang Mountain, several mixer trucks are operating at the same time, among which 3 concrete mixer trucks with huge black battery boxes are particularly eye-catching among many diesel mixer trucks, and the sound of its "zizi" motor is in stark contrast with the sound of "rumbling" diesel engines.
Concrete mixer trucks are heavy-duty engineering vehicles, which are the most basic equipment in the construction industry, but these heavy-duty diesel trucks have also become the "hardest hit area" of carbon emissions due to high fuel consumption, high exhaust emissions and high frequency of use. In November 2022, Five Star Concrete purchased three pure electric concrete mixer trucks with a total value of 4.5 million yuan. "Judging from the current use, the electric mixer truck is quiet and environmentally friendly, without the vibration and noise and exhaust emissions caused by the engine, and the starting and acceleration power has also been significantly improved. Cui Zheng, chairman of Yueqing Wuxing Concrete Co., Ltd., said that a major advantage of pure electric mixer trucks is its economy, the operating cost of replacing heavy trucks is only one-fifth of that of fuel heavy trucks, and each pure electric concrete truck will reduce about 340 tons of carbon dioxide emissions per year.
As the main building materials, concrete and ready-mixed mortar are popularized, used and developed rapidly, and the demand for concrete for public construction projects and private residential buildings has increased exponentially, and the market prospect is broad. As the first concrete enterprise in Yueqing to be approved as a national high-tech enterprise, Five Star Concrete will continue to improve the raw material supply system, from material selection and testing, mixing formula to on-site pouring, etc., layer by layer, strict and rigorous, to be meticulous and keep improving. The company will also continue to expand the scope of market operations and go all out to provide high-quality services for the construction of key urban projects.
Over the years, the Yueqing Branch of Wenzhou Ecological Environment Bureau (hereinafter referred to as Yueqing Branch) has focused on decomposing 15 detailed requirements such as "material sealing, clean transportation, wastewater collection and disposal, standardized storage of solid waste, and dust reduction in the plant" according to the characteristics of the company's industry, focusing on decomposing 15 detailed requirements such as "material sealing, clean transportation, wastewater collection and disposal, standardized storage of solid waste, and dust reduction in the factory area", and helping the enterprise to scientifically standardize the rectification through centralized training, household guidance, spot checks, etc., and comprehensively promote the air pollution prevention and control work of the enterprise. It is reported that the company has invested tens of millions of dollars to transform and upgrade various environmental protection facilities and equipment, equipped with advanced noise, dust online monitoring system, noise and dust more than 85% of the control value, immediately run spray noise reduction, dust reduction equipment, solid and effective promotion of green production.
In the future, the Yueqing Branch will continue to support the enterprise to increase investment in green and low-carbon development, effectively solve the problems encountered in the green and low-carbon development of the enterprise, encourage and guide more enterprises to actively respond, practice and promote the cleanness of engineering vehicles, take the road of energy conservation and consumption reduction, green and low-carbon development, and promote the high-quality development of Leqing quality productivity.
