2014-2017 SYTECH Environmental Protection, Energy Saving and Emission Reduction Related Data Disclosure

Environmental Protection (2014-2017)

In 2014, Plant Five in Wanjiang applied high-efficiency microbial active bacteria purification technology to comprehensively treat incinerator exhaust, achieving ≥50% nitrogen oxides (NOX) reduction, ≥80% sulfuric acid mist (including sulfur dioxide) deduction and ≥90% organic substances (VOC) reduction. Total hydrocarbon value of non-methane meets the relevant national environmental discharge requirements.

In 2015, Plant Five in Wanjiang applied biological enzyme technology and high-pressure spray principle to deodorize the incinerator exhaust. After the improvement, we greatly reduced odor and irritating taste and effectively reduced surrounding complaints.

In 2015, Plant Four in Wanjiang applied high-efficiency ultra-fine recombination organic waste purification technology to deodorize the incinerator exhaust. After the improvement, we reduced the odor to a better extent and the exhaust gas meets the secondary factory standard value of the Environmental Air Quality Standard and the secondary factory standard value of the Odor Pollutant Discharge Standard.

In 2016, Plant Four in Wanjiang applied UV photolysis technology to reduce VOC of the incinerator exhaust. With the improvement, we achieved ≥80% organic substances (VOC) reduction.

In 2017, the catalytic combustion technology is used to further control the exhaust of the incinerator of Plant Five in Wanjiang and Plant Four in Songshan Lake. The treatment efficacy is 60%-70% and the non-methane total hydrocarbon concentration is further reduced on the basis of compliance.

In 2017, light microwave technology is applied to comprehensively control the exhaust gas of each vacuum pumping station in Songshan Lake Plant. While we reduce the concentration and emission of non-methane total hydrocarbons, the exhaust gas also meets the factory standard value of Odor Pollutant Discharge Standard.

Energy Saving and Emission Reduction (2014-2017)

In 2016, the implementation of the joint control of the cold water system in Plant One and Two in Songshan Lake further improves the operational energy efficiency, saving 53.4 tons of standard coal and reducing carbon emissions by 138.8 tons per year.

In 2016, we changed the traditional energy-saving lamp lighting mode and fully applied LED lighting, saving 78.7 tons of standard coal and reducing carbon emissions by 204.6 tons per year.

In 2015-2016, we fully applied and implemented the centralized control system technology of air compressors, saving 124.7 tons of standard coal and reducing carbon emissions by 324.1 tons per year.

In 2015, through reasonable production allocation of the prepreg orders, the equipment of Plant Three in Wanjiang with high energy consumption was shut down, and the orders were transferred to Plant Four in Songshan Lake, the energy consumption of which is lower so as to reduce energy consumption. We save 170.1 tons of standard coal and reduce carbon emissions by 442.3 tons per year.

In 2014, we implemented waste heat utilization transformation of the hot oil boilers of some pressing machines, thereby reducing boiler fuel consumption, saving 40.5 tons of standard coal and reducing carbon emissions by 105.3 tons per year.

In 2014, by applying a variety of optimization measures, including wind frequency automatic adjustment technology, the establishment of incinerator abnormal control standards and emergency measures, optimization of the circulation throttle action and the introduction of RTO automatic monitoring reminder system, fuel consumption of the treaters continues to decline, greatly reducing the fuel consumption per kilometer of prepreg, saving 173.6 tons of standard coal per year and reducing carbon emissions by 451.4 tons.

Through the transformation of the storage tank system in Songshan Lake, we reduce breakpoints in the manufacturing process, achieve seamless connection in the pre-dissolved, reduce labor and material consumption, greatly improve inventory security and save 5.18 million RMB per year.

Through transforming the clamping shaft unit, we realize automatic operation, and save glue by about 10 tons per year.

By adding broken cloth alarm device to the treater, we reduce the annual loss of broken cloth by 6095 meters per year.

We apply grid-connected and series of optimization and transformation measures to transform the frozen water machine room of Plant One in Songshan Lake, saving 610,000 kWh of electricity per year, corresponding to the electricity cost of 520,000 RMB, and achieving good economic benefits.

We apply automatic identification and calculation of cold load and automatic adjustment technology to transform the frozen water machine room of Plant Three and Four in Songshan Lake. After the transformation, we reduce 1.6 million degrees of the annual electricity consumption, saving electricity costs of 1.38 million RMB, and the benefits are remarkable.

We transform 1#RTO of Plant Three in Songshan Lake into diesel and natural gas dual-use (mainly used natural gas before) to further improve combustion efficiency and reduce energy consumption by about 60,000 RMB per year.

We participated in the power bidding transaction project in 2017, saving 5.3 million RMB in electricity costs in the same year for the company.

In 2017, through management improvement, the company's various energy consumption indicators have decreased compared with 2016, saving 2.8 million kWh of electricity, 140,000 m3 of gas consumption, and a total of 2.53 million RMB.
