Project Overview

Current Situation: The year 2026 marks the inaugural year of the "15th Five-Year Plan" and the first year of the transition from dual energy-consumption control to dual carbon-emission control. The dual-carbon strategy has become a new engine for green-development-driven economic growth. Mengniu has established the targets of "carbon peaking by 2030 and carbon neutrality by 2050," incorporating sustainable development into its core strategy and leading the industry through green transformation. This enterprise has adopted strategic deployments at all levels, building a comprehensive dual-carbon management system, strictly controlling energy use, upgrading production processes, and leveraging digital tools for refined carbon-emission management, effectively driving green development to deliver tangible results. Cause Analysis: To systematically advance the construction of a zero-carbon factory, we have established a full-chain closed-loop system of "inventory – reduction – offset – certification." First, comprehensive carbon inventories were conducted to establish baseline emissions. Second, deep emission reductions were implemented at key process points as the core of the effort. Third, remaining unavoidable emissions were neutralized through compliant carbon offsets. Finally, third-party authoritative verification and certification were obtained to ensure compliance and credibility throughout the entire process. Improvement Objectives: In alignment with the national comprehensive energy-conservation and emission-reduction strategy, and in support of Mengniu's "dual-carbon" targets, this enterprise has adopted strategic deployments at all levels, building a comprehensive energy-conservation and emission-reduction management system. We strictly control energy use, upgrade production processes, and leverage digital tools for refined carbon-emission management, effectively driving green development to deliver tangible results. Sustainable development is incorporated into the core strategy, leading the industry through green transformation.

Project Implementation

1. Refrigeration Energy Consumption Optimization Project Approach: Cold energy meters were installed to enable precise metering, detailing cooling data by zone and production line. The traditional extensive energy-supply model was replaced with demand-driven dynamic adjustment. A fair and transparent cost-allocation model based on actual cooling consumption was established. Calculation Method: ① The enterprise used the 2025 electricity consumption statistics as the data source for accounting. Year-over-year comparison showed that single-ton ice water could save 31.76 kWh of electricity, with annual savings of 248,015.38 kWh. ② Based on the "2022 Electricity Carbon Dioxide Emission Factors" (Announcement No. 33 of 2024 by the Ministry of Ecology and Environment and the National Bureau of Statistics), the average electricity carbon dioxide emission factor for Sichuan Province is 0.1404 kgCO2/kWh, from which the annual carbon-emission reduction was calculated. Results: The project saves approximately 248,015.38 kWh of electricity per year, with an annual carbon-emission reduction of approximately 34.82 t/a. 2. Boiler Steam Output Improvement Project Approach: The boiler start-stop pressure differential was adjusted from the original 0.05–0.1 MPa to 0.1–0.15 MPa to scientifically match operating conditions. Through parameter optimization, daily start-stop cycles were reduced from 20 to 5, eliminating wasted energy. Irregular daily blowdown was standardized to a fixed 4 times/day, reducing heat and water losses. Calculation Method: ① The enterprise used the 2025 natural gas consumption statistics as the data source for accounting. Year-over-year comparison showed monthly savings of approximately 800 m³ and annual savings of approximately 9,600 m³ of natural gas. ② Based on the natural gas CO2 emission factor for the corresponding industry from the "National Greenhouse Gas Emission Factor Database," the annual carbon-emission reduction was calculated. Results: The project reduces steam consumption by 15 tons per month, yielding savings of 15 × 243.72 RMB/ton = 3,600 RMB. Natural gas savings: 9,600 m³/year. Annual carbon-emission reduction: 20.75 tCO2/a. 3. Pre-treatment CIP Water Usage Optimization Approach: The cleaning program was modified to change "pumping acid to tank top" to "pumping hot water to tank top." Before introducing acid solution, hot water is used to push residual water in the pipeline into the tank, eliminating waste at the source and achieving 100% effective recovery of pipeline residual water. Calculation Method: The enterprise used the 2025 water consumption statistics as the data source for accounting. Year-over-year comparison showed savings of 0.4 tons of water per cleaning cycle, with approximately 800 CIP cleanings per month, from which annual savings were calculated. Results: The project saves 0.2 tons of water per cleaning cycle, with 8 tanks per day, amounting to 320 tons per month and 3,840 tons per year. Wastewater discharge is also reduced by 3,840 t/a. 4. YoyiC Tank Cleaning Temperature Optimization Approach: The program was modified to change the cleaning-temperature timing judgment for YoyiC tanks (mixing tank, fermentation tank, holding tank, filling machine) from CIP station return-line temperature to tank-body temperature. Each cleaning cycle is shortened by 4–8 minutes. With the cleaning circulation pump power at 7.5 + 7.5 kW, each cleaning saves approximately 1–2 kWh. Calculation Method: ① The enterprise used the 2025 electricity consumption statistics and cleaning circulation pump power for accounting, calculating per-cycle, monthly, and annual electricity savings. ② Based on the "2022 Electricity Carbon Dioxide Emission Factors" (Announcement No. 33 of 2024 by the Ministry of Ecology and Environment and the National Bureau of Statistics), the average electricity carbon dioxide emission factor for Sichuan Province is 0.1404 kgCO2/kWh, from which the annual carbon-emission reduction was calculated. Results: The project saves 1–2 kWh per cleaning cycle, with approximately 200 cleanings per week, 800–1,600 kWh per month, and 9,600 kWh per year. Annual carbon-emission reduction: 1.35 t/a.
