Energy Efficiency Case: Solar-Powered Drying Reduces Carbon Footprint By 37%

The Challenge

Traditional coal-fired tea drying consumes 18.7kWh per kg of tea (China Tea Research Institute, 2022), emitting 12.3kg CO₂. With annual output of 300 tons, our energy costs exceeded $86,000.

The Innovation

In 2023, we partnered with Hubei Energy Group to install 560㎡ solar thermal collectors (ISO 9806 certified). Key technical specs:

Absorption efficiency: 78%

Thermal storage capacity: 3.2MWh

Hybrid backup: Biomass generator (EN 303-5 compliant)

Verified Outcomes

Third-party monitoring by TÜV Rheinland (Report No. CN/2024/ESG-028) confirms:

37.2% carbon reduction – from 3,690 to 2,316 tons CO₂e/yea

26% cost savings – $22,360 reduction in energy expense

Quality enhancement – Infrared drying at 85°C±2°C improves aroma retention (GC-MS analysis shows 15% more linalool)

 

Global Applications

This system suits tea factories in sunbelt regions (＞1,800 hrs sunshine/year). We provide:

Technical blueprints compliant with ISO 50001

Carbon credit certification support (Gold Standard)

OEM equipment sourcing from certified suppliers
