CIRCULAR
ECONOMY
By transforming waste into renewable energy, we power a more sustainable future for our industry.
Since 2012, we have operated one of the green energy cogeneration plants in sugar mills in Mexico.
The purpose of this project is to generate renewable energy from biomass waste available in bagasse, which is produced during the sugar manufacturing process.
FEATURES OF COGENERATION
- The plant is located at Tala Mill in the state of Jalisco.
- Operated 100% with sugar cane bagasse to produce renewable energy.
- Installed capacity of 78 MW; generating more than 290,000 MWh each year.
- Annual consumption at Tala Mill is 92,000 MWh, while the remaining 200,000 MWh are supplied to industrial partners.
BENEFITS OF COGENERATION
- In the last 5 years, we have reduced CO2 emissions by 30%, which means an improvement in the environment, the quality of life of local residents, and the well-being of mill workers.
- Creation of approximately 450 temporary jobs and hiring of various services during the two construction phases.
- Zero fossil fuel consumption in the sugar production process since 2012.
- Energy efficiency reducing 7% of total consumption per harvest.
- Generation of 19.5 MW of clean energy during the harvest period.
- This plant serves as an energy platform as the basis for an ethanol production project.
PRODUCTION PROCESS
One of the main challenges faced by agricultural activity in Mexico is proper waste management.
At Siembra, we make use of filter cake, soil, ash, vinasse, and organic waste to process them and produce high-quality compost.
WITH THE APPLICATION OF COMPOST WE COUNTERACT SOIL DEGRADATION
- Improves soil structure and nutrient retention
- Enhances fertilization efficiency
- Improves moisture retention and water absorption
- Increases beneficial microbial populations and suppresses soil pathogens
- Provides plant resilience against adverse climates
- Improves yields and field productivity
- Reduces the use of chemical fertilizers
We optimize, reuse, and harness the water from our sugarcane processes to ensure sustainability, avoiding the use of external water sources
- We capture water from sugarcane to reuse it in the sugar production process
- We treat water from mill services for reuse
- We capture and treat rainwater
- We eliminate untreated water discharges into federal water bodies
