Pillars of Sustainability
Electricity and Energy Consumption
For industrial facilities this refers to feedstock processed. For warehouses facilities, it refers to feedstock handled.
As with CO2 emissions, a decrease in the overall volume of feedstock crushed in 2020 presented a challenge to achieving any reduction in our energy consumption. However, the various improvements, innovations and process changes we executed in our assets made the difference, resulting in a year-on-year reduction of 1.3%, which exceeded the set target.
Around the world, several sites installed a variable-frequency drive (VFD). This is a type of motor drive used in electro-mechanical drive systems to control AC motor speed and torque by varying motor input frequency and voltage, increasing the efficiency of the system. VFDs were installed in San Antonio, US; Pereira, Columbia; Kandla, India; Lampung, Indonesia; Wittenberg, Germany – and at our Brazilian facilities in Ponta Grossa, Jataí and Alto Araguaia.
*The unit of measurement is kilowatt-hours per metric ton (kWh/MT)
Other equipment innovations brought about positive results. In Alto Araguaia, our oilseeds plant in Brazil, an oil recovery system in the soybean hull was implemented, changing the layout of the sieve system in the unit. This led to a reduction in the percentage of oil retained in the hull, from 2.5% to 1.1%. As a result, we were able to reduce the number of fans used in the system, providing an annual reduction in electricity consumption of 1400MWh
Elsewhere, small, systematic steps contributed to constructive incremental change. For instance, in Kandla, India, we began transferring soybean oil from the tank farm to oil drums using gravity, rather than a pump, to save power. And in Tianjin, China, some 300 street lamps in the factory were replaced by LED energy-saving lamps.
