We have reduced our carbon footprint over the last couple of years from 72 880 tonnes of CO2e in 2014, to 66837 tonnes of CO2e at the end of 2015. This is a reduction of 8.29% overall in the Factory. To put it into perspective, this is equivalent of CO2 emissions from 3272 homes’ electricity use for one year.
Our steam usage per year ha/s dropped from 2014 to 2015 from 189.6kg of steam per 1000 litre of product, to 178.8kg of steam per 1000 litre of product. This is a reduction of 5.69% of steam usage. This saving of 10.8 kg of steam per 1000 litres of milk is equivalent to (10.8/1.1) 9.81 litres of water. Thus when producing 1 million litres of milk per day, we save (10800 kg/1.1 Litre of water) 9818 litres of water per day. If the average household in south Africa uses 250 litres of water per day, the water saved per day is equivalent to water usage of (9818/250) 39 households per day.
Our electricity usage has reduced from 2014 to 2015 from 47.1 KWh per 1000 litre of product, to 45.3 KWh per 1000 litre of product produced. This is a reduction of 3.82% in electricity usage. The average hairdryer uses 1500 Watts of electricity. By saving 1.8 KWh of electricity per 1000 litre of milk, which equals to (1.8 x 1000) 1800 kWh per day for producing 1 million litres of milk. But 1800 kWh is equal to 1.8 million watts, thus enough electricity to run (1.8 mil / 1500) 1200 hairdryers simultaneously.
Electricity usage is the biggest contributor to our footprint namely 68%. The use of heavy fuel oils (HFO) is the second biggest contributor at 23% and fuel for vehicles (diesel & petrol) contributes the balance of 8% of our carbon footprint. We are continuing to explore innovative ways to reduce electricity and heavy fuel impact.
Woodlands Dairy’s water use has reduced from 1.61 litre of water per litre of product packed, 1.54 litre of water per litre of product. A reduction of 4.34% in water usage. The saving of (0.07 L x 1 000 000 Litres of milk produced per day) water is about 70 000 litres of water per day. Measuring it again to the average water usage per household in South Africa of 250 litres per day, this is enough water to supply 280 households with water on a daily basis.
