The ESI team estimated the annual carbon emissions from food wastage by extrapolating the monthly average offsets.

The data was used to calculate the annual carbon emissions associated with the consumption of each resource. The
conversion ratio for each resource was used to calculate the carbon emissions. The carbon emissions were then summed up
to obtain the total carbon emissions associated with the annual resource consumption. at Knots Café. Resource consumption
conversion factors used included:

• Water = 1.43kg CO2/m3
• Plastics = 6kg CO2/kg
• Food = 5kg CO2/kg

Table 1 shows the consumption of resources on an annual basis at Knots café.

Through collaboration with Knots Café, the ESI team devised Collection and donation of meat offcuts
eco-friendly solutions to address food wastage of offcut
meats. Meat offcuts were collected from Knots Café for donation
to the organisation, Helping Hand, where they can be
repurposed, for example, into pet food. Approximately 20kg
of meat offcuts are collected monthly from the cafe 40 kg of
food waste, potentially saving 1,200kg of CO2 emissions.
