We have been weighing the food that goes into the fridge every week. Here is the result after 6 months, with an average of 105kg/week:
We got more food over the summer because there were fewer students around, and Tesco does the same order regardless of student numbers. The low points coincide with a key volunteer going on holidays.
This is the MINIMUM amount of food, as food that is delivered to rough sleepers on the way between Tesco and the fridge (probably 5-10kg/wk of fruit, pastries, salads etc.) does not get counted, nor does food brought to the fridge sporadically by individuals (e.g. eggs from the chicken farm that takes our surplus bread). Compost no longer gets counted as the reverend who takes the compost out does not weigh it… but it anyway never accounted for much and still doesn’t.
