Food waste (IME) likewise estimated that 30–50% (or ) of all food produced remains uneaten. In Singapore, of food was wasted in 2014. Of that, were recycled. Since Singapore has limited agriculture ability, the country spent about S$14.8 billion (US$10.6 billion) on importing food in 2014. US$1.4 billion of it ends up being wasted, or 13 percent. In the UK, per year of wasted food (purchased and edible food which is discarded) amounts to a cost of £10.2 billion each year. This represents costs of £250 to £400 a year per household. Estimates of food waste in the United States range from
Economic order quantity it is a function of only K, D, h. The optimal value Q* may also be found by recognising that formula_10 where the non-negative quadratic term disappears for formula_11 which provides the cost minimum formula_12 Economic order quantity = formula_13 formula_14 = 400 units Number of orders per year (based on EOQ) formula_15 Total cost formula_16 Total cost formula_17 If we check the total cost for any order quantity other than 400(=EOQ), we will see that the cost is higher. For instance, supposing 500 units per order, then Total cost formula_18 Similarly, if we choose 300 for the order quantity
