Apart from technology and all the fanciful machinery used to reduce the impact of food waste, There are also many self-initiated campaigns by businesses and NGOs. One of the most prominent ones is by the Food Bank Singapore. They are a non-government organisation that offer a place for companies and the public to deposit or donate their unused or unwanted food. The food will then be collected and allocated to the needy through a network of member beneficiaries such as family service centres, various types of homes, soup kitchens, and other VWO. As of 2015 they have organised more than 5 programmes in a bid to reduce food waste. One example is the 

The Food Rescue Programme, an initiative to salvage excess cooked foods from F&B establishments by reheating them and redistributing them to poorer households. 

This campaign is also like killing 2 birds with one stone as it feeds the underprivileged as well as prevents food wastage.
