    A 2018 report found that food waste would increase by a third to 2. 1billion tons by 2030. Beyond the cost of the waste itself，thrown-away food generates a gas that contributes to climate change.

Home delivery meal kits(盒)can reduce food waste by more than two-thirds，but suppliers need to switch to reusable packaging to make them environmentally friendly.

Tailor-made meal kits cut waste by providing people with precise amounts of fresh ingredients(烹饪原料)for chosen recipes，meaning leftovers are minimized. But while the  delivery services score well on reducing food waste，buying the same food ingredients from the supermarket almost always saves energy overall simply because meal kits use so much single-use packaging. The good news is that if people have meals that are tailored for consumption，they won’t overbuy and have less food waste. They fine-tune the amount of food to what they will actually eat.

Meal kits can reduce transport emissions(排放)if people go to the supermarket less  frequently. If people only go and buy such goods as soap and toilet paper，they may only have to visit once every couple of months. A delivery truck can carry meals for a lot of people in the neighborhood. So dozens of car trips might be replaced with one truck trip.

However，study found that even if delivery meal kits reduced food waste to zero，they would still use up more energy overall than buying the same food from the supermarket unless the energy used for the meal kit packaging was cut by a fifth. The packaging is a killer if it’s single-use and thrown away，which can make all the environmental benefits lost. But if the packaging can be reused，if it’s glass bottles，like in the old days，we can get some benefits.
