The Hidden Cost of Hong Kong's Food Waste (And What We're Doing About It)
Every single day in Hong Kong, about 3,000 tonnes of food ends up in landfill. That's the weight of more than 200 double-decker buses. It's also the largest single category of municipal solid waste the city produces — more than plastic, more than paper, more than glass.
If you've ever opened the fridge to find a bag of forgotten greens turning to mush, you already know how easily it happens at home. Multiply that small moment by 7.5 million people, by every restaurant kitchen, by every wet market stall and supermarket back room, and you arrive at the scale of Hong Kong's food waste problem.
But here's the part that doesn't usually make the headline: the numbers are starting to move in the right direction.And there's a clear, practical role for anyone reading this to play.
Where Hong Kong's food waste actually comes from
The Environmental Protection Department's most recent figures give us a reasonably clear picture:
About 68% of food waste comes from households — uneaten meals, forgotten leftovers, produce that wilted before it got cooked.
The remaining 32% comes from the commercial and industrial sector — restaurants, hotels, food processors, wet markets, and supermarkets.
The average Hong Konger throws away around 71 kilograms of household food waste every year. To put that in context, that's roughly the weight of an adult.
The commercial side gets a lot of attention because it's concentrated and visible. But the real story — and the bigger opportunity — is in the kitchens of ordinary apartments across Kowloon, the New Territories, and Hong Kong Island.
Why it matters beyond the landfill
It's easy to think of food waste as a "rubbish problem." It's actually three problems stacked on top of each other.
1. It's a climate problem. When food rots in landfill, it produces methane — a greenhouse gas roughly 80 times more potent than CO₂ over its first 20 years in the atmosphere. The food sitting in Hong Kong's landfills today is still contributing to global warming long after it stopped being edible.
2. It's a financial problem. Hong Kong households throw away an estimated HK$13 billion worth of food every year. That's roughly HK$1,700 per person, gone.
3. It's a fairness problem. While food is being thrown out, an estimated one in five Hong Kong residents lives below the poverty line, and food insecurity organisations report rising demand year after year. The food being wasted is, in most cases, perfectly edible.
The good news: it's starting to shift
In 2024, the Environmental Protection Department reported a 6% drop in food waste disposal — the average daily quantity fell from around 11,130 tonnes of total municipal solid waste in 2022 to 10,510 tonnes in 2024. Food-waste-specific collection across the city grew from about 200 tonnes per day in December 2023 to roughly 310 tonnes per day by October 2024.
A lot of that progress has come from three places:
Domestic food waste collection at residential buildings, via the Smart Recycling Bin programme.
Charity rescue operations like Feeding Hong Kong, which has rescued more than 8,400 tonnes of food and supplied over 150 frontline charities since 2011.
Tech-driven food rescue platforms that connect restaurants with surplus stock directly to consumers in real time — which is exactly where CHOMP comes in.
What food rescue actually looks like in Hong Kong
A bakery in Sheung Wan finishes service at 8pm with 22 perfectly good loaves left on the shelf. A Japanese restaurant in TST has 14 portions of ready-to-eat curry sitting in the warmer at closing time. A wholesaler in Cheung Sha Wan has crates of slightly-too-ripe mangoes that won't survive another day on the shelf.
In an old model, that food gets thrown out — there's no time, no infrastructure, and no obvious buyer at 9pm on a Tuesday.
In the food rescue model, all of it gets a second life. Apps like CHOMP let restaurants list those items at a steep discount in the last hour of service. A diner gets a great meal for HK$30–50. The restaurant recovers some revenue instead of paying to throw food away. The food doesn't end up in landfill. Nobody loses.
It's not a moral compromise — the food is the same food the restaurant sold at full price an hour earlier. It's just a smarter way to match supply with demand.
How you can be part of the fix
Three concrete things, in increasing order of impact:
Audit your own fridge once a week. Spend five minutes on a Sunday checking what's in there. Plan one meal that uses up the items closest to expiry. This single habit cuts most households' food waste by 20–30%.
Cook with the "stem-to-leaf" principle. Carrot tops make pesto. Broccoli stems make slaw. Stale bread becomes croutons or breadcrumbs. The flavour is there — it's just been thrown out for decades.
Use a food rescue app at least once a week. A single Surprise Bag from a partner restaurant prevents a few kilograms of food from going to landfill and saves you 50–70% on a meal.
Where this is heading
Hong Kong is at an interesting moment. Mandatory municipal solid waste charging has been deferred but is still on the policy roadmap. The government's organic waste treatment facilities (O·PARK1 and O·PARK2) are now turning food waste into biogas and compost. Domestic food waste collection is scaling. And consumer awareness — especially in younger demographics — is climbing fast.
The piece that's still under-built is the last mile of food rescue: the moment a restaurant has surplus and someone nearby has dinner plans. That's the gap CHOMP exists to close.
If you'd like to see what that looks like in practice, our next Rescued Feast dinner is happening soon — a community meal where every dish is built from rescued ingredients sourced from CHOMP partner restaurants, farms, and suppliers across Hong Kong. It's part dinner party, part demonstration of what's actually possible.
