Beyond the bin: recovery and upcycling of food waste

In our daily lives, over-purchasing, cooking in excess, or leaving restaurant meals unfinished can all result in food waste. When these organic materials are sent directly to incinerators, they not only increase the burden on waste management systems but also represent a missed opportunity to repurpose valuable resources.

Reduce waste at the source

The simplest and most effective way to reduce food waste is to prevent it at the source. At home, cook only what you need; when dining out, order mindfully to avoid leftovers. If you do have extra food, sharing it with friends or family is a great way to ensure it doesn't go to waste. When disposal is unavoidable, proper recycling is essential. Simply drain any liquids and follow local government guidelines to boost recycling efficiency. Finally, keep unidentified meats or non-recyclable items out of food waste bins to maintain the quality of the recycling system.

Transforming food waste into sustainable value

The cornerstone of food waste recovery lies in proper sorting at the source. By categorizing waste into cooked and raw types, we maximize its reuse potential:

  • Cooked food waste (animal feed): includes grains, noodles, soy products, snacks, canned goods, and leftover meals.
  • Raw food waste (composting): includes vegetable scraps, fruit peels, seeds, and organic residues (e.g., tea leaves, coffee grounds).

Note: for detailed information, regional regulations and local recycling initiatives, please refer to the websites of the respective environmental protection departments and bureaus.

Food waste is a misplaced resource, not "trash." Beyond traditional feed and compost, modern technologies such as anaerobic digestion can also be converted into green energy through anaerobic digestion for power generation, or black soldier fly farming are revolutionizing the resource circulation. These innovations not only reduce the load on incinerators but also advance the circular economy, ensuring that food waste is properly reused.

The administration encourages every household to embrace these practices. Through our collective efforts, we can optimize the food waste circular system and ensure environmental sustainability.
