Organic food waste that goes to a landfill ferments and releases toxic methane into the atmosphere. In the ten years after it is released, methane is 80 times more powerful a greenhouse gas than CO2. It retains many times more heat in the atmosphere than carbon dioxide, and is therefore significantly more damaging from a climate perspective.
Composting is a great way to reduce kitchen waste, and there are many options like worm farms, traditional compost heaps or Bokashi bins to name a few.
Some local governments even provide subsidies, rebates or other incentives for composting. Check in with your local government office for more information.
Even better, once you start, teach three neighbors. Systems problems require systemic solutions.
