Landfill methane is a gas that is produced in a landfill because the things in the landfill undergo anaerobic decomposition. A compost pile, on the other side, undergoes aerobic decomposition. Because it is exposed to oxygen, either by turning it or through the use of worms and other living organisms, it produces CO2 (carbon dioxide) instead of methane.
If you going to create or do compost you can drive incredible impact, but before you do so, please inform yourself on how to do it properly.
Especially if you don't have a garden indoor farming is a great way to grow herb, vegetables and fruits yourself. These techniques dont require soil, so its very clean. You can go for Hydroponics (nutrient rich water solution), Aquaponics (Fish-tank combination for full cycle) or Aeroponics (nutrient rich fog solution) systems.
Compost indoors, with Bokashi.
You don't need a garden or yard to compost. Bokashi composting is a process of fermentation that converts all food waste into compost in 4 to 6 weeks. Perfect for meat, fruits and veggies. It will be a great for soil and plants outside afterwards and you really made a personal impact.
Don't shop when hungry.
Being hungry when grocery shopping will make you have cravings and buy stuff that you don’t need - which will create waste. Plan your meals, make a shopping list and stick to it.
Find your local farmer.
If you have a farmer in your area get in touch with him and see if and what you can purchase directly from him. You will not just support your local economy, reduce footprint but also get a better sense of where your food is coming from: and most importably access high quality local vegetables, fruits, milk or meat.
Reflect on delivery.
Often times it's more sustainable to go into the store or restaurant or pick up the item or food yourself. You will avoid unnecessary packaging and potentially transportation emission from delivery. This depends obviously on distance and type of transportation you would use, since otherwise delivery can be actually more efficient, especially when the providers is running on electric mobility and multiple deliveries are carried.
One effective way is to eat less animal related food like meat, milk, cheese or eggs - especially red meat (cows/labs). Meat lovers have a yearly footprint nearly double compared to vegetarians. 🍆
Organic farming for crops and vegetables has a lower environmental impact compared to conventional methods. Since fertile soils that are full of nutrients, organic food is usually also better for your health.
Eating food which is in season causes less emissions as the food has has not to be produced in heated greenhouses or has to be transported from far way - as distance matters a lot. Especiall avoiding hothouses and air freight can reduce dient impact by 10%.
Save food by local sharing.
If you notice that you will not be able to eat food before it turns bad or have cooked too much, share it! Share it with your neighbourhood or alternatively try the "Too Good to Go" App.
Transportable food container.
When you take away food from a restaurant, take away leftovers or take your own food to work consider to use a durable and reusable food container. By that you can decrease your waste a lot! Also great if you want to buy at a "package-free grocery store".
Homemade stock from leftovers.
Scraps from carrots, tomato, pepper, parsnip, onions, celeryare and others (besides broccoli, cauliflower and brussel) are the foundation for a great stock. Store them into a container and into the freezer. At a later point have it boil and simmer it for 30min together with water and you have a great stock.
