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.
Store and protect food properly.
A super simple but great hack is to store and package your food properly when stored outside or in the fridge with reusable containers to extend the lifetime. Also make sure you safe leftovers.
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.
Choose cloth napkins.
Instead of buying paper towels or Kleenex use cloth napkins and handkerchiefs since they are reusable and have a multipurpose: tissue, hand towel, napkin or snack saver.
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.
