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.
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.
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.
Identify palm oil.
Palm oil can be found in nearly 50% of the packaged goods we eat- from cookies, peanut butter, breakfast cereal to cleaning products, laundry detergent, lipstick, and body lotion. It is heavily driving deforestation. Looking at the ingredients it is often hidden in other terms like "vegetable oil" and others. Make sure to look out for labels like RSPO and others.
Avoid parchment paper.
First of all, a lot of parchment paper is bleached and also contains dioxin. Wax paper also consists of paraffin and is derived from petroleum, which is terrible to ingest. Go for silicone mats as they can be reused thousand times, don't stick and cut down oil/fats consumption.
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.
