The Benefits and Process of Composting Food Waste
TLDR Composting food waste is a simple and inexpensive process that helps reduce methane production in landfills and extends the lifespan of landfills. By adding organic waste, soil, water, and air, composting creates a nutrient-rich fertilizer called humus that improves soil quality and benefits plants.

Composting food waste helps reduce methane production in landfills and extends the lifespan of landfills.

Composting is a simple and inexpensive process that involves adding organic waste, soil, water, and air to create a nutrient-rich fertilizer, and it's important to introduce oxygen to prevent the production of methane.
10:53
Composting is a process of breaking down organic waste into fertilizer called humus, which is done by microorganisms that eat and break down the waste, and it can be done passively or actively depending on how often the pile is turned and managed.
15:55
Composting structures can be built or bought, with options including a single bin system or a three bin system, and some structures even have a crank to turn the compost.
20:52
The hosts discuss what kind of junk you want to throw in the compost pile, including kitchen waste, banana peels, apple cores, orange rinds, and coffee grounds.
25:34
You can throw napkins, newspaper, watermelon rinds, leaves, and trimmings from shrubs into the compost pile, but avoid putting in whole corn cobs, night soil, pet waste, disease garden plants, and invasive weeds like Buttercup's Morning Glory and Quackgrass.
30:31
Meat and dairy products, as well as pesticide-treated plants, should not be composted because they do not decompose and can generate disease-bearing pathogens.
35:27
The ideal composting scene requires a proper carbon to nitrogen ratio of about 30 to 1, with green and recently deceased materials being high in nitrogen and brown and dried materials being high in carbon, and it is important to avoid having too much nitrogen or carbon in order to prevent stinky piles and promote the growth and metabolic activity of the microbes.
40:52
Managing a compost pile involves regular turning, keeping it moist but not soaking wet, introducing oxygen through PVC pipes or earthworms, and understanding the role of microbes, bacteria, fungi, and other organisms in breaking down the organic waste.
46:02
The composting process goes through three stages: the mesophilic stage, where temperatures reach around 40 degrees Celsius; the thermophilic stage, where temperatures reach 50 to 60 degrees Celsius; and the curing phase, where the temperature decreases and the compost becomes nutrient-rich humus.
51:11
Composting can be used to create nutrient-rich humus that improves soil quality and benefits plants, and it can also be used for curbside composting pickup and food waste disposal.
