leftover meals
About 50% of a school's daily waste is food. All this can be composted. Paper and cardboard make up almost 30% of a school's waste. Recyclable plastic and glass makes up 15%.The remaining 5% is made up of non-recyclable plastic bags etc.
Organic waste, such as food scraps and yard trimmings, tend to make up the largest percentage of waste produced by households and businesses. These materials can be composted to reduce their impact on the environment.
Yes. Animal waste, known as manure, has been used as fertilizer for thousnads of years. For best results it is composted first, which helps kill off weed seeds in the manure.
Biodegradable waste in a school would be mostly food and vegetable scraps. These can all be composted, fed to chickens, rabbits, guinea pigs and other animals, or used in a worm farm. These are all good ways of converting biodegradable waste into something useful.
The faster it is composted, the less smell. And gardeners want to use compost to help their plants. They would rather make compost than buy it.
Environmental impact is a reason for not composting food waste in home composters. Kitchen garbage disposal systems such as in-sinkerators move food leftovers and scraps to a wastewater plant that removes the largest solids for processing by micro-organisms or into fertilizer to relegation to landfills. They result in high water usage and water treatment.
Manure is an example of a compost. At one point in time the manure was waste. The waste is composted and turns into a nutrient rich soil. This is compost.
A animal could eat the waste and think it's food and the animal could die.
Most of the food has been eaten, and the remainder will be composted.
Non or slow biodegradable wastes such as bones, greasy kitchen waste and non recyclables. Everything else goes into separate waste storage bins and is recycled or composted weekly. Our farm with four adults produces less than 10lbs (5 kilos) of waste for a landfill every two weeks.
Because that food could be going to the hunger
The difference is that biodegradable means that items such as food waste, garden waste and certain plastics can be broken down by the actions of bacterium, fungi and other living organisms. They can be composted. Recycled means that they can be reused as they are once cleaned, processed or treated eg clothes, paper, card and glass.
