Have you thought about where all your waste goes? Well, the collectors make sure the trash does not cause environmental issues. For instance, filling up landfills affect wildlife since most dump sites are near wildlife habitats.
Where Does Trash Go After Pick up from Your House?
Your Skip collector usually collects your waste with a lorry and travels to the rail transfer stations. At the transfer station, the waste undergoes sorting to different types according to the method of disposal. The waste that will undergo recycling is put aside from those that will end up in the landfill. Large waste pieces like appliances, wood and cardboard are also dealt with differently.
After taking out the large items from the pile of waste, the remaining goes into the conveyor belt. The goal is to separate the trash further and place them in bags. Sometimes the employees physically separate the waste. For efficient sorting, most trash companies employ mechanical techniques. They have trommels and magnets which separate metallic objects from the pile.
At the end of the sorting process, the recyclable materials go to the nearby recycling centres. The metallic objects undergo further separation into different ferrous and non-ferrous metals. They are often sold to scrap dealers. Some companies send furniture, books and appliances in good condition to second-hand stores. The remaining pile may require further separation to make it as clean as possible.
What Happens to Recyclable Materials?
Materials that need recycling include plastics, paper, and cardboard. Usually, the skip company separate recyclable items according to material types. They then undergo further processing to form new products. For instance, plastics can make clothing and fibre filling for duvets. Paper and cardboard become boxes and packaging materials.
What Happens to Food and Garden Waste?
Food and garden waste are used to make compost for farming. The waste sent to compost facilities should be clean and free of non-biodegradable substances. Another conventional method of getting rid of food waste is through anaerobic digestion. The process produces fertilisers sold to local farmers and biogas which is clean, renewable energy.
Energy from Waste
With the increase in environmental awareness, most countries are looking for ways to reduce the use of non-renewable sources of energy. There are facilities which generate power through processing of waste. The energy from waste facilities produces energy in the form of heat and electricity.
What Happens in a Landfill?
General waste that cannot be recycled or compost goes to the landfill. Before being thrown into the dump site, the trash goes into a waste reduction process. The process involves the addition of water and mechanical turning to keep it aerated. The aeration and water speed up decomposition and reduces the volume of waste.
