From the start of plastic production through to 2015, the world produced around 6.3 billion tonnes of plastic waste, only 9% of which has been recycled and only ~1% has been recycled more than once. [24] Of the remaining waste, 12% was incinerated and 79% was either sent to landfills or lost to the environment as pollution. [24]
Concrete waste that is rich in alkaline calcium compounds can be used to remove and recover various elements from an aqueous solution. Waste concrete has been used as a sorbent to remove phosphorus from wastewater after the removal of excess sludge in sewage treatment plants. [26] Concrete waste may also be used as an inexpensive gas treatment ...
Ground plastic may be used as a construction aggregate or filler material in certain applications. [141] [142] While generally unsuitable in structural concrete, plastic's inclusion in asphalt concrete, (forming rubberised asphalt), subbase and recycled insulation can be beneficial. [143] An example of this is the construction of plastic roads ...
The first step in aluminium recycling is the collection and sorting of aluminium scrap from various sources. [5] Scrap aluminium comes primarily from either manufacturing scrap or end-of-life aluminium products such as vehicles, building materials, and consumer products. [5]
Data provided by 24 states reported that solid waste from construction and demolition (C&D) accounts for 23% of total waste in the U.S. [5] This is almost a quarter of the total solid waste produced by the United States. During construction a lot of this waste spends in a landfill leaching toxic chemicals into the surrounding environment.
As a comparison, plastic road claims to dispose 8–10 kg (or 4-6%) of selected and washed plastic waste in the road surface per tons of asphalt, [4] while waste light concrete can dispose around 800 kg / tons of road base concrete with only low energy consumption shredding and mixing at room temperature. However, these two technologies can be ...
It was announced in February 2024 that 12 locations in Melbourne would offer drop off bins for scrunchable food soft plastic that could be recycled through a newly operated facility. [75] The new program aims at reusing the soft plastic into shopping trolleys and baskets, replace aggregate in concrete or become an additive for asphalt road. [76]
Computer monitors are typically packed into low stacks on wooden pallets for recycling and then shrink-wrapped. [1]Electronic waste recycling, electronics recycling, or e-waste recycling is the disassembly and separation of components and raw materials of waste electronics; when referring to specific types of e-waste, the terms like computer recycling or mobile phone recycling may be used.
