Landfills are the primary method of waste disposal in many parts of the world, including United States and Canada.Bioreactor landfills are expected to reduce the amount of and costs associated with management of leachate, to increase the rate of production of methane (natural gas) for commercial purposes and reduce the amount of land required for land-fills.
These larger vehicles will transport the waste to the end point of disposal in an incinerator, landfill, or hazardous waste facility, or for recycling. Transfer stations can be publicly or privately owned. They vary in size, from small regional sites managing less than 1000 tonnes/year to large sites managing over 200,000 tonne/year. [1]

Residual unusable materials prepared for their final safe treatment (e.g., incineration or gasification) and/or landfill; Further advantages: Small fraction of inert residual waste; Reduction of the waste volume to be deposited to at least a half (density > 1.3 t/m 3), thus the lifetime of the landfill is at least twice as long as usual
Once a landfill site is full, it is sealed off to prevent precipitation ingress and new leachate formation. However, liners must have a lifespan, be it several hundred years or more. Eventually, any landfill liner could leak, [7] so the ground around landfills must be tested for leachate to prevent pollutants from contaminating groundwater.
Landfill operators who also use their site for recycling, incineration or sorting waste can apply to have the relevant area designated a tax-free site. The tax is administered by HM Revenue & Customs (and is known as the landfill tax) and it has been estimated that the tax will raise approximately £500m a year for the exchequer.
