Diapers are one of the worst offenders when looking at landfill problems as millions of diapers are thrown away daily. Modern day eco conscious parents are reverting back to cloth diapers but so few people see cloth 
diapers as feasible alternatives that the ones who do use the reusable nappies are not making a positive dent in the problem. Good news has surfaced, however, and it may be possible to use those discarded diapers as the raw material for fuel to power our cars.
One of the reasons diapers are a viable source of conversion to fuel is the fact that they are consistent in substance. Using random garbage generates serious problems as the manufactures do not know what contents are present in any bundle of garbage. Diapers, on the other hand, are made basically the same way and can be collected in segregated disposal bins to carry to the processing plant. This means that the resulting concoction is the same every time creating a stable and consistent mix. And while other materials are incinerated causing deadly or toxic emissions, the diapers will be broken down molecule by molecule in a process called “pyrolysis” preventing any dangerous emissions and creating an alternative car fuel.
Apparently this process is not a theory but reality in Quebec, Canada where a plant is being built by AMEC PLC, the international engineering and project management conglomerate for a client, whose identity has not yet been disclosed, to convert diapers into synthetic diesel fuel.
Diapers are easily obtained through the collection of both infant and adult diapers. A system is already in place which makes collecting the diapers, known as foodstock in the alternative fuel industry, that much more popular as a raw source to convert to biofuels.
