What is green fuel? Give information about waste recycling.

(N/A) Fuel obtained from plastic waste has a high octane rating. It contains no lead and is known as "green fuel".
Due to recent developments in chemical and textile industries,clothes are now being made from recycled plastic waste.
Technology has been developed to produce electricity from garbage. $A$ pilot plant has been set up where,after removing ferrous metals,plastic,glass,paper,etc.,from garbage,the remaining waste is mixed with water. It is then cultured with bacterial species to produce methane,which is known as biogas.
Biogas is used to generate electricity,and the remaining solid residue is used as manure.
