Assume 1000 kg sample of waste

Component	% by mass	Mass/1000Kg	Typical density,Kg/m3	Total mass
(1)	(2)	(3)	(4)	(5) (3/4)
Food waste	15	150	290	0.52
Paper	45	450	85	5.29
Cardboard	10	100	50	2
Plastics	10	100	65	1.54
Garden wastes	10	100	105	0.95
Wood	5	50	240	0.21
Tin cans	5	50	90	0.56
-	100%	-	-	11.07

Density$= 1000/11.07\\ =90.33 kg/m3$
