If I was to go around again,I would definitely be using the waste to make bitumen hotmix product with....this was the only viable solution apart from landfill dumping.....now landfill dumping is OK if you go about it right .....flat land,preferably swamp,no runoff,just standing water ,...then you need a big excavator ,and dig deep slit trenches,and dump the waste well below surface level .This isnt difficult,you just keep the trench moving ,never too much exposed...........Now ,comes the best part .....40 years later you sell the land for a million bucks.
