The separated waste collection bins in the street indeed get collected in one single bin on a collection vehicle.

The old one even had one entry for batteries; since there was nothing behind it to collect things thrown through there they just fell on the ground.
Clear example of the conflict between idea and practice.

@Andrew.
No idea what type of technology they use but you can recognise them on the chimney and cooling towers (Painted in happy floral designs).
The Wuhua one is in the far northwest of the city near the motorway junction of the third ring road and the motorway to Fuming.
The Xishan one is behind Xishan Mountain and nearer to Haikou then Kunming.
Wuhua N25-06-59 E102-39-31
Xishan N24-50-56 E102-32-25

Indeed en route ;-)

Note you are using the word "approach" here wrongly. The approach is when the plane is about to land, this involves flying at lower altitutes which are more prone to turbulence. At approach one always has to wear seatbelds (Tables volded up and seats in upright position and window shutter open).
The right word is "an route" to Kunming.

Indeed more fenced off area but within days they have removed some poles and they are parking cars on the pavement again.
