How much we saved through recycling of solid waste?
The University saved over 374 tonnes of solid wastes through recycling and turned 7 tonnes of glass bottles into bricks in 2012.
We promoted the reuse of used furniture and salvaged building materials and fixtures, recycling of recyclables (including food waste) and repairing of defective engineering parts / items to lessen the burden of our landfills and help save valuable resources of the University. The following are some examples:
Salvaged Building Materials and Fixtures
Recovery of Solid Wastes
CityU recycles paper, aluminium cans, plastic bottles, printer cartridges, plastic bags, rechargeable batteries, CDs, foams, mercury-containing fluorescent tubes and lamps, food waste and glass bottles. Recycling was expanded to Run Run Shaw Creative Media Centre (CMC), Academic 2 (AC2) and Nam Shan Building (NSB).
To ensure the "Two-Bin” system –one for all recyclable materials and the other for "landfill" – will lead to substantial is followed. cleaners in CityU are required to separate recyclables from the waste produced in office areas to allow more recyclables to be recovered for recycling.
Recycling and Deferred Replacement of Lubrication Oil
Replacement of lubrication oil in chiller compressors is done subject to the analysis results of the condition of the oil and maintenance contractors are required to recycle the used lubrication oil. The approach of condition-based oil replacement avoids premature replacement that would otherwise generate wastages.
A number of pressure vessel diaphragms, ball valves, motor bearings, etc. have been repaired / reconditioned and put back into service, thus saving the material cost.
