Reduce, Reuse, Recycle


Our college is working towards sustainable campus practices and solutions! Limiting waste and fostering reuse are at the core of sustainable practices. The following guidelines aim to inform the college community on good practices for sustainable waste management.

Here you can find some important waste prevention tips and best recycling practices to help you become a zero waste leader!

It all starts from this – the waste management hierarchy!

Everything begins by refusing the item offered and reducing the items we purchase, minimizing waste directly at the source, which is not creating it in the first place.

Just deciding not to spend $100 on stuff can save 100kg of greenhouse gas pollution! (1 million women)

Simple examples are refusing single-use straws, plastic bags, and choosing products with minimal packaging. You can also buy in bulk whenever possible using reusable containers!

Which brings us to Reuse & Repurpose. This has to do with reusing waste material and avoid disposing them. For instance, using glass food jars to store food items or even use them as beverage glasses. Or making notepads out of waste/scrap paper!

If you cannot avoid buying, reuse, or repurpose an item, the next best thing is to check if it is recyclable, follow the appropriate recycling guidelines/best practices at your country/area and put it in the recycling bin.

Unfortunately, recycling is the last solution which can divert some waste from the landfill/incinerator, because a lot of the items found out there are not recyclable to begin with while others can be recycled only a finite number of times. Take plastic for example – it almost always is downcycled (which means turning it into an lower quality product than the original one) and it can only be recycled once or twice.

The step you want to avoid at all costs is the final one; that of discarding waste the old-fashioned way, i.e. in the general waste bin. The best advice we can give you it to try to avoid this as much as possible!

Recycling @ ACG

On campus, you can follow the guidelines below for appropriate recycling and waste disposal:

For Paper & Cardboard

HOT Tips:


Recyclable Materials:

  • Magazines and newspapers
  • Old or destroyed books
  • Leaflets and junk mail
  • Paper catalogs and phone books
  • Envelopes
  • Computer/copy/fax paper
  • Cardboard boxes
  • Paper bags


  • NO dirty items and containers (e.g. pizza boxes)
  • Paper smaller than A4 size cannot be recycled due to size
  • NO paper tissues, napkins, kitchen and toilet paper
  • Do not crinkle the paper before throwing into the bins
  • Unfold cardboard boxes to minimize their volume before throwing into the bin
  • Shredded paper (from the shredder) cannot be recycled on its own. Place in a small cardboard box
  • Some on campus offices have an extra cardboard bin for recycling paper and cardboard boxes. Use the same instructions as for the Yellow Bin!

For Mixed Recyclables (plastic, aluminum, glass)

HOT Tips:


Recyclable materials:

  • Plastic packaging such as water and beverage bottles, oil bottles, detergent and other cleaning products, yoghurt, butter, toothpaste, shampoo and shower gel bottles, plastic wrap, bags, etc.
  • Glass packaging such as water and beverage bottles (milk, juices, and sodas), wines and other alcoholic beverages, food jars, etc.
  • Tin and tinplate packaging such as beers and soda cans, oil, coffee, condensed milk, tuna, tomato paste, legumes and beans, animal food, etc.


  • Empty all containers from residual food or liquids and rinse them before placing them into the bin
  • NO shattered glass in the blue bin
  • Small pieces of packaging are non-recyclable due to size
  • NO single use plastic utensils and drinking straws
  • NO biodegradable and/or photodegradable plastic bags
  • Always throw the materials in lose form and not in tied bags!
  • Plastic caps (e.g. from water bottles) go to the separate cylindrical bin to be recycled for a good cause!

For Residual Waste (aka anything that is non-recyclable)


  • Paper tissues, napkins, kitchen & toilet paper
  • Food waste/scraps (unless a composting/organic bacterial bin is available)
  • Dirty containers and items
  • Single-use plastics that cannot be recycled (straws, utensils, etc.)
  • Candy wrappers and chips packaging
  • Shattered glass
  • All foam containers
  • Office material such as plastic pens and small sticky-notes

Batteries, lamps, and ink cartridges.

Batteries are collected separately for recycling, as they are highly toxic and increase the pollution potential of discards. Batteries recycling points are located at the DC building at 400 level, the CN building 3rd floor, and the PC building, outside the Principal’s Office.

Used fluorescent lamps and bulbs are collected separately in the respective recycling point located at the DC building Main Corridor (opposite the SSC) and at the PC building Patio.

First, recycle the plastic wrap the ink cartridges come in when opening and then check with the IRM Department if they are refillable/recyclable. Ink cartridges should never end of up in the landfill.

Our campus will become greener if you make waste reduction and recycling part of your life.
