Frequently Asked Questions

Who are Postwink's Customers?

Postwink is a B2B business – which means that we sell to other businesses. The majority of our customers are offices, corporates, universities and the commercial and industrial sector, comprising a variety of industries.  However, Postwink also widely supplies schools, waste management companies, municipalities, event organisers, residential complexes (Body Corporate Associations) as well as commercial property managers. If you are looking at improving your recycling at home, visit our separate online store, WAWO (pronouced “wah-woh”), which stands for WAste to WOrth.

Does Postwink come collect my Recyclable and/or Organic Waste?

Postwink sells a variety of standard and customised waste separation bins – including compost bins for food waste. We can also train staff on waste separation (T&Cs apply). However Postwink does NOT collect the recyclables for recycling or the organic waste for composting. That said, we are here to help! Visit our Recycling Collectors page for a list of companies collecting recyclables (or food waste for composting) nationwide, as well as a list of some drop-off areas.

How do I place an order?

Orders can be placed by completing a Contact us on this website (Contact) or by sending an e-mail to When placing an order, please remember to confirm your quantities and whether you know the type of recycling bins you would like.

Once an order has been placed, a proforma invoice will be issued to confirm the total cost of your order including delivery. A Tax invoice is issued on receipt of your 50% pre-payment.

What are the Terms of Payment?

In general, we require 50% payment to confirm your order, with the balance payable prior to your order being dispatched. Payments must be made via EFT. Cash deposits and Credit Card payments (via YOCO) are accepted but may attract additional bank charges. Note that Postwink does not accept cheques nor cash.

What are your lead times?

Apart for wheelie bins and cardboard bins, the majority of our products are made on order. Hence, expect a lead time varying from 2-4 weeks for your order. Although most of our recycling bins are made in South Africa, some recycling bins are imported and, depending on stock availability, those particular imported units may take up to 12 weeks.

Can I use my own colours for the various waste types, or must I adhere to the colours recommended by Postwink?

Although there are no international standards with regards to the colours used for recycling in South Africa, we do recommend sticking to the “most common” colours that are being used in the recycling industry , in order to maintain a degree of consistency and to not confuse the public, your staff or family. See our recommended pallet of colours below

What are the default colours per waste or which colours would Postwink recommend per waste-type?

There are currently no standard for colours used to differentiate the various recyclable waste, however we do believe in standardising these as much as we can in order to avoid confusion and educate more people about recycling. Unless requested otherwise, Postwink will use the following colours:

  • Blue for Paper
  • Green for Glass
  • Yellow for Plastics
  • Light grey/Silver for Cans, Tins and ferrous Metals (although, if no hazardous waste is collected, red is often used for metal)
  • Red (& sometimes Orange) for Hazardous Waste (including Medical Waste and oil cans)
  • Brown for Organic/Compostable Waste or Food/Wet waste
  • Green for Mixed Recycling or Recyclable dry waste
  • Black/Dark charcoal for non-recyclable, general (non-toxic) waste (i.e. the only waste which should be going to landfill)

A lot of the Postwink products use vinyls to label or brand the recycling bins. How do I clean vinyl?

In order to ensure the longest lifespan possible for your product, you need to clean the EcoCylinder lids and all vinyl labelling using only soap or mild detergent (like dishwashing liquid) in warm water, applied with a soft cloth or nylon sponge and then dry the vinyl with a soft cloth. Please do not use harsh detergents. This will shorten the lifespan of your vinyl, as well as being unkind to the environment. View the Bacterrorist enzyme cleaner as a tested alternative to clean vinyl.

How do I clean my Postwink Steel or Stainless steel recycling units?

The stainless steel recycling units, like the INOX or Sesame Sensor bins, should be cleaned using only soap or mild detergent (like dishwashing liquid) in warm water, applied with a soft cloth or nylon sponge. Please do not use harsh detergents for routine cleaning. Rinse and dry with a soft cloth and use a little olive oil to reduce the occurrence of streaks or finger prints.

Such cleaning will easily remove normal soiling. If your bin is more heavily soiled or stained, there are other methods. Please ask us for advice in this regard.

Remember however that prevention is better than cure, so try to maintain your recycling bin clean and dry at all times, to avoid a heavily soiled or stained bin.

What do you use to brand the outdoor Postwink igloo recycling bin?

For the igloo branding, we are using an Intercoat 1490 brand vinyl, which is a Polymeric PVC Glossy self-adhesive white vinyl. We are printing with solvent inks and apply a UVvarnish for additional UV protection. The vinyls are 80 microns and have an outdoor life expectancy of 2 years. For indoor and shaded areas (where no or little UV exposure happen), the life expectancy is approximately 5 to 7 years.

Most of your bins seem to have only one section for “plastics”. How do I know which plastics I can recycle?

In our opinion, it is very important for us, consumers, to be able to identify the various plastics we purchase – not in any detail, but just to ensure that when we purchase goods made from plastic (or packaged in plastic), we know whether our recycling collector or drop-off recycling centre accepts that particular plastic for recycling.

As consumers, we should try to avoid those plastics that are not widely recycled or recovered – especially when purchasing goods with a short lifespan.

For your convenience, Postwink has written various educational blogs and posts to attempt to educate the public.

There are only 7 numbers to remember! Then, please reconfirm with your recycling collector which ones they collect. Most will collect numbers 1,2 and 5 – but still check with them as they may also collect 6 (polystyrene) or some of the others as well.

Is Polystyrene recyclable?

Yes it is. View the Polystyrene Council website for information on the various products that are made from recycled polystyrene ( That said, not all collectors will collect as its demand in the industry varies. Hence, please check with your recycling collector before assuming they will collect it because it is recyclable.

What exactly is recyclable?

So much! From paper, tins, glass, most plastics (including those polystyrene cups), juice/milk cartons (called Tetrapak), aerosols, cartridges and e-waste (eg. computers, cellphones & appliances). For a more comprehensive list, read here: What to Recycle.

Also remember that food waste and garden waste (called Organic waste) is also “recycled” into compost – we call this Composting. Find out about composting your food waste and you will be diverting most of your waste from landfills.

Can I come Collect my order?

With some exceptions, you can collect your orders from our warehouse in Maitland. However, note that due to the bulky nature of our products, we recommend that we deliver them to your door instead.

Special arrangements can be made for Gauteng-based clients to collect from our Johannesburg depot, but again this is not recommended and we do prefer to deliver orders to ensure safe delivery.
