Substrate recycling innovations from print provider

We tend to expect the makers of substrates to be the ones who come up with affordable and recyclable materials, but Australia’s Cactus Imaging is putting those manufacturers to shame. Cactus Imaging is Australia’s market leader for large format digital print, with extensive international and domestic client bases. It has worked with a major customer to develop a recyclable billboard material that can replace PVC which is more commonly used in Australia.

Plastic packaging and recycling too simple a conversation

The enthusiasm for plastics reuse and recycling initiatives is a step in the right direction, but it overlooks the role of consumers. For most people understanding what can and cannot be recycled is difficult, so perhaps the graphics industry can help. Perhaps plastic materials that can be composted should be marked as such, and brand owners could consider expanding efforts to aid guidance.

Plastic recycling

Packaging printed onLow Density Polyethylene (LDPE) is changing. LDPE is the cheapest and most commonly used recyclable plastic but it takes hundreds of years to biodegrade. This is in part why various packaging print buyers are moving to alternatives and a key candidate is plastics made from potato starch instead of polythene. Oxy-biodegradeable polymers cost 20% more than LDPEs but they can be composted, which is the good news. But they pose a problem in the recycling chain because they must be processed for composting which is unlikely to happen. This is not so good. Should consumers be offered composting options or should they opt for LDPE packaging which can be recycled or incinerated to generate energy?
