Thanks for highlighting this news Jonathan. UBQ has been listed on Ubuntoo for quite a while. It seems to use a combination of pyrolysis with an extrusion process.

 Seems quite promising. I hope other members can shed more light on this.

Hi @zerosolidwaste.
It’s a sort of mechanical sorting with oscillating paddles. The agitation of the paddles has a different effect on the mingled waste stream causing a separation of rigid items off one end and flexible items off the other.
Stadler for example has this system: https://ubuntoo.com/solutions/stadler-f4999a47-6a98-4a8c-8507-eac287c41fd2

What information is out there about plastics being used as building materials? For instance, since plastic is so waterproof, would using recycled plastics as roofing be an option economically? What other recycled... Show More

Logan, I strongly believe that construction is one of the very few material industries that have the capacity to absorb the massive quantities of plastic and other waste that we generate every day. Check out https://www.continuusmaterials.com/everboard  for an example of an existing product and its application in the industrial roofing that could help solve the plastic waste crisis.

With feedstock in mind, is there any research done about the reuse of plastics with regards to 3-D printed items? For example, does anyone have knowledge on whether 3-D printed items are able to be used as feedstock?

I would be interested to know this as well, whether the items produced by 3D printing could be re-chipped and used again. I wonder also about the recyclability of 3D printed materials in traditional collections, even if it were to be printed with the “stamp” of the resin type whether it could make it through MRF processing like we have in the United States.

What are some of the best ways to encourage people to simply care about the environment and thus making a shift toward sustainability? Education? Laws forcing people to recycle, etc?

Davis Christensen , I'd say that putting value into waste would be a great option. For an example if we tell a set of people to separate waste so that the Recycling is easy or Environment will be better, there won't be too many. But if I tell those people that I'll pay them cash or I'd reward them at the end of month or week, they'd happy to work for it. Everybody wants free things or rewards.


I hope this helps!!

With plastics under pressure, we have recently seen a shift back to aluminum. Coke’s Dasani is rolling out water in aluminum cans and bottles, and Ball is now offering disposable aluminum cups… Are these offers a... Show More

Based on a figure posted on the website (https://futurism.com/plastic-decomposition), it takes double, if not longer, for plastic to break down than aluminum. Also, aluminum is worth more. By switching to using more aluminum could reduce the amount of plastic in the environment and aid in more recycling being done. Although neither of these two are going to be 100% recycled or reused, it still is worth the opportunity or chance to reduce the damage to the environment.
