Back to our experiemental repurposed office shredder this week with some ‘adaptation’ of the casing to widen the access to cutting blades.  Not surprisingly attention swiftly turned to designs for the safety hopper! The hopper needs to tick several boxes.  It needs to be able to accept a number of pieces of plastic waste whilst preventing access to the cutter blades and ideally, incorporate the existing sensor so that the cutter blades rotate only when the hopper door is shut.   As the shredder blades are smaller than in the Precious…

Back into the swing of things after the Christmas break and a couple of new members joined the group.  As well as bringing our new faces up to speed, we looked at the parts required to build the plastic extrusion machine.  These will be added to our ‘shopping list’ and will be available on the website shortly. We’ve set up a WhatsApp group to make it easier for people interested in our WMS Precious Plastic group to communicate.  If you are interested you can join the group via this link:…

The component parts of the first machine fall into three main groups; the frame and structure, the motor and electrics and the cutting assembly.  The group are confident of sourcing the rest of the structural…
