We want to engage our audience to pay atention to their plastic use. That is why we built machines to show a small scale recycling process. We will share all our information, costs, possible suppliers, bill of materials and hope this will encourage people to get started in their local community.

Shredder

The Shredder

Our shredder converts plastic waste into small flakes which we can use in our other machines. The motion is delivered by a three phase 220V 2.2kw engine with reductor to generate enough strenth to cut plastic bottles. We included a safety valve and see trough hopper. The shedding unit consits of lasercut inox parts. All parts are mounted on a steel base and can be placed on any surface.

The Injector

Injector

The injector uses manual force to inject a shape with melted plastic. A steel pipe is heated to the plastic melting temerature. Plastic flakes are added an pressed into a mould by pulling a lever. This machine is suited for volumes up to 1/4 liter and can be mounted on a wall or in a steel frame.

The Shredder


Our shredder converts plastic waste into small flakes which we can use in our other machines.It consist out of two major components: an engine and a shredder box. The motion is delivered by a three phase 220V 2.2kw engine with reductor to generate enough strenth to cut plastic bottles. This engine is connected via a safety switch to ensure user safety. The shedding unit consits of lasercut inox parts where individual knives rotate at a constant speed. Direction of rotation can be inverted to reduce the risk of jamming. The shredded plastic falls onto a mesh with holes (size 5-10mm). When te flakes are small enough they will fall trough, if not they are driven upwards by the rotating knives to be shredder a second time. We included a safety valve and see trough hopper so you can safely monitor the shreddong process. All parts are mounted on a dubble steel base with option to collect the plastic flakes in a simple tray. The frame can be placed on any surface.

    If you want to get started we recommend visiting a local machine builder or recycling project. This will give a more realistic view of the proces. You can locate builders via this Precious Plastic Map .

    We can provide a detailed bill of materials including prices and suppliers. We will ad a "step by step"(Work in progress) instruction guide. You will need acces to some specialised machines or buy all parts custom made.

  • Adaptations From Precious Plastic
    Aanpassingen aan Precious Plastic

    For those who already know the Precious Plastic project we decided to focus on the adaptations we made to the original design and why. Our main argument is based on our goal: We want to help local schools/ communities and businesses to get started. Working in an educative environment makes safety a top priority. We hope explaining our choises will simplify your own machine development.

    THE ENGINE

    Unlike Precious Plastic we chose to work with new CE certified engines. We added an emergency stop and a direction reversal function. To gegenerate enough force we opted for a 2.2kW tree phase engine. In our first design we used a 0.75kW monophased engine and it did not provide enough strength to shred full PET bottles so we needed an upgrade. To control both speed and to connect the tree phased engine to a standard power supply we added a frequency control. This does make for a higher cost but ensures both safety and reliability.

    THE SHREDDER UNIT

    We are still working on an update. More information will follow.

    THE HOPPER

    We chose to use a see though hopper to alow a safe view into the shredder unit. Polycarbonate sheets seemd to be the best choise due to the strength, toughness and heat resistance.

    THE HOPPER SAFETY VALVE

    We installed an extra safety valve just above the shredder unit so it can be closed easily when required. This laser cut inox part can be found in the download.

    THE BASE

    Because we want to be a mobile installation we opted to make a smaller frame and use fight cases both as a container and as a steady base. If it is available we can also use work benches, racks,... We did keep enough height in the frame to collect the plastic flakes and to secure the needed electronics.

The Injector


The injector uses manual force to inject a shape with melted plastic. A steel pipe is heated to the plastic melting temerature. Plastic flakes are added an pressed into a mould by pulling a lever that pushes down on the melded plastic. This machine is suited for volumes up to 1/4 liter and can be mounted on a wall or in a steel frame. To ensure user safety we mounted the heated elements in the center of the frame so there is less risk of contact with these high temperatures. The moulds are fitted via our custom made coupling system so we can easily acces the pipe for cleaning. This is an advantage when working with different plasic types.

Our main argument is based on our goal: We want to help local schools/ communities and businesses to get started. Working in an educative environment makes safety a top priority. We hope explaining our choises will simplify your own machine development.

    THE FRAME

    In order to save materials and space we changed the frame. An extra feature is that the heated parts of the injection machine are surrounded by the frame so it is safer to use. By sliding the foot (3x3cm square bar ) into the frame that has a 4x4 square bar and locking it into place the machine is secured.

    THE MOULD COUPLING

    Because we use small moulds for this machine we need to change them often while the injection machine is heated and the plastic melted. To aviod a mess with dripping plastic we added a sliding valve so we can disconnect the moulds propperly. We also made a joint using a dubble M-M nipple (metric 16) to srew and unscrew the moulds propperly. The coupling can be dismounted witch allows the heated tube to be cleaned. This allows us to melt different types of plastic in the same machine.

    THE HINGE

    We used a 4x4cm square bar in stead of 2 flat strips as a part of the leaver system to stabilize the pushing rod.

    THE HOPPER

    Our hopper is made out of 2 parts: the original hopper sides are cut out of a 1mm metal plate as one piece and bent into their final shape. To ensure a tight bottom fit to the barrel we use a metal plate with a 30mm diameter hole that slides over the barrel.

    THE HOPPER SAFETY VALVE

    We installed an extra safety valve just above the hopper unit so it can be closed easily when required. This prevents hot wax from escaping when the plastic is heated. It is also a pre adaptation to fit an air suction system to eliminate fumes formed during the heating proces.

    THE HEATING CONFIGURATION

    We deiced to change the 1 vs 3 heated elements configuration to a 2 vs 2 setup to get a better influece on melting temperatures.

    ISOLATION

    Because the steel pipe is heated to high temperatures (150-200°C) and we want to limit heat distribution through the frame we isolated the heated parts.

The Extrudor


The extrudor is an engine driven machine that produces a continues stream of plastic. This allows us to make plastic wires, 3D Filament and larger plastic bars and beams. The three phase 0.55kW engine drives a screw trough a heated metal pipe into a mould. The conical shape of the screw compresses the plastic so a compact mass is ejected. The machine frame can be mounted on our multipurpose frame or be placed on a flight case/table/... Moulds are fitted via our custom made coupling system so we can easily acces the pipe for cleaning. This is an advantage when working with different plasic types.

    THE SCREW COUPLING

    In stead of using a fixed coupling and a bearing to correct any angles we chose to work with a more flexible coupling to the engine. This allows minor movement of the shrew and it will be able to self center in the heated tube.

    THE MOULD COUPLING

    We chose to use the same system as in the Injector and added a plate with multiple holes we can slide in front of the heated tube. This way we can easily determine the output diameter of the extrusion machine without changing moulds.
