More Information. This should be more than enough for you to build your own bicycle powered shredder : Bicycle plastic shredder could not use the supporting files tab, since our files exceeded the maximum file size amount.

Let us introduce ourselves, we are Sophie, Jamil and Emma. We do this with a budget friendly, innovative and sustainable alternative for recycling plastic waste. Zanzibar is known for its beautiful white beaches, clear turquoise blue waters and rich history. More than Unfortunately, tourism causes vast amounts of plastic waste on the island. This litter is poorly managed and large amounts end up in the ocean, which has drastic consequences for the environment and ecosystem of Zanzibar. They up-cycle the waste into beautiful locally produced, artisan crafted products and sell this across the globe.

Bike shredders, an essential category within the recycling equipment industry, cater to the specific need of pulverizing bicycles and similar materials into recyclable fragments. These robust machines are engineered to support environmental sustainability by transforming waste into valuable raw materials for new production cycles. The versatility of bike shredders like the haro shredder pro 24 and haro shredder 20 allows them to handle a variety of materials beyond just bicycles. From haro bmx shredder frames to plastic packaging, these machines are adept at reducing volume and preparing materials for recycling, serving both small-scale operations and larger industrial processes. A typical bike shredder is equipped with a powerful motor and cutting blades designed for efficiency and durability. The machinery is capable of breaking down not only metal frames but also plastic components into smaller pieces. Models vary from single shaft designs, ideal for materials that require high-pressure processing like the haro 18 shredder , to double shaft options suitable for larger volumes of less resistant materials. The construction of bike shredders involves heavy-duty materials that withstand the rigors of crushing and shredding. The internal mechanisms are crafted to ensure consistent output sizes, which is crucial for materials like the haro shredder frames, known for their robust build. Modern shredders, including the haro shredder pro 20 and haro shredder 24 , offer enhanced efficiency and reduced energy consumption.

The rest of it are just ready-to-use standard parts.

While electric motors have taken the drudgery out of many tasks, human power has its advantages. Designed primarily for educational purposes at venues where electricity can be difficult to source, but also useful for off-grid environments, this exercise bike-based shredder can take small pieces of plastic and shred them into tiny pieces suitable for use with any of the other machines in the Precious Plastics ecosystem like their injection molding machine. As with all [Precious Plastics] projects, the files are will be open source ; however, there is a six month exclusivity period for Patreon subscribers to help fund development efforts. The build is relatively simple: take an old exercise bike, remove the unnecessary bits, and run the chain up to drive a shredding mechanism mounted on the front of the bike. Maybe the next step is getting these in spin classes around the country so people can get their exercise and help recycle in their community at the same time!

Built or buy the shredder box Precious Plastics has very detailed plans on how to built a shredder box. On the Precious Plastics Bazar you can also buy one. Built the custom axle With this custom flywheel and axle, you can create forward momentum to shred the plastic. The flywheel will also provide a perfect base to connect the gears talked about in step 5. All the cutting files and the technical drawings can be found in the files in step 1.

In , the global plastic waste per annum was at about million tonnes. This trend of an increase in plastic waste seems like it has no intention of stopping, even more so during the ongoing pandemic where the use of disposable plastics is on the rise. At this point, we all already know the negative consequences that plastic pollution has on the environment and ourselves, making the need for more plastic recycling globally that much more imminent. However, in developing nations such as Kenya, this tends to be quite the challenge. Although larger cities such as Nairobi already have some plastic recycling companies, rural locations are in dire need of local recycling solutions, which is where my project comes in. My design challenge is to design and create a plastic shredder in need of minimal infrastructure although the recycling part becomes trickier in these rural locations. In short, there are already multiple plastic shredder designs and types out there.

Hi there! Haven't found the right supplier yet? That is why we care a lot about safety! Let's start shredding plastic! A large gear is attached to shredder box and a large crankset is attached to the custom flywheel. Choosing the Right Shredder Selecting the appropriate shredder, such as a haro 16 inch bike shredder, depends on the specific recycling requirements. So we decided to shred plastic with human power at high speed. Workshops with different kinds of people are our daily business. All the cutting files and the technical drawings can be found in the files in step 1. However, we are aware that these components are not available in every country in the world. This site uses Akismet to reduce spam. Furthermore a short introduction video and an assembling video is in the making to get a better understanding about the construction. That's important to clamp the rear-wheel right in place. Moreover it empowers women and youth with knowledge, a trait and fair wages, which is also very important, given that half of the population of Zanzibar lives below the poverty line. The wheel-mount is a lot of lathe work but not too complex!

More Information. Initially the number of shredder blades will need to be reduced down to around 9 from the original design so that the shredder is thin and light enough to be mounted on the back of a bicycle, however more can be incorporated if desired. The depth of the shredder housing will then need to be scaled down in co-ordination with the reduced number of blades.

There are different ways to build the axle. Very small holes will turn the plastic nearly into dust. Using high speed instead, we have the power of inertia Sell on Alibaba. The downside of the new version is the huge size and weight compared to the old one. Finally, we dismissed the pipe lock because of malfunctions. Made by. Donate Bring in your own project. We take a long steel bar 14mm in diameter. When the pilot bike-shredder is a success, CHAKO will easily be able to build more bike-shredders from our design. Comment Policy.
