The Problem: Plastic Waste

It begins by identifying and collecting discarded plastic from local landfills and communities that would otherwise pollute our environment.

The Solution: Proprietary Machinery

We build and operate specialized machinery designed specifically for small-scale, high-impact plastic recycling.

At Work: Sorting, Shredding & Extrusion

Trainees learn the hands-on process of cleaning, sorting by polymer type, shredding into flakes, and melting the plastic safely.

The Result: Sustainable Goods

The upcycled plastic is molded into beautiful, functional, and sellable items, creating a true circular economy.

Not all plastics are created equal. Before upcycling, our team is rigorously trained to identify, sort, and understand the precise materials we are working with to ensure structural quality and operational safety.

Standard Categorization

We expertly categorize plastics using standard recycling codes. We separate waste into highly specific bins, focusing heavily on processing PET, HDPE, PVC, LDPE, PP, and PS. Proper segregation prevents chemical mixing during the melting process.

Water Density Sorting

To ensure pure plastic batches, we employ advanced sorting techniques like the float-test. By utilizing water density, we can submerge shredded mixed plastics to separate them: HDPE, LDPE, and PP will float, while PET, PVC, and PS will sink.

Physical Properties

We map the exact physical characteristics of each polymer. Understanding optimal melting temperatures—which range from 130°C for HDPE to over 260°C for PET—is crucial for safely configuring our extrusion and injection machines.

Visual Identification

When recycling codes are missing from collected waste, our team uses visual and tactile property tests. We assess clarity, flexibility, and snap-behavior to accurately identify unlabeled plastic polymers safely.

At SheWorks, we don't just use machines—we engineer them. Utilizing advanced CAD files, precision laser-cut blueprints, and strict Bills of Materials, our team constructs specialized, industrial-grade recycling machinery. Here is a look at the technology powering our workspace.

• Shredder
• Injection
• Compression
• Extrusion
• Industrial Units

The Basic Shredder

The core of our plastic workspace. This machine uses a powerful motor to grind collected plastic waste into uniform, workable flakes, preparing it for the melting process.

• Precision Engineering: Built using laser-cut steel parts for the shredding axes and hex blades.
• Custom Framework: Welded, heavy-duty framework designed from exact technical blueprints.
• Safe Electronics: Assembled with a dedicated, secure electronics box for safe operation.

The Injection Machine

This machine heats the shredded plastic flakes and plunges the melted polymer into custom molds to create detailed, solid objects.

• Heated Barrel: Engineered with insulated heating bands to reach optimal melting temperatures safely.
• Plunger System: Designed with a sturdy lever mechanism for high-pressure manual injection.
• Hopper Assembly: Custom-built hopper to ensure a smooth, continuous feed of plastic flakes.

The Compression Machine

Utilizing an electric oven and a heavy-duty car jack system, this machine presses melted plastic into large, solid shapes like bowls, plates, and building materials.

• Reinforced Frame: Built to withstand immense vertical pressure from the compression jack.
• Oven Integration: Carefully calibrated heating elements to bake the plastic evenly without burning.

The Extrusion Machine

This machine melts plastic and continuously pushes it through a nozzle. It is highly versatile, used for making continuous beams, bricks, or wrapping plastic around molds.

• Extrusion Screw: Specially machined screw to continuously drive and melt the plastic forward.
• Custom Nozzles: Interchangeable nozzles designed to create different shapes and thicknesses.

Industrial Grade Machinery

For high-volume production, we scale up our engineering. Our industrial units are built for maximum output and continuous operation.

Shredder Pro

A massive upgrade in torque and blade size, capable of shredding thicker, harder plastics at a much faster rate.

Extrusion Pro

Designed for continuous, industrial-level output, perfect for creating large architectural beams and structural materials.

Sheetpress

An advanced heated press used to melt flakes into large, flat plastic boards for furniture building and construction.

A successful upcycling operation begins with a steady, high-quality stream of plastic waste. At SheWorks, we don't just wait for plastic to arrive; we actively engage our local community and businesses to build a reliable, educational collection network.

Business & Community Outreach

We actively pitch to local enterprises using tailored corporate presentations. By partnering with SMEs and corporations, we intercept bulk plastic waste directly from the source before it ever reaches a landfill.

To encourage household recycling, we run local awareness campaigns. Using focused public messaging, we educate the community on the environmental and economic value of segregating their daily plastic waste.

Workspace Sorting Hubs

Quality control begins at the collection point. We utilize clear instructional materials to ensure all donated plastic is thoroughly washed, dried, and stripped of non-plastic labels or caps before entering our facility.

Once the plastic arrives at our facility, it is immediately categorized. We maintain clearly labeled, heavy-duty collection bins to keep polymer streams 100% pure for safe and effective machine extrusion.

Turning shredded plastic into valuable products requires precision, organization, and a commitment to circularity. We utilize standardized visual guides, labels, and stamps to ensure our workspace operates smoothly and our products remain recyclable.

Standardized Sorting Labels

Organization is critical in a plastic workspace. We use prominent, diamond-shaped sorting labels on all transparent storage bins. This prevents cross-contamination and allows trainees to instantly identify pure polymer streams (e.g., PET, HDPE, PS) before melting.

Thermal Processing Guides

To guarantee safety and product quality, large-format "Melting Temperatures" charts are displayed at every machine station. These visual prints provide operators with the exact heating ranges required for each specific plastic type, preventing burning and toxic fumes.

Recycling Code Stamps

True circularity means our creations can be recycled again. Every product we mold is imprinted with its corresponding polymer code (1-6) or a "MIX" stamp using precision-milled logo stamps. This guarantees that at the end of the product's lifespan, it can be easily identified and re-entered into the recycling stream.

Transitioning from a workspace to a sustainable enterprise requires careful planning. We provide comprehensive business tools and examples to help trainees model, calculate, and launch their own upcycling operations.

Action Plans & Examples

Using visual A0 Action Plan boards, teams can map out their daily operations, identify key resources, coordinate with collaborators, and pinpoint target groups in a highly collaborative format.

We offer pre-configured business models tailored to specific operational focuses, providing blueprint examples for Extrusion, Injection, Sheetpress, Shredder, and full Machine Shop setups.

Designing a functional upcycling facility requires careful planning of workflow, safety routing, and storage. We have standardized our workspace layouts into six specialized zones, providing all the necessary architectural tools to recreate them efficiently.

Our commitment to sustainability extends beyond traditional plastics. Through our Beyond Plastic research division, we develop and test organic, biodegradable alternatives. By utilizing organic waste like coffee grounds, citrus peels, potato peels, and fallen leaves, we are molding the future of zero-waste products.

The Bio Press

We engineered the Bio Press, a specialized machine designed specifically for molding delicate bioplastic mixtures. Built from custom blueprints and a strict Bill of Materials, it applies precise pressure to organic composites to create beautiful, sustainable goods.

Material Book & Recipes

Our research is meticulously documented in our Material Book. It contains detailed recipes and processing guidelines for transforming everyday organic waste into durable, moldable materials, drastically reducing our reliance on synthetic polymers.

Custom Moulds & Tooling

To support the Bio Press, we designed custom CAD models and blueprints for organic bowls, cups, and flat sheets. We also developed specialized machine add-ons, like rail guides, to ensure consistent and high-quality production of our organic wares.

Our shared identity is crucial for building a recognizable, global circular economy. The Universe module provides the comprehensive branding assets used to unify our decentralized network of recyclers and makers.
