Open-Source Global Marketplace for 40,000 Recyclers

Open-Source Global Marketplace for 40,000 Recyclers

In 2013, Dave Hakkens, a young designer from the Netherlands, envisioned a grassroots solution to one of the world’s most pressing environmental problems—plastic waste. He launched bazar.preciousplastic.com, an open-source community-driven project with a mission to empower people globally to turn discarded plastic into valuable products like furniture, lighting, accessories, and art.

But as the movement grew, so did the need for a platform that could connect thousands of eco-conscious creators and DIY recyclers. Precious Plastic needed more than a website; it required a vendor-friendly, scalable marketplace that aligned with its values of accessibility, transparency, and environmental impact. That’s where we stepped in.

Together, we transformed their CS-Cart Multi-Vendor into a fully customized P2P marketplace, specifically designed to support individual creators and small-scale recycling entrepreneurs worldwide.

Challenges

Simplify vendor onboarding for users unfamiliar with eCommerce platforms
Replace complex shipping calculations with a simplified pricing model
Ensure straightforward and mandatory payment setup before product listings
Enable collaborative communication through real-time messaging
Offer seamless support for international buyers and sellers

Implementing the Project

Here's how we customized the marketplace to meet the client's business objectives.

Simplified Vendor Experience

The typical vendor on Precious Plastic isn’t a large company—it’s an individual, often new to eCommerce, looking to share sustainable products. We transformed the vendor dashboard into a one-page, Etsy-style interface that allows new users to list products quickly and intuitively. Everything they need to get started is available at a glance—no technical knowledge required.

The vendor is almost like a customer. The mission is to allow them to create and sell a product without friction.

Intuitive Shipping Model

The default shipping calculator from the CS-Cart platform was too complex for the platform’s global DIY users. We simplified it entirely—replacing carrier-specific pricing (e.g., DHL, USPS) with a flat-rate system based on domestic vs. international regions. Vendors now define two prices: one for local orders and one for international shipments.

To support further customization, we also introduced regional grouping with prioritization, allowing vendors to override shipping costs for specific countries within their region (e.g., Germany within Europe).

Stripe Connect: Payment Setup First

Previously, vendors could list products before connecting their payment accounts—leading to broken sales flows and confusion. We modified this journey by making Stripe Connect setup a prerequisite for adding products.

Empty product states now guide users to set up payments first

This ensures every seller is fully prepared to accept orders and eliminates failed transactions due to missing payment accounts.

Real-Time Messaging + File Sharing

We expanded the Real-Time Messenger by enabling users to attach images and PDFs—perfect for sharing product mockups, sketches, and material references. This is especially helpful in a DIY, creative community where collaboration is key.

Vendor Transparency

We made it easier for buyers to connect with the story behind the products by showing the vendor’s name and country on both category and search results pages. This builds trust and emphasizes the community-driven nature of the platform.

Customers won’t lose sight of the vendor—it’s always visible alongside the product.

Cloud Hosting for Global Stability

To ensure performance and scalability as the platform continued to grow, we recommended our partner Scalesta for cloud hosting tailored for high-traffic marketplaces. This eliminated concerns regarding server management, downtime, and system maintenance, allowing the Precious Plastic team to focus on community building and content creation.

Ongoing Support and Development

Since the initial launch, our partnership with Precious Plastic has continued to evolve. We provide ongoing support to refine platform features, improve performance, and address emerging needs from their growing network of over 40,000 plastic recyclers worldwide.

Results

Frictionless Vendor Onboarding. First-time sellers can now register, connect payments, and list products within minutes.

Simplified Shipping Management. Vendors no longer struggle with confusing logistics calculations.

Payment Reliability. Every seller is ready to accept payments before listing products, improving the buyer experience.

Enhanced Communication Tools. Real-time file sharing allows better collaboration and design sharing.

Stronger Community Trust. Clear vendor identification and international visibility support ethical shopping.

Today, the marketplace forms an important part of the client's expanding digital ecosystem, supporting international growth while providing a scalable foundation for future commerce initiatives.

Their ability to respond quickly and to develop very specific requirements impressed us.
