A circular economy platform aiming to bring waste and by-products back into the economy with digital marketplace logic.

Problem

Most industrial waste is simply disposed of; recyclable materials exit the economy. Waste producers cannot find buyers, recycling companies search for raw material, and the market in between offers neither price transparency nor a working circular economy infrastructure.

Solution

GreenMarket was built as a B2B marketplace that digitizes the buying and selling of waste: supplier-buyer matching, price discovery through auction and fixed-price models, integrated logistics planning, and escrow-based secure payment. Every transaction becomes measurable through environmental impact and carbon savings reporting.

Circular economy marketplace — representative preview

One of the industrial economy’s most expensive habits is consuming resources in one direction only. A factory’s production offcuts, a construction site’s rubble, a hotel chain’s organic waste — most of it is destroyed at disposal facilities. Yet the same materials could be exactly the raw material another facility a few kilometers away is looking for. GreenMarket is a circular economy platform developed within Group Taiga to close that disconnect. The core thesis framed by Selman Yılmaz is simple: one company’s leftover is another company’s raw material; the only thing missing is the market infrastructure that brings the two sides together.

Problem

Turkey generates more than 32 million tons of municipal waste a year; the volume of industrial waste is far above that. Against this, the recycling rate stays in the 15–20 percent band. The problem is not a lack of will but a lack of infrastructure. The factory producing waste cannot find a buyer for its plastic or metal scrap. The recycling facility cannot find a reliable channel for a steady, quality supply of raw material. The market in between has no price transparency; transactions proceed scattered, unrecorded, and without scale. As the EU Green Deal, the carbon border adjustment mechanism (CBAM), and ESG investor expectations raise regulatory pressure every year, this structural gap is billed as both economic loss and a heavy carbon footprint.

Solution

GreenMarket was designed as a digital marketplace that makes the e-commerce of waste possible. On the selling side are factories, construction companies, hotels, retail chains, and municipalities; on the buying side, recycling facilities, raw material processors, energy producers, and upcycling ventures. Producers list their materials with quality, quantity, photos, and analysis reports; buyers reach what they need through location-based search and price comparison. Price discovery is supported by auction and fixed-price models alongside recurring supply agreements. On the logistics side, carrier matching, cost calculation, and tracking are built into the platform; payment is secured with escrow logic on Taiga Inc infrastructure.

System

The platform’s scope was set wide enough to reflect the circular economy’s true volume: plastic, metal, paper and cardboard, organic, construction, textile, and electronic waste categories all trade under one roof. The real differentiating layer is reporting. Every transaction produces direct input for the increasingly heavy regulatory and investor demands companies face:

  • Environmental impact reports and carbon savings calculation
  • Sustainability certification and ESG reporting support

This setup takes GreenMarket beyond a trading screen and makes it part of corporate sustainability operations. In the category opened by global examples such as Rubicon, Rheaply, and Cirplus, the platform positions itself with category depth specific to the Turkish market and local logistics integration.

There is no such thing as trash; there are resources in the wrong place. GreenMarket builds the bridge that carries those resources to the right place — the digital infrastructure of the circular economy.
