Every year, scenic areas hand out millions of single-use cups, bags, straws, and tableware — and most of it ends up as plastic waste. Replacing the material is only half the job. Unless the replacement is collected, composted, and returned to the soil, the loop never closes.
Greenstar’s low-carbon, zero-waste solution closes it in four steps, with one bin.
1. Replace
Single-use plastics are replaced with certified compostable alternatives: PLA cold-drink cups and lids, PLA-coated hot-drink cups and lids, compostable straws, compostable carry bags, and other compostable tableware and packaging, meeting ISO 17088 and ISO 14855-1.
2. Recover
Everything discarded on site can be composted — so there is only one compostable bin. One bin dramatically simplifies waste collection and transport.
3. Treat
Compostable products go to an aerobic composting facility, where they become humus.
4. Return
The compost goes back to the fields or gardens, improving soil quality — and the loop closes.
Where it works
Dining: cold-drink cups and lids, hot-drink cups and lids, straws, carry bags, tableware. Retail: shopping bags, packaging bags, beverage bottles. Lodging: guest-room disposables, carry bags. Shuttle transport: on-board drink cups, packaging. On-site events: food-service cups and tableware, packaging, promotional materials. The same four-step loop also applies to stadiums and events, and to restaurants.
Measurable, not just visible
Every replacement product carries its own numbers — how much carbon it avoids, how much plastic waste it prevents. For example, every tonne of our compostable garbage bags replacing conventional plastic bags avoids 1 tonne of plastic waste and cuts a net 2.5 tonnes of CO₂e.
The bins carry the same numbers, matched to what they collect. Electronic display boards around the site show three running totals — carbon reduced, plastic reduced, and trees saved — calculated from collection and composting records.
Certifications
Our compostable products are certified to ASTM D6400, EN 13432, and GB/T 19277 (industrial composting).
