Dunkin is testing biodegradable straws made from PLA (polylactic acid), paper, and hybrid materials at select U.S. stores. This Dunkin biodegradable straws test evaluates durability, compostability, and customer satisfaction as part of the chain’s shift away from single-use plastic. The trial aims to identify a scalable alternative that meets the demands of high-volume quick-service restaurants.
What Types of Biodegradable Straws Is Dunkin Testing?
Dunkin’s trial includes three main categories of fast-food straw alternatives 2025:
- PLA (polylactic acid) straws – Made from cornstarch, these are industrially compostable but require specific facilities.
- Paper straws – Widely used but criticized for soggy texture; Dunkin is testing reinforced paper versions.
- Hybrid straws – Combine paper and a thin PLA coating for improved moisture resistance.
Each type undergoes rigorous QSR straw material comparison for performance in iced coffee, cold brew, and soda. Early results suggest hybrid straws are gaining favor for their balance of durability and compostability.
Operational Challenges of Biodegradable Straws in Quick-Service Restaurants
Switching to eco-friendly straws introduces several operational hurdles. PLA straws can become brittle in cold drinks, while paper straws often disintegrate before the beverage is finished. These issues directly affect customer satisfaction and drive-thru speed.
Cost is another factor: biodegradable straws can be two to three times more expensive than conventional plastic. For a chain like Dunkin, which serves millions of customers daily, even a small increase in per-straw cost has significant financial impact. This Dunkin biodegradable straws test helps quantify these trade-offs.
How Dunkin’s Approach Compares to Starbucks and Tims China
Other global chains are pursuing different paths. Starbucks Japan launched the “Green Planet” straw made from a biodegradable biopolymer derived from plants, while Tims China introduced CO₂ straws that capture carbon during production. Dunkin’s multi-material trial contrasts with these single-solution strategies, reflecting a more cautious, data-driven approach to quick-service restaurant sustainability.
By testing multiple straw types simultaneously, Dunkin can gather granular data on material performance across its diverse menu. This biodegradable straw trials US approach may set a precedent for other QSRs evaluating their own transitions.
What This Means for the Fast-Food Industry’s Plastic Phase-Out
The Dunkin biodegradable straws test is part of a broader industry shift. Regulatory pressures in states like California and New York are accelerating the move away from single-use plastic. Meanwhile, consumer expectations for Dunkin’ Donuts eco-friendly straws are rising. Dunkin’s findings will influence not only its own supply chain but also provide a blueprint for competitors.

FAQ
Q: When will Dunkin announce the results of its biodegradable straw test?
A: Dunkin has not released a specific timeline, but internal evaluations are expected to conclude by late 2026. A wider rollout may follow depending on customer feedback and operational feasibility.
Q: Are Dunkin’s test straws truly compostable?
A: PLA straws are industrially compostable but require facilities that accept them. Paper straws are home-compostable but degrade more slowly. Hybrid straws vary; check local composting guidelines.
Q: How are customers reacting to the new straws?
A: Early feedback indicates mixed opinions. Some appreciate the eco-friendly initiative, while others report straws becoming soggy or feeling brittle. Dunkin is using this feedback to refine material choices.
Dunkin’s careful testing underscores the complexity of replacing plastic in fast food. By comparing multiple materials, the chain is setting a benchmark for practical sustainability.
