Is Hardwood plastic?
The short answer
No plastic to shed. Wood was the comparison arm in the study that measured plastic cutting boards, and it is the reason that study reads the way it does — a wooden board generates wood particles.
Also called: wood cutting board, maple board, wooden utensils, wood vs plastic
How it behaves
The four conditions that decide whether a material is a problem in practice rather than in principle.
- Heat
- None
Does normal domestic heat degrade it?
- Abrasion
- None
Do scratching, cutting or flexing generate particles?
- Fatty food
- None
Does fat pull additives or particles out of it?
- Acidic food
- None
Do acidic contents attack the surface?
What Hardwood actually is
Solid hardwood — maple, beech, walnut, cherry — finished with food-grade mineral oil or beeswax. Knife marks close over rather than opening into a shedding surface, and a board can be sanded back to new. Its bacterial reputation is considerably better than folklore suggests.
Where you find it
Why Hardwood is not a microplastic source
Nothing polymer-related. Two things to watch that are not microplastics: bamboo and composite boards are frequently resin-laminated and are not the same material as solid hardwood, and a board finished with a glossy polyurethane seal has a plastic surface on it. Mineral oil and beeswax finishes have neither problem.
Graded B. The product category and packaging format have been measured, but this specific brand or SKU has not. We apply the category result and say so. This is the most common grade, and honestly so. How evidence grades work →
How to tell you're holding it
Visible continuous grain running through the edge, not just printed on the face
Solid boards are heavy; laminated ones show glue lines between strips
A matte, slightly absorbent surface means an oil finish rather than a plastic seal
This is what we recommend switching to
Hardwood is the alternative named on 4 other material pages — Nylon, Polyester, Polyurethane, Bamboo composite. There is no upgrade from here.

Not sure what yours is made of?
Most products never state the polymer, and a resin code on the base only tells you about the body — not the lid, the liner or the seal. Scan the item and the app identifies the materials in it, then scores them together.
Identify what mine is made ofSources
Yadav 2023 — Chopping on a plastic board generated an estimated 14.5–71.9 million polypropylene microplastics per person per year, and around 79.4 million from a polyethylene board.
Limitation: Controlled chopping by a set protocol, extrapolated to annual figures. Real kitchens vary enormously in board use, knife type and replacement frequency.

Bamboo composite
Depends entirely on the product, and the marketing will not tell you. Bamboo boards are strips glued with resin. "Bamboo fibre" tableware is usually bamboo powder bound in melamine resin — which is a plastic dish with bamboo in it.
Paper and paperboard
Uncoated paper sheds no polymer. The problem is that most paper that touches food is not uncoated — cups, cartons and many takeaway boxes carry a polyethylene or PLA lining you cannot see.
Cotton and linen
No. Cotton and linen are cellulose fibres — they shed fibres, and those fibres are not microplastics. Blends are the trap: a 60/40 cotton-polyester shirt sheds polyester.
Beeswax wrap
No polymer. A beeswax wrap is cotton impregnated with beeswax, tree resin and oil — the direct replacement for the one kitchen product with the highest food-contact surface area of all.
