Earth-to-go Earth Bowl EB-32
Lower concern. Compostable fiber bowls typically avoid PFAS.
Earth-to-go bowls are molded from plant fiber and compostable. No known PFAS-containing coatings; fiber packaging presents lower PFAS risk than plastic or treated materials.

What’s concerning
Category baseline
food packaging is a category where PFAS exposure is more common.
Formaldehyde / VOCs
Molded fiber bowls may be bonded with formaldehyde-based adhesives or starch binders during manufacture. Earthwise has not published test data on formaldehyde emissions. Contact with warm foods could theoretically increase release, though risk is considered low for food-contact temperatures below 60°C.
Source: ATSDR ↗Bacterial or mold growth if moisture-trapped
Porous fiber pulp can absorb water and harbor microbial growth if not dried quickly or stored in humid conditions. Visible mold or water staining indicates the material barrier has been compromised and the bowl should be discarded.
Heat-induced structural failure and food contact breakdown
Molded fiber is not designed for hot liquids or high temperatures. Boiling water, microwaving, or oven use can soften, warp, or partially dissolve the material, potentially exposing food to degradation products and loss of barrier function.
What’s reassuring
Safe base material
Made from a material with no inherent PFAS use (ceramic, mineral, or natural fiber).
BPA & bisphenols
Molded fiber pulp does not contain or leach BPA, BPS, or phthalates. This material class avoids the plastic polymer chemistry that produces these endocrine disruptors.
Source: FDA ↗Fiber shedding or microfiber migration into food
Intact, undamaged molded fiber bowls do not shed fibers into food under normal use. Deteriorated or heavily abraded bowls may shed microscopic particles; replacement is recommended at that point.
The full breakdown
What it's made of and why it matters
The Earth Bowl EB-32 is molded from plant-based fiber pulp, typically derived from recycled paper, sugarcane bagasse, or wood cellulose. This material avoids the leaching concerns tied to plastics (BPA, BPS, phthalates) and the coating degradation issues of ceramic or coated cookware. Molded fiber does not require synthetic binders or coatings in most formulations, reducing chemical exposure pathways during food contact. The material is designed to be compostable, meaning it breaks down in industrial or home composting systems without persistent residue.
The brand's record and disclosure
Earthwise has positioned itself in the eco-conscious food-service and takeout market but has published no detailed material safety data sheet or third-party certification visible in public records for the EB-32 line. The brand's PFAS stance is not transparently communicated, though the material class (molded fiber) inherently avoids PFAS use in most production. No recalls or safety controversies are documented for this specific product or brand in FDA or CPSC databases.
How it compares in its category
Molded fiber bowls represent a safer alternative to plastic food containers (which carry BPA/BPS and phthalate leaching risk) and single-use polystyrene foam (which can degrade and shed microplastics). Compared to ceramic or glazed stoneware bowls, fiber pulp eliminates risks from lead or cadmium in glazes. The trade-off is durability and heat resistance: molded fiber is not microwave or boiling-water safe, whereas ceramics and some plastics tolerate higher temperatures.
If you buy it
Use the bowl for room-temperature or warm (not hot) foods and beverages. Do not microwave, pour boiling water into it, or place it in a conventional oven. Store dry and away from high humidity to prevent mold growth or structural degradation. Discard if the bowl shows visible cracks, water absorption spots, or mold; these indicate breakdown of the fiber matrix and loss of food-contact integrity. Compost at end of life in industrial or certified home systems.
