Full Circle
Full Circle defaults to natural materials for the parts that do the work: cellulose and loofah sponges stitched with cotton thread rather than glued, solid-copper scrubbers, bamboo brush handles. Plastic still appears in some brush bodies and replaceable components across the wider range, so it's not absolute, but for sponges and scrubbers the brand's picks are genuinely plastic-free and compostable or recyclable.
How clear are their specs?
Product pages name the fibers (loofah, cellulose, walnut, copper) and the cotton-thread construction; a few items are less specific about binders on scrub pads.
Products we recommend
Loofah Scrubber Sponge
An all-plant combo sponge - loofah scrub side, cellulose wipe side, cotton stitching - at a few dollars a pair. Gritty when dry, softer when wet, and compostable.
Lucky Scrubber Copper Scourer
A scrubber of solid copper mesh for the baked-on jobs no plant fiber can handle. Naturally antimicrobial, sheds no microplastics, and recyclable as scrap metal when it finally frays.
