Algae-Based Materials
The ocean grows furniture — bioplastic, fabric, and paint from algae
5 IMAGES — CLICK TO EXPAND
Algae-Based Materials are bioplastics, pigments, fabrics, and foams derived from micro- and macroalgae. Algae: Earth's fastest-growing organism (10× faster than land plants). Requires: no fresh water, no farmland, no fertilizers. Absorbs CO₂: 2× more than trees (per unit mass). For furniture: bioplastic (panels, parts), dyes (pigments), upholstery (algae fiber), packaging (alginate film).
TECHNICAL PASSPORT
Reception Space tracks algae materials as 'material of 2030': currently niche (art objects, prototypes, packaging). By 2030: algae bioplastic = mainstream (replacing petrochemicals). Leaders: Algaeing (Israel — pigments/textiles), Algiknit (USA — yarn), Notpla (UK — packaging), Bloom (algae foam for footwear). 2026 trend: living color (live algae as interior pigment).
Varieties & Types
Algae Bioplastic
$$$$Bioplastic from microalgae
Microalgae (Chlorella, Spirulina) → biomass → extrusion/pressing = bioplastic. Properties: like PLA (biodegradable). For: panels, furniture parts, handles, packaging. Color: natural green (or refined: beige). Brands: Algix, Solaplast.
Algae Foam (Bloom)
$$$Algae foam — EVA replacement
Algae biomass + EVA → foam (Bloom). Replaces: petrochemical EVA foam. For: shoe soles, furniture fills, packaging. Brands: Bloom (Algix) — for Adidas, Vivobarefoot. 15–60% algae content.
Algae Fiber (Algiknit)
$$$$$Algae yarn — for upholstery
Alginate (from brown algae: kelp) → yarn → fabric. Biodegradable. Tactile: like silk/linen. For: furniture upholstery, curtains, decorative textiles. Brands: Algiknit, Algaeing. Experimental (2026).
Algae Pigments (Living Color)
$$$$Pigments from microalgae — living dyes
Microalgae = natural pigments: green (chlorophyll), blue (phycocyanin), red (astaxanthin), yellow (carotenoids). For: furniture paint, textile dyes, bio-inks. Brands: Algaeing (Israel), Living Ink. No petrochemicals.

Expert Reviews
Average Rating · 5 expert reviews
«Algae bioplastic: 20+ objects (lamps, vases, panels). Material: Chlorella biomass + PLA (30/70). Extrusion: 3D printing (FDM). Color: natural green (beautiful!). Texture: matte, organic. Minus: brittle (like PLA). For art market: wow (each object = 'grew in the ocean'). Price: 3× vs PLA.»
«Bloom foam: main B2B product. Adidas (Ultra Boost Parley): 1M+ pairs. For furniture: starting (cushion fills, seats). Tactile: = EVA (client can't tell). Story: 'each cushion = cleaning a lake of algae.' For HoReCa: eco-statement. Price: +30% vs EVA. Trend: 2028 = 50% cushions from Bloom (forecast).»
«Algaeing (Tel-Aviv): natural pigments (phycocyanin → blue, chlorophyll → green). For: fabric dyeing (furniture upholstery, curtains). Result: soft, deep color (not synthetic). UV: fading in 3 years (solution: UV lacquer). For luxury: Hermès is testing (confidential). Story: 'color of the ocean for your armchair.'»
«Notpla packaging: testing for furniture delivery (replacing bubble wrap). Result: protection = bubble wrap. Decomposition: 4 weeks (vs 500 years). Minus: cost 5× (for now). For: eco-brands (premium). Clients: 'packaging from algae?!' → social media photo (free PR). By 2028: price = 2× (scale).»

Frequently Asked Questions
Yes (currently limited): 1) Bioplastic: handles, legs, panels (like PLA). 2) Foam (Bloom): seat/cushion filler. 3) Fabric: upholstery (alginate yarn). 4) Paint: pigments for furniture. 2030: full furniture parts from algae bioplastic.
Microalgae: single-celled (Chlorella, Spirulina) — green powder/paste. Macroalgae: kelp, Fucus — stalks. For materials: biomass is processed → clean product (bioplastic, yarn, pigment). Smell: after processing — minimal. Visually: not 'slime,' but engineered material.
Yes — Bloom (Algix): foam from algae biomass (15–60% algae + EVA). For: shoe soles (Adidas, Vivobarefoot), furniture fills, soft inserts. Tactile: like regular EVA foam. Plus: each pair of shoes = cleaning waterway of excess algae. For furniture: cushions, seats.
Petroleum plastic: from oil (non-renewable), decomposes 500 years, emits CO₂. Algae: from algae (renewable), compost 6–12 months, absorbs CO₂. Strength: algae weaker (2,900–7,250 vs 7,250–11,600 PSI). Price: 3–5× more expensive. By 2030: price parity (scale).
Yes — Algaeing (Israel): microalgae as pigment. Phycocyanin (blue), chlorophyll (green), astaxanthin (red). For: textile dyeing, furniture painting. No petrochemicals. Minus: UV stability lower (fading in 2–3 years). Solution: UV-protective coating. For luxury-eco: story = 'paint that grew in the ocean.'
Yes — Notpla (UK): packaging from alginate (brown algae). Dissolves in water in 4–6 weeks (or edible!). For: food packaging (Ooho: water capsules), furniture (bubble wrap replacement). Investment: $20M+. For furniture: eco-packaging (delivery → compost).
Yes — algae: don't need fresh water, land, fertilizer. Grow: in ocean (71% of Earth), bioreactors, wastewater (cleans it!). CO₂: absorb 2× more than trees. Problem: algae blooms (eutrophication) — Bloom uses THIS excess (= cleaning waterways + material). Win-win.
2026: niche (Bloom foam, pigments, art). 2028: bioplastic packaging (replacing single-use). 2030: furniture bioplastic (panels, parts). 2035: structural algae plastic. Investment: $2B+ (2024–2026). Trend: algae = 'oil of the future' (Exxon: $350M in algae-fuel research).
