Cyprasein

Overview

Cyprasein is a 100% biodegradable bioplastic developed by ARBOK's Cyprus division that transforms dairy and winery by-products into a durable, flexible material for packaging, tableware, cutlery and industrial containers. It is positioned as a replacement for the outdated "Galalith" and covers applications from ultra-thin supermarket films to fruit and vegetable crates. The material decomposes in 1–2 years without a trace or toxic waste, so that organic products can be packaged in genuinely organic packaging with no sorting required at home or at work. Cyprasein is free of chemicals, purely natural and fully degradable.

Applications

Food packaging; children's toys (safe for mouthing); disposable tableware for cafes; agricultural product packaging and agricultural films that enrich soil; ultra-thin films for supermarkets; fruit and vegetable crates; industrial containers; bags and straws; trash bags; and any application where polymer films are used today. Target customers named: hotels, restaurants, supermarkets, delivery services, fast food, and any packaging for products with a 1–2-year shelf life. Suited to single-use items. Ideal for frozen food packaging at -20 °C, where PLA becomes brittle. Under development: water-resistant versions for medical packaging and heat-resistant versions up to 80 °C for hot beverages.

Operating Principle

Cyprasein is produced from two problematic waste streams: dairy residues and grape pomace. ARBOK's cold evaporation technology extracts casein — a structural protein recovered from dairy waste — which forms the backbone of the bioplastic. A separate proprietary process converts grape pomace and other fruit waste into an organic binding agent that cross-links with the casein, giving the finished material its flexibility, durability and strength while keeping the formulation entirely organic. No petrochemicals are used at any stage — only natural, waste-derived ingredients processed through energy-efficient methods. The material can be shaped into films, rigid parts, or scented products with organic additives such as lavender or citrus.

Stated limitations carried over from the source: limited water resistance under prolonged liquid contact — the stated mitigation is that the 2-year degradation timeline suits most products' shelf life, especially perishables, with a hydrophobic-coating version planned by 2026 for medical packaging. Grape pomace supply is subject to seasonal fluctuations — the stated mitigation is diversification into apple and citrus waste, available year-round, and a network of 50 collection points in the Mediterranean by 2027.

Architecture and Components

Casein extracted from dairy waste, forming the material's structural backbone. An organic binding component derived from processed grape pomace and other fruit waste, produced via a proprietary conversion process. ARBOK cold evaporation equipment for casein extraction. Dedicated processing equipment for converting grape pomace and fruit waste into the organic binding component. Optional organic additives for scented products (lavender, citrus). Containerized processing units for deployment, sized for co-location with dairy and winery waste sources.

Advantages

• 100% organic and independent of petrochemicals, unlike bio-PET which is only partially renewable.
• Degrades naturally in soil or water at ambient temperature, unlike PLA which requires industrial composting at 60 °C.
• Uses waste rather than crops, avoiding food-chain competition unlike starch-based plastics.
• PBAT requires petrochemicals and is 30% more expensive; Cyprasein uses waste, reducing costs.
• Production cost 3–5 times lower than PHA ($4–6/kg).
• Tensile strength ~30 MPa rivalling polyethylene, with flexibility permitting 10-micron films without quality loss.
• Retains performance at -20 °C where PLA becomes brittle.
• Safe for marine life if bags or straws end up in the ocean.
• Reduces landfill waste accumulation by 30–50% compared to petroleum-based alternatives (European Bioplastics Institute).
• Local production gives 30% lower logistics costs compared to imported bioplastics.
• Supports UN Sustainable Development Goals 12 and 13.
• Recycling dairy waste prevents waterway contamination with nitrates and reduces methane emissions.
• Fruit waste feedstock reduces raw material costs by 15–20% compared to synthetic acids, saving $200 per ton.

Integrations

Partnerships with municipalities and wineries to ensure a steady raw material supply. A network of 50 collection points in the Mediterranean planned by 2027 for feedstock stability. EU Green Deal support could unlock grants up to €10 million for scaling.

Deployment & Operation

Containerized processing units. Reference plant scales cited: a small Cyprasein plant with a capacity of 5,000 tons/year can reduce disposal costs for local farms by 40%; a 10,000-ton/year plant is used as the reference unit for job creation. Ideal production areas are hot-climate regions where dairy and viticulture thrive: South America, Australia, the southern U.S., southern Europe, and Israel. Supply-chain stress tests simulate a 30% raw material reduction, driving interest in widespread adoption by 2027–2030.

TRL

TRL 4 — assigned internally, 2026-08-06.

The source material does not state an explicit TRL value; this rating reflects that Cyprasein is developed and in production-economics planning, with water-resistant (hydrophobic coating, planned 2026) and heat-resistant (up to 80 °C) versions under testing, and scaling targeted for 2027–2030.

Market Potential

Global bioplastic demand is growing at 10% annually, reaching 2.8 million tons in 2024, and is expected to reach 4.2 million tons by 2029 at a CAGR of 15.2%. Global bioplastic sales hit $10.5 billion in 2024, projected to reach $22 billion by 2030 as environmental regulations tighten. Cyprasein could capture 5% of the market, or 210,000 tons, equating to $1.26 billion annually at $6/kg. In the Mediterranean, processing 20% of grape pomace (2 million tons) could generate $12 billion in revenue by 2030. Competing traditional polymers are priced at $1–2/kg; scaling production could reduce Cyprasein costs by 20%.

Typical Project Economics

• Production cost $0.4–1.3 per kg against a market price of $2–6 per kg, yielding up to 80% margins.
• Producing 1 ton saves $500 on disposal and generates up to $6,000 in revenue.
• Processing 10,000 tons of waste saves up to $1 million in disposal costs and generates up to $60 million in revenue.
• A 5,000-ton/year plant reduces disposal costs for local farms by 40%.
• Farmers and winemakers earn $10–20 per ton of waste.
• Up to 500 jobs created per 10,000-ton/year plant in hot-climate regions; in Greece or Spain, processing local waste could create 500 jobs per 10,000-ton/year plant.
• Processing 10,000 tons of dairy waste in Greece cuts methane emissions by 1,200 tons of CO₂-equivalent annually, equivalent to the emissions of 250 cars (Eurostat data).
• Grape pomace recycled in the Mediterranean could save €60 million in disposal costs by processing 20% of 10 million tons of waste.
• Fruit waste as feedstock reduces raw material costs by 15–20% versus synthetic acids, saving $200 per ton.

> Discrepancy in source: disposal savings are stated as "$500 per ton" in one place, while the aggregate figure is "up to $1 million" for 10,000 tons (i.e. $100 per ton, matching the stated $50–100 per ton disposal cost). Both figures are reproduced.

Risk Factors

• Seasonal fluctuations in grape pomace supply. Stated mitigation: diversify raw materials with apple and citrus waste, available year-round, plus a network of 50 collection points in the Mediterranean by 2027.
• Limited water resistance under prolonged liquid contact. Stated mitigation: the 2-year degradation timeline suits most products' shelf life, especially perishables; a hydrophobic-coating version for medical packaging is planned by 2026.
• Scaling production. Stated mitigation: supply-chain stress tests simulating a 30% raw material reduction, with adoption targeted for 2027–2030.
• Product shelf-life constraint: the material is suitable for products with a 1–2-year shelf life, since it degrades within that window.
