Waiākea Introduces Algae-Based Ink for Beverage Labels to Reduce Fossil-Derived Pigments

Waiākea Hawaiian Volcanic Beverages has introduced a new sustainability initiative aimed at reducing the environmental impact of packaging materials. The company recently began using labels printed with algae-based pigment, replacing traditional carbon black inks that are typically derived from fossil fuels.

The pigment is incorporated into a commercial ink formulation known as ACTExact UV Black Algae Ink. The technology was developed through a collaboration involving Living Ink Technologies, packaging and coatings specialist ACTEGA, and printing supplier NextGen Label Group. According to the companies involved, the new formulation allows algae-derived pigment to function within existing commercial printing systems used in consumer packaging.

The launch represents the first known commercial deployment of algae-based ink on beverage labels. While packaging innovations often focus on recyclable materials or lightweight containers, the environmental footprint of printing inks has historically received less attention despite its reliance on fossil-derived ingredients.

Carbon Black and Its Environmental Impact

Traditional black ink relies on carbon black, a pigment produced by partially combusting petroleum or heavy oil residues. Carbon black is widely used not only in packaging inks but also in automotive tires, coatings, cosmetics, and plastics.

Global production of carbon black exceeds 33 billion pounds annually. Its manufacturing process is energy-intensive and generates significant greenhouse gas emissions. Life-cycle assessments indicate that producing one kilogram of conventional carbon black results in approximately 3.75 kilograms of carbon dioxide equivalent emissions.

Because black ink is one of the most widely used pigments in the packaging and printing industries, replacing even a portion of conventional carbon black with alternative pigments could significantly reduce emissions associated with consumer goods packaging.

Algae-Based Pigments as a Carbon-Negative Alternative

The pigment used in Waiākea’s new labels is derived from algae, organisms that naturally absorb carbon dioxide as they grow. This biological process allows the pigment to have a negative carbon footprint when evaluated through life-cycle assessment.

According to Living Ink Technologies, the algae pigment used in the ink formulation has a climate impact of approximately minus 4.16 kilograms of carbon dioxide equivalent per kilogram of pigment produced. The carbon-negative result reflects the CO2 captured during algae cultivation combined with emissions associated with processing and manufacturing.

If algae-derived pigments were used to replace the global supply of carbon black used in inks and pigments, the potential emissions reduction could exceed 100 million metric tons of carbon dioxide equivalent annually. That level of reduction would be comparable to removing roughly 25 million passenger vehicles from the road.

Although full replacement is unlikely in the near term, the figures illustrate how material innovations in seemingly small components of packaging can deliver meaningful climate benefits when scaled across industries.

Scaling Sustainable Materials in Consumer Packaging

The introduction of algae-based ink builds on Waiākea’s broader sustainability strategy, which has focused heavily on packaging materials and supply chain impacts.

The company was among the first bottled water brands in North America to introduce bottles made from 100 percent post-consumer recycled polyethylene terephthalate, commonly known as rPET. Using recycled plastic reduces reliance on virgin fossil-derived plastics and lowers greenhouse gas emissions associated with plastic production.

Waiākea also developed its OceanPlast bottle, which uses plastic collected from coastal communities where waste management systems are limited, and materials are at high risk of entering marine environments. The recovered plastic is processed and reintroduced into manufacturing supply chains to create new beverage containers.

In addition to material innovations, the company has implemented logistics tracking tools designed to improve transportation efficiency. The system helps optimize delivery routes and reduce empty return trips, lowering fuel consumption and transportation emissions across distribution networks.

Broader Implications for the Packaging Industry

Packaging remains a major contributor to global industrial emissions. While much attention has been given to plastics recycling, renewable materials, and lightweight packaging designs, inks and coatings are also important components of the overall environmental footprint.

Printing inks must meet strict performance requirements, including durability, adhesion, curing performance, and compatibility with high-speed manufacturing equipment. For this reason, developing alternative pigments that function within existing industrial processes can require years of testing and engineering.

The algae-based ink used in Waiākea’s labels was developed over several years to ensure that it could perform reliably in commercial printing systems without compromising packaging quality or production efficiency.

As consumer goods companies face increasing pressure to reduce supply chain emissions, materials innovations such as bio-based pigments may play an important role in achieving climate targets.

Encouraging Wider Adoption Across Industries

One notable aspect of the initiative is that Waiākea has chosen not to retain exclusive rights to the algae-based pigment technology. Instead, the company intends to open access to the innovation through its development partners, encouraging other brands and industries to adopt the material.

The open approach could accelerate the use of algae-derived pigments in sectors such as food packaging, cosmetics, textiles, and printing, where carbon black remains a standard ingredient.

Wider adoption would be essential for achieving meaningful climate impact. While the emissions reduction associated with a single product line may be modest, the cumulative effect of replacing fossil-based pigments across global supply chains could be substantial.

The Growing Role of Bio-Based Materials

The development also reflects broader interest in bio-based materials as industries seek alternatives to fossil-derived inputs. Algae have attracted particular attention because they grow rapidly, require limited agricultural land, and absorb carbon dioxide during cultivation.

Researchers and manufacturers are exploring algae-derived materials for applications including textiles, pigments, biofuels, plastics, and carbon capture systems.

However, scaling these technologies to industrial levels remains a challenge. Production capacity, cost competitiveness, and supply chain integration will determine whether algae-based materials can move from niche applications to widespread commercial adoption.

For companies pursuing net-zero targets, innovations such as algae-based inks illustrate how decarbonization efforts increasingly extend beyond energy use to include the materials embedded within everyday products.
