Sealants and adhesives composed of biomass-derived materials

13/07/2026
Nowadays, environmental concerns are influencing every industry and every stage of the manufacturing process. Companies are increasingly looking for ways to reduce their environmental impact by selecting more sustainable raw materials and components. Every element of a product, including adhesives and sealants, plays a role in improving its overall environmental footprint.

As plastic-related industrial waste continues to grow, developing adhesives based on more sustainable raw materials has become an important step toward reducing reliance on fossil resources and supporting a more circular economy.

01. What are biomass-derived materials ?


Biomass-derived materials are materials manufactured from renewable biological feedstocks rather than conventional fossil-based resources. These feedstocks originate from recently living organisms and include plant-based sources such as vegetable oils, sugars, starches, cellulose, lignin, natural resins, as well as agricultural and forestry by-products.

Through a series of chemical, biochemical, or thermochemical conversion processes, these renewable resources are transformed into chemical intermediates and monomers that can be used in the formulation of industrial products, including adhesives, sealants, coatings, and resins.

Unlike petroleum-derived raw materials, biomass feedstocks are continuously regenerated through natural biological cycles. Depending on the manufacturing process, biomass-derived materials may partially or fully replace fossil-based ingredients while maintaining equivalent mechanical, chemical, and thermal performance. Advances in green chemistry and bio-refining technologies have enabled the production of high-performance bio-based polymers compatible with demanding industrial applications.

One of the main environmental advantages of biomass-derived materials lies in their carbon origin. During their growth, plants absorb atmospheric carbon dioxide (CO₂) through photosynthesis and incorporate this carbon into their biomass. When biomass-derived materials reach the end of their life and are incinerated, the CO₂ released corresponds largely to the carbon previously captured during plant growth. This creates a short-term biogenic carbon cycle, which is generally considered to have a lower net impact on atmospheric CO₂ concentrations than the extraction and combustion of fossil carbon.

It is important to note that bio-based does not necessarily mean biodegradable. The term bio-based refers exclusively to the renewable origin of the raw materials used, whereas biodegradability depends on the chemical structure of the final material and the environmental conditions under which it is disposed of. Consequently, a biomass-derived adhesive can offer the same durability, chemical resistance, and long-term performance as a conventional fossil-based adhesive while reducing dependence on non-renewable resources.

02. Types of materials


At ThreeBond, we have developed a range of adhesives and sealants incorporating biomass-derived raw materials as part of our commitment to more sustainable material solutions. By integrating renewable resources into selected formulations, we aim to reduce the use of fossil-based feedstocks while maintaining the high levels of performance, reliability, and durability required for industrial applications.

Our bio-based technologies rely on carefully selected renewable raw materials, each providing unique chemical and functional properties that contribute to the performance of our products. Among the biomass-derived materials currently used in our formulations are :

  • Castor oil : a renewable vegetable oil rich in ricinoleic acid, widely used as a bio-based building block for polyurethane and resin systems, providing excellent flexibility, durability, and chemical resistance.
  • Scallop shells : a natural source of calcium carbonate recovered from food industry by-products, contributing to resource valorisation while serving as a functional mineral filler in adhesive formulations.
  • Pine resin : a naturally occurring resin obtained from pine trees, valued for its excellent tackifying properties, adhesion performance, and renewable origin.
  • Soybean oil : a plant-derived renewable resource used to produce bio-based polyols and other chemical intermediates, helping reduce dependence on petroleum-derived raw materials while maintaining high-performance characteristics.
Through continuous research and development, ThreeBond continues to explore new bio-based raw materials and innovative formulation technologies to further increase the renewable content of its products without compromising quality or application performance.

03. Contribution to more sustainable process


Sustainability extends beyond the selection of renewable raw materials. The way products are designed, manufactured, and applied also plays a significant role in reducing their overall environmental impact. Adhesives and sealants can contribute to more sustainable manufacturing processes by improving production efficiency, reducing material consumption, and extending the service life of assembled components.

Compared with conventional mechanical fastening methods, adhesive bonding can reduce the number of parts required in an assembly, simplify manufacturing operations, and enable the use of lightweight materials. These advantages can help lower energy consumption during production while supporting the development of lighter and more efficient products in industries such as electronics, automotive, aerospace, and renewable energy.

In addition, durable bonding and sealing solutions improve the reliability and longevity of products by protecting sensitive components against moisture, chemicals, vibration, dust, and thermal cycling. Increasing product durability helps reduce maintenance requirements, limit premature replacement, and decrease material waste throughout the product's life cycle.

Many modern adhesive technologies also contribute to cleaner and more efficient manufacturing by reducing volatile organic compound (VOC) emissions, minimizing process waste, and enabling lower curing temperatures or faster curing times. These improvements can translate into lower energy consumption, increased productivity, and a reduced environmental footprint across manufacturing operations.
