The ever-ongoing quest to make Spektrum products ever more sustainable has led us to the use of bio-based materials derived from plants throughout our collections.

For our Performance Eyewear collection this means constructing our frames in oil extracted from the amazing castor bean. Our high-performance frames are made mainly from castor oil and reduces the overall CO2 emissions by an impressive 46% compared to conventional materials. The carbon in castor oil is also 100% derived from atmospheric CO2 and not from CO2 locked in ancient fossils. Our material is also lighter and more durable than comparable materials delivering increased performance and comfort.

Castor beans are a fantastic crop, able to thrive in meager soils where other plants won’t survive, or animals can graze. Our castor beans are fully traceable, sustainably grown in India and poses no competition with food, causes no deforestation or use any GMO.


Our suppliers are committed to the Paris climate agreement and partners of the Pragati Project in India.


The castor beans are grown in soil where plants for food won’t survive and they are also very drought resistant and they have no nutritional value.


Castor grows in arid regions where this is little forest growth.


  • Good agricultural practices
  • Better Water Management
  • Improved Waste Management
  • Respecting Human Rights


No forest areas are cleared or converted to grow castor beans.


The castor beans we use are grown without any genetic engineering or modified fertilizer.


Spektrum’s frames are made of plant-based non-food derivates from corn. The details on our frames are made out non-food resin and castor bean derivates. 64% of the product is produced of plant based bio material and recyclable materials. Through our process they are modified into polymers and become pellets that are injected with color. The dye process ensures a superior durability and depth of colour for all our frames. This vastly improves colour performance, durability and scratch resistance. The process also spares workers and our environment from exposure to hazardous solvents and chemicals.
