Surfing is global. It has no gender, age or socio-economic boundaries. Although surfers come from many different backgrounds and approaches, they all rely on the same things. Surfers are like a family connected by the deep respect for and love of the ocean. As most surfers are conscious about environment and thus trying to keep plastics out of the beaches and oceans and trying to create healthier environment, there is demand for production of sustainable surfboards (‘Moss Research Announces “Industry-First” Sustainable Surfboards’, 2011). As surfing is an interaction with simple forces of nature on a sustainable level, it has the image of very pure sport. There is no trace left on the face of crashing wave by a surfer, however, the surfboard production industry has a great impacts on natural environment (Sullivan, 2007). | Surfing is global.

The typical modern surfboard is made of polyurethane foam, polyester resin and fibreglass. The process is mostly carried out by using environmentally harmful products. A lot of materials are wasted and those are un-recyclable. During the manufacturing, the workers are surrounded by dust and toxics. Prolonged exposure to fibreglass and polyester resin is harmful for health of shapers as it may be cause of lung cancer (‘Moss Research Announces “Industry-First” Sustainable Surfboards’, 2011; Sullivan, 2007; Vartiainen, 2018). | The typical modern surfboard is made of polyurethane foam, polyester resin and fibreglass.

# '''Super Sap''' made by Entropy Resin is made of byproducts of the pulp and paper industry and the biofuels industry, with total biological content varying between 25-50% depending on the specific resin used. Research showed 50% reduction of CO2 emissions in Super Sap resin compared to normal resins (Michelena, Graham-Jones, Summerscales, & Hall, 2016). | #'''Super Sap''' made by Entropy Resin is made of byproducts of the pulp and paper industry and the biofuels industry, with total biological content varying between 25-50% depending on the specific resin used.

# '''Bio-based resin''', however, cannot be 100% ecological because it is based on petrol. Surfboard constructors argue that bio-based resins are good but have also some disadvantages such as higher price, lower strength and not being as white as epoxy resins (Vartiainen, 2018). | #'''Bio-based resin''', however, cannot be 100% ecological because it is based on petrol.
