Researchers have found a technique to rework a big waste output from soy biodiesel crops right into a priceless useful resource. The group behind it has developed a course of to transform matter natural non-glycerol (MONG), a byproduct of biodiesel manufacturing, into copolymers appropriate for 3D printing filaments.

The worldwide demand for renewable power sources has led to a rise in biodiesel manufacturing, leading to a big quantity of waste byproducts equivalent to MONG. Historically, MONG has been landfilled, posing environmental challenges and financial inefficiencies. The research presents a two-fold answer: a technique to stabilize MONG to be used in 3D printing and a discount within the artificial polymer content material of pure fibre composites (NFC).

The researchers characterised soy MONG and evaluated its potential as a copolymer to supply 3D printing filaments. They targeted on enhancing the thermal stability of MONG by way of two pretreatments: acid therapy and a mixture of acid and peroxide. The latter resulted in a stabilized paste with decreased cleaning soap content material, elevated crystallinity, and the formation of low molecular weight small chain fatty acids, making it a great candidate for copolymerization with thermoplastic polymers.

The research’s findings point out that acid and acid + peroxide therapies successfully break up cleaning soap, scale back water solubility, and improve glycerol content material in MONG. The therapies additionally facilitated the oxidation of fatty acids and the formation of small chain fatty acids, that are extra appropriate for 3D printing purposes. Notably, the acid + peroxide therapy led to a rise in formic acid and oxirane focus, suggesting profitable epoxidation, a key issue for enhancing the thermal stability of MONG.

The researchers additionally carried out a complete evaluation of the MONG’s physicochemical properties, fatty acid profile, and thermal stability. The outcomes had been promising, exhibiting that handled MONG might be a viable various to artificial polymers in NFC for 3D printing. The research concludes that the utilization of MONG in 3D printing not solely provides worth to a biodiesel waste product but in addition contributes to the event of sustainable and carbon-neutral composites.
