How toymakers are taking the lead on bio-based plastics.

How toymakers are taking the lead on sustainable bio-based plastics (Green Dot)Plastics are seemingly the ideal raw material for toys. Theyre relatively inexpensive, easy to clean, durable and can be molded into just about anything a childsimagination is capable of cooking up. While wood, textiles and metals can no doubt still be found in your average toy box, these materials have largely been supplanted by the now-ubiquitous plastic toy. Teethers, rattlers, stack toys, play food and other early childhood toys especially are all reliably made from plastics these days. In this guest post from Kevin Ireland of Green Dot Bioplastics, we learn about how the mass production made feasible by the qualities above has created its own set of problems. As will surprise no one familiar with mass consumption and its green backlash, the products we makeplastics in this caseare prone to unintended consequences.

Environmental degradation, exposure to harmful chemicals and the problem of waste plague all industries. But given the ubiquity of plastic toys in stores, classrooms and nurseries, the toy manufacturing industry faces the twin prospects of having a uniquely massive carbon footprint and the severest consequences for a vulnerable user-base if it neglects to make a change to more sustainable plastics.

Luckily, toymakers are in fact exploring options for using more sustainable plastics over petroleum-based incumbents. The following are some of the most promising spins on an old material, both from a sustainability and performance perspective, that toymakers are exploring with some success:

  • Bio-based plasticslike PLA, PHA and starch polymers made with renewable feedstocks instead of petroleum-based feedstock used in traditional plastics for toys that do not deplete our finite natural resources.
  • Biocomposite plasticscombine natural fibers or wood flour with recycled, biodegradable or biobased plastics to create durable weather-resistant toys.
  • Biodegradable plasticslike PLA, PHA or Green Dots Terratek Flex compostable soft plastic elastomer can be used to make toys that can be returned to nature when their useful life has ended.

Why toymakers are on the lookout for more sustainable plastics

A sort of symbolism plays into the exploration of alternative,sustainable plastic materials for toys. When toymakers break from petroleum-based feedstock for the toys, and instead explore more environmentally-friendly raw materials, they signify an interest in what sort of planet their users will grow up to inherit. Sustainable plastics, made with bio-based, biocomposite or biodegradable raw materials reflect a desire to preserve our planets natural resources and ensure their toys leave a legacy of innovation and care rather than waste and degradation. And, it turns out, what initially makes sense about toymakers exploring sustainable plastics makes even more when you think about what theyre subbing out in exchange.

Many of the chemicals used to give plastic their flexibilityplasticizers as they are knownhave been shown to be endocrine disruptorsand linked to the development of tumors, birth defects and developmental disorders. Both the United Statesand theEuropean Unionhave had a ban on the use of certain types of phthalates for years. Especially for young children, there is a fear that chewing on or heating the toys can exacerbate the harmful effects of exposure to chemicals like phthalates, bisphenol A (BPA) and heavy metals. Removing these chemicals, as well as others like PVC, should be a major thrust for toymakers looking to avoid exposing children to potentially harmful substances during the important period of early childhood development.

Once toymakers begin exploring options for less toxic materials, they often also find an unexpected marriage between sustainability and performance. Biocomposite materials which utilize natural fibers such as wood pulp, flax, starch and others can bring performance characteristics such as durability, natural feel and even buoyancy to the fore. Exploring sustainable plastics made with biocomposite materials gives toymakers a degree of flexibility and chance for creativity thats lacking even with already versatile traditional plastic formulations.

How Green Dotis helping toymakers utilize more sustainable plastics

BeginAgain Toys ( @BeginAgainToys) Scented Scoops Ice Cream play set and Green Ring Teether

BeginAgain was looking for a soft plastic material that was free from toxic plasticizers. Green Dots Terratek Flex made immediate sense. Not only was it certified to be safe from phthalates, bisphenol A, lead and cadmium, but the starch-based material was also ideal for scenting and retained scents longer than traditional plastics. And because the material is biodegradable, toy parts made with Terratek Flex can be returned to nature when placed in a composting environment following their useful service life.

Lukes Toy Factory ( @LUKESFTY) Toy Trucks

Lukes Toy Factory was looking for a biocomposite material for their toy trucks and trains. They wanted something with a natural wood look and feel that could also be injection molded to make the parts of the vehicle. They needed a material that could be colored to avoid the problem of peeling paint. They also wanted a material that would be durable even if left outside. Luckily, Green Dots Terratek WC meets all of these requirements. Thewood-plastic composite combines wood and recycled plasticin a small pellet form, which is ideal for injection molding.
