The Waste Biz: Composite Lumber Combines Agave Waste, Recycled Plastic

Building materialsΒ made from waste and/or recycled materials are nothing new: my backyard fence features boards of a composite lumber made from plastic milk jugs and wheat straw. Β The choice of materials can make a big difference, though, in terms of durability and weight. A start-up in Jalisco, Mexico, thinks agave bagasse (the fibrous waste left over after squeezing out juice) mixed with waste plastics hits the sweet spot. According to ScienceDaily, the company, Plastinova, believes its composite achieves “a medium point between [wood and aluminum] in terms of physical properties while reducing the cost, as well as recycling organic and inorganic waste.” They envision the material being used for formwork, or for building products like outdoor furnishings. I’m guessing decking or fencing might be good choices, also.

While they’re located in an area where agave is widely grown, the bagasse has traditionally been burned to run boilers. Β So, it’ll be interesting to see how the market rules here: will Plastinova be able to pay enough for this material to keep it out of boiler fires, and still price their product competitively? If it works as advertised, I don’t see why not: I know plenty of people love this concept and are willing to pay a premium for materials. In my case, a material I didn’t have to paint was very appealing!

    I am sure that the only way that agave waste is used to replace plastic instead of running boilers is if it’s more lucrative to do so. Having said that, it can help but think there are more cost-effective ways to run boilers than to burn agave plants.
