Transphytoism

You’ve heard of transhumanism? The concept of modifying humans with technology to make ourselves stronger and more able. Some people have argued that that’s exactly what prosthetics are, whilst others think the tech has to advance further. But, can we do it with plants?

New tech has ripped bits out of a venus fly trap and integrated them into a new robot to mechanise a grabbing claw. It is, if you like, a Frankenstein’s monster of the plant world, a terminator to terrorise all triffids. Or, you know, a cool little gadget. A bit like a litter-picker.

Plastic waste and the pandemic

Our use of plastic is changing worldwide – and not for the better. Many governments with bans or restrictions on the consumption of single-use plastics have withdrawn the bans and, during the COVID-19 pandemic, our consumption of them in the form of personal protective equipment (PPE) has escalated, with estimates as high as sixfold increases – much is unrecyclable, and domestic and small business users have no defined waste policy, with much of it ending up in recycling where, due to its medical nature, it cannot be processed. This causes bottlenecks in the recycling system, or illegal waste dumping.

Latex gloves are made from the rubber in rubber trees: a polymer of isoprene that is readily broken down in nature. However, not all plastics are so readily biodegradable. Some, such as nylon (also used in gloves), are a halfway house: they can decompose under warm, wet conditions, but are relatively sturdy; others, such as polypropylene (PP) (used in gowns and masks), which is a hydrocarbon with no oxygen nor nitrogen linkages to help make it compostable, may stick around for thousands of years.
