Pothole Repair – with plastic

From the BBC:

Recycled plastic has been used to resurface a road in Flintshire as part of a trial scheme. Pellets made from the waste material were added to the asphalt laid at a junction in Connah’s Quay, UK. Flintshire County Council wants to reuse items from residents’ bins which are difficult to recycle and would otherwise go to landfill sites.

Officers have been working with a Scottish firm which produces plastic pellets from bottles and bags to be melted into the asphalt as a binding agent in place of bitumen.

Plastic Waste – build our future

Scidev.net reports how just a few years ago, Nzambi Matee decided to do something about the plastic pollution that she saw all over Kenya. Now, she has designed and built a thriving recycling and brick production facility, and her social enterprise Gjenge Makers has recycled plastic waste weighing more than five female elephants.
This week on Africa Science Focus, reporter Michael Kaloki takes a tour of Matee’s workshop – and finds out how she is tackling Kenya’s pollution problem, one brick at a time.

Paint Your Cattle 👁️

Cattle Eyespots

Recent fascinating research from Botswana has looked at the effects of painting eyes on cattle.

The researchers have shown that eyespots painted on cattle rumps were associated with reduced attacks by ambush carnivores (lions and leopards). Cattle painted with eyespots were significantly more likely to survive than were cross-marked and unmarked cattle, despite all treatment groups being similarly exposed to predation risk. While higher survival of eyespot-painted cattle supports the detection hypothesis, increased survival of cross-marked cattle suggests an effect of novel and conspicuous marks more generally.
“To our knowledge, this is the first time eyespots have been shown to deter large mammalian predators. Applying artificial marks to high-value livestock may therefore represent a cost-effective tool to reduce livestock predation.”
