Am I in trouble over plastic roads?

Apparently I might have dropped my council in it as a result of my innocent enquiry about plastic roads. I wrote a short email to my local representatives to ask whether the council had looked at the use of waste plastic additives in road surfacing and in their reply I was told that:

Several trials around the Country have taken place and the feedback we’ve received so far is that the material has failed due to various such as temperature issues with the mixing of the addictive.  Therefore we’ve decided to hold fire and continue to monitor for further developments.  We do not want to waste tax payers monies on a treatment that may have a shortened design life.

I'm guessing that something is missing between "various" and "such as", but that's how it came. Well, further investigation was required, so I did a search of the internet and couldn't find any related research about failure rates in asphalt using plastic additives. The obvious next step for me was to ask the company about it, and they were let's say surprised.

Reading the LA's response carefully, it seems to imply that the problem isn't with the additive but with the production process. I understand the local authority's need to be cautious, but where's the evidence for failure? If it's the process, then who is monitoring the process in order to get it right? It would be nice if they had responded with some data. All the research I've been able to read points to longer lifetimes for these surfaces not shorter ones. Polymer modified bitumen has been around for some time, but using plastic waste diverted from landfill and recovered from the oceans is new. So the process ought to be within the grasp of industry.

20M tonnes of asphalt is produced in the UK each year and using waste plastic as an additive could recycle 60,000 tonnes of waste that currently goes into landfill. So I think it must be worth pursuing this technology and if there is an issue, then let's see the evidence.

I often wonder if studying Environmental Science in the late seventies was a decade or two too early. Were we ahead of the curve in a world that was only just waking up to some of the realities of what we were doing to our environment? Perhaps it's still true given that we have an incumbent in the White House who denies climate change, has relaxed EPA targets for the coal industry and apparently would prefer fossil fuels rather than have a wind farm obscure his view across a golf course.

Anyway, I still consider environmental stuff to be an area of interest, and it's clearly something that should concern us all. I keep an eye on the developments of ocean clean-up programmes, and would one-day love to build a near-zero carbon footprint house. Personally I'd like to see all new build housing have solar panels and battery storage, rainwater collection and recycling. Although I've never investigated it, I wonder if that's part of the reason some new developments have ponds and lakes so that rather than sending all the rainwater into the sewer system, it diverts to a water feature.

Back to the point, plastic roads. While we look to reduce the amount of unnecessary plastic used in our day-to-day lives, we also need to think about what to do with the accumulated waste, and that's where plastic roads come into the picture. Some time ago I saw a short news item about a company that was investing in and developing the use of plastic waste as an additive for road surfacing. A recent article in the Guardian reminded me of this and I did a quick search for the company.

It's working. Road surfaces are being laid across the country using a pelletised form of recycled plastic as part of the mix. Not only is this using waste, it's also potentially extending the life of the road surface and of course reducing the usage of raw materials. You can read more about it on the company's website: Macrebur.

I've written to my local councillors to see if my council is exploring the idea and I hope they either are or will be doing so.

Got an old bike?

I used to cycle a lot. Well around 120 miles a week, but that is a long time ago. I actually came to cycling quite late, never having a bike when I was a kid. At university I learned the skills to ride by buying a bike and getting back on it every time I fell off until I stopped falling off!

Sadly my cycling days are long gone, mainly due to a knee that reacts rather painfully to the stop and start routine. Oddly I can ride a bike at the gym without problems, but on the road eventually my knee complains and I have to stop. So my bike sits in the shed along with Anne's and two of Ally's bikes.

We're moving soon and I have been thinking that painful as it would be, it's time to get rid of these bikes and clear some space. But I didn't really want to throw them in a skip. Today, while I was looking at something else I came across an organisation that takes old bikes and reuses them in Africa. The main collection point is on Colchester, just an hour away from me. I think I've found a new home for my precious Raleigh tourer!

Bicycle Aid for Africa sounds like a great idea, and they don't just want your old bike, they are interested in bike tools and general workshop tools. If I'm honest I could probably supply a complete small workshop if I took the time to sort out all the tools I've inherited and bought over the years. So maybe a few spanners and hammers might find their way out of my garage and into a more regular place of use.

If you have an old bike, don't throw it away, consider instead donating it. The website has a list of UK-based bike recycling charities if you're not close enough to one of their own collection points.
