Roads Can Be Recycled Forever, Why Don't More Cities Do It? | World Wide Waste | Business Insider

I toured an asphalt research lab when I helped lead the second year ASM camp at Rowan University a few years back. Before that I'll admit that I hadn't put much thought into the different compositions that make up asphalt roads or the research that went into 'perfecting' the recipes used in road building.

Today's video introduces us to Green Asphalt, a company that is taking asphalt removed from roads and processing that asphalt into a reusable product, preventing hundreds of thousands of tons of asphalt from landfills every year.

I think I wrote it a few weeks back, but man, we make a lot of waste.

5 Kinds of Glass Made by Nature

Obsidian...opals...tektites...fulgurites (including their subsets, apparently)...glass sponges

I knew about a couple of those, but I'll admit that I'd never heard of glass sponges or tektites, and I didn't really think of opals being glass.

Inside London's 'zero waste' restaurant | FT Food Revolution

We produce a great deal of waste. That's not a very debatable statement.

This video visits a London restaurant that is attempting to have zero waste from his restaurant.

From making the pendant shades out of waste seaweed to forming their own pottery on site and glazing that pottery with ground up waste wine bottles, the restaurant attempts to have nothing thrown away from day to day.

They ferment much of their food scraps that would normally be wasted and thrown away.

They upcycle their plastic bags into serving plates.

Somehow the ice cream is made from waste bread.

All in all, it's a place that I would love to study more but that I'm not sure I would actually enjoy. Some of the cuisine seems to be awfully fancy, and I'm not sure that my tastes are in line with.

Check out Silo if you're ever in London - and if you can actually get a reservation.

Making your own impact tester

So, a bit of a story...

I was watching this video on trying to build 3d printed objects by using half layer offsets...


...and got halfway through when I saw the YouTuber test his products with what seemed to be a homemade Charpy-esque impact tester.

5:38 in the above video

That homemade impact tester is something we've been talking about in our summer camps as a hypothetically simple thing to build, but our discussions tend to be fairly abstract and general - not at all specific as to plans that could be followed. This, however, looks to be something fairly specific and even branded by CNC Kitchen's blue and white logo.

So I went searching and came upon this video by CNC Kitchen that shows a homemade tensile/compression tester at about 8:15, a three-point bend tester at 10:45, and the same impact tester at 12:10.


So onward I went to find plans for the various testers.

I did find a video showing how to make the tensile/compression tester.


...and another for the 3-point bend tester.


...but I wasn't able to find a video for how to make CNC Kitchen's impact tester. Luckily, the impact tester's plans are available online.
