unless the rubber or the polyurethane really do leech toxins, in which case the spongy permeable structure of the bricks has a lot of surface area that's very good at leeching a lot of them.

@atvheads what do you mean? the company is buying those tires.

@enlightendbel the "4/5 of all microplastic in the ocean comes from tires" claim seems very non-credible, given the fact that all the common types of plastic break down into microplastic in the ocean, many objects (foils and foams) quite quickly so, and that the amount of other plastic produced is much larger than the amount of tires. worn tire dust is going to stay mostly on land, and the only plausible way lots of tires would get into the ocean is deliberate sea-dumping of collected tires (because of the threats mentioned in the video - very large and very toxic fires, or breeding puddles for mosquitoes). but as far as I'm aware, tires are a relatively popular fuel for power plants and some factories (typically not featuring good enough exhaust filtration, but who cares, it's energy). I haven't heard of tires in particular being dumped in the ocean, and it seems unlikely to me to occur on a very large scale, compared to other garbage dumping, or the unintentional ocean pollution with light bits of plastic litter that gets blown and washed around on land and into rivers.

8:55 if she actually said that the business is "on the verge of becoming profitable", and that's not a misquote of her saying that it's about to break even (pay for all costs incurred so far), then she is deep in the hole with that business. because that's a hell of a lot of money invested in all those machines. most of the businesses in these videos have only one or two machines, this one has a dedicated machine for almost every step of the production process, plus an industrial generator. the machines are likely to be european or asian imports and are traded at world market prices, which are expensive for nigerians. where did the money come from?

@Entergalactic so you mean to say that by "on the verge of becoming profitable", she means that profits are about to surpass the loan payments? 🙄

@nikushim6665 5:57 the video claims that it is polyurethane, and it does make sense that it would be. PU can be adapted to all sorts of applications (including remaining moderately flexible in this application), and I'm pretty sure it's easier to work with than polybutadiene (synthetic rubber). the tires themselves contain polybutadiene though, their rubber content is typically half synthetic.
