00:01Anywhere where people are using portable toilets there is urine that ultimately
00:05could end up in sewage but instead what we do is we make sure that doesn't
00:10happen. We process the urine either on site or at our lab in Bristol and we
00:14recover the nutrients and the micronutrients and turn them into a
00:18sustainable fertilizer. So you know the reason that we do that is because we are
00:22incredibly reliant on fertilizer in the UK. We need it to grow our food, we need
00:26it to grow trees and crops but typically fertilizers come from overseas or they
00:31are produced using really energy intensive methods and then at the same
00:35time we're producing you know these nutrients naturally in our bodies and
00:38traditionally they are tankered away or go to sewage and you know we've all seen
00:42the sort of terrible state I suppose of the sewage system in the UK and
00:47nutrients can end up leaching into rivers they can cause all kinds of problems
00:50and we don't want that to happen so we work with people to make sure that their
00:54waste is recycled and put to use for example in growing trees and crops. We
00:58will be putting the seeds into our compost so the compost is mixed with our
01:03fertilizer we put the seeds in and then they will actually be in the kind of in
01:07the root trainers for a whole year so we will be monitoring see how they
01:11germinate see how they grow taking regular measurements because part of this
01:15trial is collecting really robust data and then after a year the trees will
01:20actually be moved out into the field so what we have here is some Scots pine some
01:25baby Scots pine they might look a little bit like baby Christmas trees but this
01:29is a native UK species and so we will take we're growing those from seeds and
01:34then after a year we will put them in the ground so after a couple of years the
01:38Scots pine we grow will look like this. So if you if you want to deliver you know
01:42biodiversity uplift if you want to mitigate climate change using the tools that
01:48you've got in the landscape you have to work with farmers. We are from the
01:51farming community and we understand that farmers need assistance to transition to
01:58a new form of farming so that's manifesting in the way the government are
02:03introducing a new agricultural subsidy system called the sustainable farming
02:07scheme and I think the transition is confusing and complicated for an awful lot of
02:12farmers and that's where we can help so they have increased obligations to have
02:18more trees on their farm well we're here to deliver that and we will do that for a
02:23farmer we'll give the farmer a grant. We take the urine so from say a big event we
02:28can process on site or take it away from their toilets and we put that through
02:33initially a biological system so the nutrients are actually recovered from the
02:37urine so it is no longer a waste product at that point because we've recovered the
02:41nutrients from it. We then bring in the biochar as a sort of ingredient so all of
02:45our biochar is from sustainable sources so we've got the kind of recovered
02:49nutrients you know they're not going to sewage anymore we've saved those and we've
02:52got a sustainable biochar and we have a kind of novel process that combines them
02:56together to create this sustainable slow-release fertilizer.
