people new to the city because that's where the jobs the money and other opportunities are. but the planet's metropolises are being stretched to that limit . more than half the world's population live in cities by twenty fifty despicable right. that's more than six billion people. over the next forty years cities who gobble up natural habitat. means more transport buildings more waste more pollution. many of those moving to cities and rural poor they join the one point six billion people living without adequate shelter. it's vital that you find sustainable ways to deal with this rapid at my station. where plastic waste. it's french. for in the water and i'm. poor we're striving for environmental sustainability in the face of urbanization.
over three hundred million tons of plastic is produced each year with only a fraction of it being recycled much of it ends up in landfills polluting urban living environment waterways and ocean. in colombia the money is being diverted into the building blocks of a new environmental pollution. capital city of. eight million people and it is estimated that six hundred fifty tons a day is thrown away every single day i have come to meet. and. called. on the. first hand the problems faced here and of america.
seventy five percent of. when you see. on the ground potential yes a lot of. weekend plans farm all dispersed in order for us to succeed he's going to need a lot of plastic. going along. with. collecting conventionally useful waste. class. so we're in a right now where the recyclers come to bring their plastics and other recyclable products and they weigh them here so that they can be paid. for looking for. organize all of the area over recent years government support has allowed people like the opportunity to upscale and legitimize the industry creating recycling
centers like this one all over the city. on video of the arm motion machine corners of the last stand i'm going to. be losing. credibility because in. the plan the ongoing challenge for paulino and his team is getting the word out. but. thank. you i went to one of the ministers. going almost. on the number of this because she had to give him time you know they want government to leave iraq and. go man when you. see just the way of knowing people and so they respect.
to him it is only time when you are going to be the most to listen to and you really must insist your team is a must also understand that. if given what you had on me and b. and it's an agreement that is a good it is a delight in this what is your. secret on the thing that a good as you in the government. you know material is almost like on the one accords with the sponsor. because also mendez's which is making good use of its waste plastic head to the company headquarters again. welcome to our factory was a plastic thank you this is where we take all the plastic from paulino and maybe even information over the past few years oscar and his team have been refining this waste to make durable building blocks different types of plastic or first ground separately household plastic waste battery packaging and electrical ways such as
old computers and t.v.'s you can feel like you have said from the factory like these. have even been you it's like a giant blunder what would happen to this packaging if you weren't recycling it falls apart as you. for sure is going to learn now we've got all the ingredients now the chef will go to war dan put it together he's the chair oh he has oh sorry not after this is the chef. they will show us exactly the proportions has a secret recipe the ground of plastics are mixed together heated and then compressed into brick shaped molds tell me a little bit about the temperature what how hot are the five things you just get them as you point depends on the music until the last two years it became too long to do on your whorey the grease is very important that the temperature is kept at melting point so as not to burn the plastic and release toxic gases. so let's check this out let's look at it. it looks
like a man. not as heavy but it thirteen i wonder what that was for that or that compounds we started on certain numbers we have a one not a. so now that we have all of these bricks what kind of uses do you have for them. you can make the same thing with these kind of what and where in these going is next i'm going to tell you you will see what we're going to do with. globally as the world capital. city of the hobby. is one of the great. six percent of the land area. people live in them and they don't count on the most. fun on the net. so i'm just the most kind that you plan on when you're not going to go out with me and
they. say that we come to invite a neighborhood in the midst of one of the city's most deprived areas. in their own yes that's a custom we wanted them to. use to catch up with oscar and his friends while my goodness the bricks we just saw in the factory. they're actually constructing into a house for someone who lives here in the community. as well as i thought you were at the plant we're building we now are here and building it's amazing tell me a little bit about what's right now we are in the kitchen i have many meals will be correct i'm sure. this is the bathroom. this house cost five thousand dollars and has been micro financed by the community for whose son lives in the apartment below where. and when i.
see it. because it's fussy always. say go. away. it's literally like life size lego oscars hope is that there's a project will generate interest in the community and encourage future collaboration. is that most. it's that. they're all looks like rock to them. isn't a government in israel to. crack your story. about i mean i mean you're in a dilemma didn't you. this i just can't get over the whole square that i let the bombing where the cable got in or no electricity. so i get out actually a room now it's a kitchen. else he's telling me this is where the closet is going to be here.
with the television on top if you can imagine at all we've got left is the roof and doors so we're pretty close how much plastic is in that house and this house we five girls that is a plus he. has had one of the one you want to know the one in the pews. before the writers. in just under two days the house is almost complete the plan is that a family of four will be able to put together their own home in less than five days so i'm looking up as i look on his daughter's room to them isn't all this is that we're going to the most enjoy the most on the moon comes up to splash because i've already helped to house forty two families displaced by conflict in the town of recycling one hundred twenty tons of plastic in the process tell me a little bit about the magnitude of impact that this project can have if we use
just two percent of the west blasting the world we can change the life of millions of people we can finish their homes enjoy this unit in america in just ten years. that's an enormous number and a huge impact we have to start we have to start step by step. sustainable building materials are being developed globally. is being treated and used to be construction in countries including ethiopia into nature and here in the post. with many strains ten times stronger than steel and a rapid growth cycle of four to five years bamboo is one of most eco friendly building materials on the planet. and the middle east to engineering graduates in gaza have created an environmentally friendly break called green cake this uses coal and wood ashes a philip instead of sand making use of waste that would otherwise be buried in the
ground. and and guatemala one nonprofit has built a school using natural resources and rubbish that would normally pile in landfills the organizations made a system out of all tiles capable of holding thousands of gallons of rainwater materials like these and many paving the way for greener probe are redefining the spaces we inhabit. singapore is a low lying island city state eighty percent of its population live in high rise public housing resulting in one of the highest population densities in the world challenges for rapid urbanization sea level rise and an increasingly chaotic climate is forcing planners and architects posy makers to respond to questions about how cities of the future will cope with growing demand despite the growing pressure on space singapore's been dubbed asia's greenest city so i've come here to
meet some of the people who are hoping it and the title my first stop is a park royal hotel which boasts fifteen thousand square metres of greenery and was completed in twenty third. by award winning architect richard hassel the now in almost every wise being formed by human activity. takes we feel like it's something within our control to suggest why is that building projects can also play a much stronger role in this ship of the earth when you look at like google earth for images from space it is a really deserts you know you see a very bright white shiny area surrounded by dark vegetation buildings like this you would no longer see that you would see the vegetation liar covering the city as well. singaporean government awarded part loyalist coveted green mark the nation's highest environmental situation is part of a wider scheme to promote environmentally friendly buildings and investment into
green city solutions to understand more about why the city's the greenest in asia i want to see what's happening at the grassroots. heard about a nonprofit providing financial education and supporting the growing into community i've come to be to fund my comment i came here trying to get people to go back to basics and i thought as a result of that we. overnight zation globalization and digitize a shiny new he come disconnect so i was trying to create using a space to connect back people and to bring about a spirit of community and it's very strange for our country because we're so top down and that's why my name is called ground up initiating the ground up initiative started in two thousand and nine and secured a piece of land to provide environmental education for people of all ages you know run several workshops and seminars building a community of five mentally gauge citizens thank you for it if you just for
a moment that we're in the middle of. just knocking down your door and in a very want to build on this land that so i told the government to give me a chance to prove that i think singapore needs a different kind of space fifty percent of the world's population now leave in cities and we seventy percent will leave out of my point three billion on my point five billion dollars per year. what do you being where we come where support coming from who wants to work on the land who will clean the rubbish for you obviously environmental issues. in the ground up initiative gardens i mean choice famine volunteers who've come along to get their hands dirty why do you continue doing farming in a way that connects with. doing every day because where they eat food we know exactly where they can throw anything up i realized also people don't appreciate food because maybe to the kids they have never seen this how the fruit is growing
maybe they thought it's just from the supermarket places like this is very good because it makes us go back to the basics what keeps us surviving what makes us try and it's not really about having money it's not really about heavy all the tech stuff but really been able to to understand that you know just be a part of equal. system seeing how things are grown for example it makes me start to are a lot of other questions like how where things come from so if i use a paper i stop to think so is it from and if i try always it going. committed to reducing our waste to almost zero we go back to a flood this year. this is the last place that you would expect to see a little poem a coach a garden going on in somebody's front room i just started this journey barely a year ago so a lot of things are to me a experiment you're here on your new experiment with all this how do you do you
kind of creating a network here because you can't be the only person saying yeah when i was suddenly gross on facebook it was sometimes frustrating because i seem to be the only person posting but now i think it's at least three thousand five hundred and it's quite surprising i think when we see in the regional taking just a small action to me is very encouraging because they start to take this. on the journey to zero waste community still have a long way to go last year singapore's five point five million population over seven point five million tons of waste that's one half tons per person but momentum is building and similar grassroots projects are sprouting up throughout the city. and she's invited us to come across town and have a look at her own community garden how are you. so this is your project
yet my neighbors who come and spend time here in the garden actually doing stuff direct. lawyers. at the moment the search for a home ever since soybeans grew before i feel that a lot of open spaces and sing up are should not be hard big challenges. it should be footscray and how can we surely make. maybe a fifty in the foot why does it need to just be a small one you know that it's only sosa few people in the community why not the larger community. over eighty percent of the food consumed in singapore is imported so the ministry of national development is investing heavily in boosting food production on the island of the range to meet jack and engineer turned food producer who's taking commercial scale urban farming to the next level. but i can't
say i've never seen a farm like this before i was in the world first in the world yeah i was here. for something that's never heard of a vertical farm i do description. sums up oil landscape so we don't have much of the land so of what use best of us singaporeans we stay in a has the effect is a spend to get it so look at why i guess they were because we're going to go over the thirty. system is using using what make it miss power so fun can go up get a. car now get a new transcend what so and the what the sim what the make it look i think is a sim what also give a dog a run and a what it will be a good one. so far you know to change the weather at all so far you know change the top west that's quite something given that this forms been operating for three years these rotating shows effectively increase the line surface area by
a factor of ten meaning this vertical farm can produce two tonnes of vegetables in a single day. king of the veggies it's a beauty isn't a look it's a weed that's the first we have seen in the in the entire place. this is to attract the pets is that and then their stand on these bars and then there's none in there i mean. the past many very good and even a past of the we catch em we are picked off fish. this is really so we're actually this is floating this is come this is yes company thought they completely fall in job why do you create a pool in reno in a pond we need a pond to keep out the far west they were so i do if you look back upon. our system so can we build upon a time we had a plan so why is assume it here we have one harvest of fish for every six harvests
of vegetables. the fish are feeding the vegetables and the vegetables. fish yeah so that the trimmings from the vegetables are actually going to feed the fish and using is a synthesizer line. yet. being located within the city these high density aquaponics set ups are also saving energy on transportation and storage so it's little wonder this guy the greens have gone and widespread interest wrote asia as well as with the singaporean government continue to support the development of the technology. to come back to the world of this is to learn more about their living building and what lies ahead for egypt's greenest city. this project for instance when it's fully grown will have eleven times the size area as green area so why go to all this extra effort to to swaddle your buildings in plants a huge one in a hot climate like singapore is the plants are the only thing that when the
sunlight falls on that they don't heat up they're actually take that energy and use it for the chemical processes of building carbohydrates and things so the calculation for singapore for instance is of before the city was built singapore was five degrees cooler. and all that heat ends up being converted into fossil fuel use as people use a conditioners to cool the space and throw even more heat out into the city if substantial plant cover even reduced singapore by two or three degrees celsius the energy saving for the entire country would be in the billions of dollars over the years a lot of the argument you have there or so much of the cities built you know it doesn't matter one of two buildings what difference can they my but if one building can. compensate for ten other sites not having any grain you can see that just by doing selective. injection of these kind of buildings through the city can already create a statistically significant amount of green in the city can you see the tension in
the future where you could. actually see some of this providing food because we know the singing for example reliant on food imports. we've sort of done generation one which is providing a lot of planting and achieving these plot ratios i think generation two is ok now we have this what can we do with it and that's why i think there's anything you do on land on the ground you can start thinking doesn't make sense to do that pile on of buildings of you know food we're also very interested in. you know can we make it not just decorative but can we make a very biologically productive we can like in our lifetime how many buildings can we build this is something that needs lots of people doing it and it needs rethinking at the planning level and the whole city visioning. so we've come up to the sky bill at dawson which is one of richard's public housing
projects and it does feel great i mean the planting design in this shady canopy of solar panels he was lovely but i mean looking out at the view it's pretty terrifying it's not just the density but it's the number of housing in and building development projects and it's this kind of a model of oil tankers and shipping containers that stretches to the horizon in almost every direction. but when you start to look at that horizon through richard's eyes and you see the potential for a rooftop aquaponics vertical forest you know you start to have hope but for us to make that future a reality then it means getting the grass roots in gage's it means the choice fair . me and all those guys get things going from the ground up and it means they're missing the planners in the policymakers halfway if we're going to see cities that are truly sustainable. as on the chopper he says continue to
expand we're being pushed to explore more radical solutions to the environmental cost city living in taiwan a french architecture firm is constructing a garden tower which will absorb one hundred thirty tons of carbon dioxide each year. while local government in washington d.c. is utilizing a high foothold in the city center to generate energy kinetically for lighting using a technology called pay. and a south korea some dough has been dubbed the smartest city on the planet developed as a built the world's largest pneumatic waste collection system citywide recycling is projected to reach seventy six percent by twenty twenty innovations of that if the support and funding to adopt the widely is a chance the world's much openness is could become sustainable and has so many of us living in cities the environmental impact could be huge.
