Toyota Develops New Flower Species To Reduce Pollution

teko_teko writes "Toyota has created two flower species that absorb nitrogen oxides and take heat out of the atmosphere. The flowers, derivatives of the cherry sage plant and the gardenia, were specially developed for the grounds of Toyota's Prius plant in Toyota City, Japan. The sage derivative's leaves have unique characteristics that absorb harmful gases, while the gardenia's leaves create water vapour in the air, reducing the surface temperature of the factory surrounds and, therefore, reducing the energy needed for cooling, in turn producing less carbon dioxide."

    That's great but it may be a surprise to some people to learn that cherry sages do eventually die, and decompose and thus re-release that which they have absorbed.

    Carbon offset, one of the greatest scams in history. Pay us to plant some trees, which we can later cut down and sell.

      Not really. That's where coal came from. Plants inhale the carbon dioxide in the air, make 'em carbom, die, decompose, get buried in the ground, and 100,000,000 years later become coal and oil.

      Only in places experiencing significant subsidence (think of the Mississippi delta), where plant materials at the surface will eventually be deeply buried. The fraction of plant material that does ultimately get buried for the long term is minuscule compared to the amount that gets promptly recycled by decay processes, right back into the atmosphere. The chances the scenario you describe is happening at the site of a Toyota plant are small indeed unless it is built on a subsiding swamp.

      The part I don't get is "while the gardenia's leaves create water vapour in the air" What? Don't ALL plants produce water vapour in the air?

      Planting *any* plant would have the rather minor effects they describe. Getting rid of a lawn and allowing a genuine forest to grow might have a net positive effect, but only to a limited degree (as it grows). It's a fluff piece. The only thing innovative here is their public relations department.

      Close. Most coal came from the Carboniferous period where there was an explosion of plants, many of them in boggy areas. When plants die in bogs they fall in the water and bacteria can NOT decompose them. This is why the carbon was sequestered and turned into coal.
      Today, there is very little chance of this happening, especially at a plant in Japan. In all likelihood these flowers will decompose when they die and release all their nitrogen oxides back to the environment.

      Plants may produce coal, but I have it on good authority that oil comes from dinosaurs:

      First the Earth cooled...and then the dinosaurs came...but they got too big and fat...so they all died and they turned into oil...and then the Arabs came...and they bought Mercedes Benz's...and Prince Charles started wearing all of Lady Di's clothes...I couldn't believe it...he took her best summer dress out of the closet and put it on and went to town....

      Wouldn't the nitrates in the soil act as a fertilizer for plants, as opposed to leaving it floating in the air for humans to breathe in?

      Both. Some bacteria make ammonium from nitrogen, which keeps it in the soil. Others dump it in the air as N(2) and N(2)O. Local conditions limit how much gets mineralized into ammonium naturally. If there's enough oxygen around, other bacteria make it into nitrates, which then feed more plants. I reckon if they're planted sparsely, removed regularly (and composted properly), or rotated with nitrate-hungry plants, quite a lot would stay in the dirt. So, yeah, fertilizer and stuff, although some nitrogen is gonna float away no matter what.

      Actually the buildup of soil is in direct contradiction with your assertion that the majority of the carbon is re-released into the atmosphere. A good example of this process in action is right here where I live along the Great Lakes, the last glacial period ended only 12,000 years ago and as the glaciers retreated they completely scoured the bedrock yet today there are feet and feet of soil built up.

  2. Bad reporting by AxeTheMax · · Score: 5, Informative

    Lots of bad science reporting there, just what you would expect from a motor journalist talking about botany. New species??? All plants absorb gases, including any nitrogen compounds in the air. Any nitrous oxides would be absorbed within the leaf, since they are nutrients and plants have an ability to absorb nutrients through the leaves (foliar feeding). All plants give off water vapour. I suspect most trees would be better at cooling the factory surrounds than gardenia plants, since by their size and nature they are faster growers and thus can transpire more water, and (for most species) they have more leaf area per unit of ground area.

    Your clever plan has one slight flaw, namely that Toyota is not the only company on the planet making cars. If they stop then people will just buy cars from elsewhere that are probably less environmentally friendly, resulting in more pollution overall.

    You are correct. However, the article talks about nitrogen oxides, not molecular nitrogen. The nitrogen in nitrogen oxides is already "fixed" and can be absorbed by many different kinds of plants.

    Why do you think you put nitrogen fertilizers to plants, if the atmosphere is > 70% nitrogen?

    It is a load of shameless and deceptive nonsense; and does make it better that it is wrapped up in florid language, if you will excuse the pun, hur, hur. "Create a new species"? Even highly educated plant breeders haven't been able to do that, but a car manufacturer manages to do it with a gesture and a lorry-load of hype?

    For a plant species to work well as carbon-capturer, it ought to grow fast (thus producing large quantities of biomass) and it should break down slowly, so the CO2 isn't released quickly again. Gardenias and sages don't really fit the bill - grasses might, some trees might and green algae, perhaps. But I understand, of course - surrounding the offices with a few hectares of slimy ponds isn't as pretty.
