Hemp holds the key to a sustainable future | Amy Ansel | TEDxSeattle



The Hemp plant — marijuana’s sober cousin — is poised to revolutionize industry by taking the place of more toxic materials and putting us on a path to a …

  1. No it is not carbon neutral there is greater carbon footprint to make paper pulp out of hemp than trees. There are extensive studies for it. Also paper is neither better nor stronger, nor cheaper. It becomes 5 times more expensive actually

  2. I am ashamed both as a stoner and a science fiction writer that this video does not have any more views.
    I paint with watercolors, I can use hemp paper.
    We can change our building material to hempcrete.
    We can build stronger plastics with hemp.
    We can build our reactors with hempcrete on top of houses.

    Like, the potential for a single plant is astounding. And yes there is far more options you can use for hemp, I am literally scratching just the surface.

    This video needs 7 billion views if you ask me.

  3. As soon as I heard the word SEATTLE, I know that they wouldn't talk about the uses of HEMP without first attacking everything else. Hemp is great, but it is not a replaement for all things. Plastic does not last 200 years, it degrades just like everything else. You want to talk about polution look at solar panels, that create more pollution per kwh than nuclear energy, but no mention is made of that.

  4. Amy talks with passion. It was motivating to hear. There are just a few factual errors. Hemp and marijuana are the same species, (Cannabis sativa) but a different variety. There is no equivalent of 'cousin' in the plant world. Amy mentions every part of the plant can be used but doesn't mention what roots can be used for. Importantly hempcrete is not load supporting like concrete. It is used as a solid wall for insulation and humidity control. Hempcrete can be used as insulation under floors but not as flooring. Good on her for getting up in front of such a large audience, the world needs more people like her.

  5. Some people and some companies are trying to separate hemp from cannabis.. they are the same plant, in the past we use male cannabis for fiber and female for flower… now they are saying that hemp "is the cousin of cannabis…" The Emperor Wears No Clothes explains it all

  6. Careful about investing in the (pot and hemp) companies promoted by the two older white brothers with a clown cap logo. They sell investing into mega farm machines that spray out tons of pesticide every hour. Best Wishes to All for 2020

  7. I am a hemp leader and it is my business and I am pleased with this presentation. I should say that hemp is not easy to grow or harvest and it does require pesticides. This year we were surprised by the insects that attacked our hemp. Corn borers, caterpillars and mites are just a few that like hemp. They are working on organic rated pesticides now. It is untrue that insects don't like hemp. As far as bioplastics, we must continue to do research but we are not there yet. Hemp is used in composite materials, but they have not yet created a true compostable hemp bio-plastic. Right now it must be mixed with some other material to have any shelf life and needs a catalyst material to compost. But research will get us there if we have the time and the commitment to get there. We all must fight for the right for hemp to be the industrial crop that we need to save the earth. Big Ag and Big Pharma are trying to take over the hemp market now. We must keep an eye on the bills our legislators are trying to pass under the radar. We all need to pay attention and take part in our State Governmental process. Most of these legislators are uneducated and do not understand what they are voting on. We need to educate them and get these laws passed correctly and protect the small farmers.

  8. It's not all roses. The ability of hemp to replace oil based plastics is greatly exaggerated. Take hempcrete for example. It cost about $10.00 per cubic foot and has an R value of 2.5 (1 = 2.5). That is not all that great. It's significantly more expensive than traditional building techniques. Maybe using Hemp products will get cheaper but that is doubtful because working with hemp requires significant labor and energy. At least if it is deregulated entrepreneurs can experiment and perhaps find new things that are truly revolutionary. Exaggeration is not being helpful. I would prefer the argument that the government should get out of the way and let market forces operate unless there is clear and present danger to the public. That is the real argument.

  9. The inability to degrade is useful for some situations such as seals, and medical devices. I feel this need will not go away. I do agree that bioplastics and more sustainable methods of production are the future, but plastics will still be needed, just in sustainable forms.

    However if feel that reformed cellulose (Rayon) would be an arguably better fabric. Then for petrolium products, I feel that PLA, and Standard petrolium products made from pyrolysis oil, or HTL produced "bio-crude" oil.

    I feel that large scale production of anything produced will produce waste, so i feel changing the source of material would not remove this issue, this must be done by waste managment technologies.

    Also the issue with plastics is the source material mentioned above, recycling is more of a solution. Even if it is still bioplastic, it still must be disposed of properly, preferably via recycling.

    Finally for structual applications i feel like bamboo composites, reformed cellulose composites, or carbon compositeswould all be better solutions. (For instance bamboo chipboard, reformed cellulose matting for reinforced sustainably produced concrete, or carbon fiber composwite shells for vehicles etc)

    This is not to say that hemp couldn't be one of the feedstocks, but it isn't the wondermaterial to replace all.

  10. Makes sense to use hemp instead of corn for bio fuels,why import crude oil when you could grow your own,no more wealth going out of the country.Stop growing tobacco grow hemp instead,big oil won't like it they need to get involved in alternatives.
