      Re poop power this process sounds a lot like thermal depolymerization which function similarly by breaking down organ and inorganic polymers into simpler compounds using high temp steam and pressure. Is there a difference in these two processes?

    There they
    - first use huge heat pumps to utilize the thermal energy of the waste water and send it to the district heating network
    - treat the sewage
    - use the sewage sludge to produce biogas
    - use the biogas to produce electricity and heat (which, again, goes to the district heating network)
    - the remaining solids go to a power station where they, again, produce electricity and heat, which, again, .....

      Yes. You could expand the chain even more. It is likely that the process just reached its degree of economic viability. For instance, at step 2, you could add a biodigester with anaerobic bacteria to produce methane AND heat for your city. I see that as your step 3, but you could bump it back with better filters and a little more power. You will also see that with sufficient gas and steam, you can do hydrogen production at a very low cost. If you separate your slurry after your step 3, you can send some off for fertilizers and keep some solids to be desiccated and then incinerated.
      There are many "feedstocks" produced by humans and with food production that can be used efficiently.

      actually the energy to dry the final sewerage mass to something that can be burned pretty much wipes out any actual return, but such an integrated system does minimize use of carbon based fuel to treat sewerage. this technique improves on that somewhat and further refined might generate more energy than it uses. given it's never gotten big gov't support in US, or anywhere, like solar, wind, bio diesel from oil sees, and ethanol from corn and sugar, we will probably never know how good the system is.

    Hi Matt, great video. I've worked for a few years in Environmental Engineering (drinking and wastewater treatment). It doesn't really surprise me that this is having so much trouble making headway. In my region (Northern CA), many of the WWTPs are up for total replacement and the smaller ones tend to be from communities with small budgets that often don't get very much funding. Government spending will usually only cover 80% of replacement costs unless the average median income of the area is much less than the state's average.
    Even turning wastewater into fertilizer is extremely expensive and a city has to have a really big budget to consider it. This is a great idea, but unless the state and federal governments are convinced of the usefulness of this idea and the money that can be saved, this unfortunately will not make much headway. The only loophole I see is if a large city (like Sacramento, SF, or LA) gets wind of this idea and decides to implement it and is successful.

    • @ocaeocae
      @ocaeocae Год назад +2

      This is the first I've heard of HTC, but I am pretty familiar with anaerobic digestion, which seems to provide most of the same benefits - but perhaps isn't as costly? When I last looked into it, the amortization of the investment in AD was something like 10-15 years (don't quote me on that). On a very small scale, this is what is used in rural areas of developing countries with very basic technology (i.e., essentially two drums, and a tube leading to a cooking stove where the gas can be burned off). It's absurd to me that this isn't common practice in the US... such a missed opportunity.

It takes the sewage of 2-3 people to make a cup of coffee from the methane.

    Hey Matt, you should check out the biogas toilet system. I was looking into it for my tiny house and it goes right along with this video series. Human waste is pumped from the toilet to a thick black bag with weights on it. Methane production builds against the pressure of the weights and there is a low-pressure gas line that feeds to a burner system in the kitchen where you can cook your food from farts. On the backside of the bag, there is a poop chute for adding kitchen scraps and such, as well as a spigot for collecting the nutrient-rich poop juice for feeding plants. It's a win-win for people who want to start small, and not have to dig a septic tank.

      @@michaelchildish Michael, I personally am a bit skeptical about BIO fuels. This video on poop to fuel is the only option I have seen that seems scalable, is potentially less harmful to the environment and addresses not only the problem of what to do with poop but also where to get fuel. It's unfortunate that we need to burn the product in order to get the energy out of it because that will likely just perpetuate the problems we are currently creating by burning fossil fuels. I checked out a report on ecotricity's grass to gas and noted the following "Harvest naturally occurring grasses from land previously used for grazing livestock and lower quality arable farmland, creating new wildflower meadows in the process, so increasing biodiversity and providing environmental benefits at the same time." So first off they are evicting a food source in order to make energy. That sounds a lot like the highly, highly, subsidized ethanol industry in North America which has displaced significant food growing lands for more profitable fuel agriculture. And while the second part re increasing biodiversity sounds good I am sure that the plants, animal, insects etc that inhabit those new meadows are not overly appreciative of the machines that show up on a semi regular basis to harvest their temporary homes. There is no easy answer but I do think this Poop to gas option is the most promising BIO fuel solution I have ever seen. Finding a way to get energy out of the fuel without having to burn it (or burning without any unpleasant additional outputs - without having to use the majority of the energy to clean up the outputs!) would make this a truly world changing solution.

    I've been working in wastewater in Cincinnati for a few months now, and one of the things that always gets shown off when at one of our WWTPs is that there is a room with a few old generators, which were decommissioned probably a decade ago. They used to run on natural gas produced as a byproduct of breaking down solid sewage waste, which sounds pretty great, but had some downsides. Namely, when you assume that all of your solid waste is carbon, oxygen, hydrogen, and nitrogen, then the chemistry works fine, but sadly people poop other stuff sometimes, and that complicates the natural gas production process, and the resulting natural gas is full of a lot of contaminants. When we ran it in the generators, it was really inefficient and would pretty consistently clog the generators with soot. Eventually we stopped using the generators and went to just incinerating the waste, which from an environmental standpoint is less than ideal, but we have been looking into possibly reusing the ash from the incinerator (which is a really cool rust color) in concrete and bricks.

    I work in the industry. We have a treatment plant that burns the methane that is released from the waste solids digesters. The methane is collected and goes through a super cooling system that drops the water vapor out of it and then we burn it through basically diesel electric generators that can run it. About half of the treatment plants systems can be powered when those generators are online. The local military base also uses our effluent line for heating and cooling. Its used in the same manner as geothermal. We are now also producing class A solids that can be used in fertilization for crops for human consumption. The waste is collected and put into giant vacuum chambers. A vacuum is pulled in the chamber then super high pressure steam is injected into the chamber.

    As a wastewater operator myself, I am very interested to see how this develops, the three main concerns that jump to my mind are.
    1 Scalability
    2 Sustainability
    3 Cost effective/ROI
    Looks awesome in principal.
    I work at an activated sludge plant (basically natural decay process on steroids). for years we were able to spread our biosolids (which were VERY stable, they literally look like dirt), on our hayfields. It was great, low cost, increased crop yields, very convenient, very safe. then some dope on the local assembly (who knows NOTHING about waste treatment) read some California paper on poor biosolids agricultural applications and convinced our local government to cancel all the spreading permits, So now we have to truck those biosolids 40 miles twice a week to the local landfill, where they buried at a premium hazardous waste charge (at taxpayer expense remember), right along with the domestic trash disposal.

      1. Each HTC Train will process between 15,000 and 20,000 wet tons of biosolids per year depending on solids % and flow rate (eq. to the population of 100,000 people.) multiple trains can be set up to run in parallel for scalability. excess capacity can be filled with other wet organic waste sources i.e. food waste, manure, green waste earning additional revenue.
      2. HTC reduces GHG emission by over 85% compared to waste activated sludge and land application processes. HTC reduces biosolids volume by 75%, so even if continuing to land apply there would be significant savings..
      3. HTC has a levelized cost of transformation (LCOT) of $32/wet ton. Your ROI would depend on the savings of current disposal cost in excess of $32/ton. Most municipalities see a positive ROI in year 4-8 of operation.

      Great question, what I know personally is that the use of alternative fuels in biomass furnaces are regulated in Europe and many of these alternatives produce high values of nitrous oxides, VOC's and Ammonia. Whether that pushes the emissions past the NOx limits I'm unsure but definitely an interesting question.

    • @aleenaprasannan2146
      @aleenaprasannan2146 2 года назад +2

      The comparison should actually be between normal sewage emission and using it this way instead. Normally the emissions would be high in methane, however after processing or digesting biowaste, or just burning the methane as fuel aka methane to carbondioxide, it's four times better. Methane is a four times worse than carbondioxide in causing global warming. If you inoculate nitrous oxide respiring microbes in the digestor, then you are fixing a gas 300 times worse than carbondioxide

    When it comes to recycling, people don't realize how far they can go. Stuff as simple as your own body hair or fingernails can be reused within the environment. For humans' hair, it mainly helps out plants by granting the plants a supply of magnesium, which basically acts as a form of "stamina" for the plants to complete certain processes of growth. As for your own pet doggies or cats, their hair is rich with nitrogen that can be extremely valuable for plants because it will capture moisture and help the plants maintain their desired "body-temperature." As for fingernails, they essentially act as a "meal" for the microorganisms within the plants, which will take longer to break down rather than hair but is truly really valued to those plants. I can go on and on with how far recycling can be taken, but it's a matter of how much effort people are willing to put out, pulling their own weight.

What's left is then landfilled but doesn't give off methane and if relatively safe to dispose of.

    1:34 Ah, but I work in water/wastewater treatment for a living, so I do :) From what I've seen, the majority of dried sludge from plants I've worked with goes towards fertilizing non-food crops, but I'd really like to see the economics of HTC in detail. It seems like a promising technology!

      It looked like it was put on silage crops for cows which got into the milk.

    Good job on all the #2 references ! I've been reading about this whole cycle - one thing I don't quite understand is how heavy metals resolve...

      Also, regarding breaking he C-F bonds in PFAS, what happens to the fluorine? It doesn’t just disappear.

      Yes, where do the heavy metals end up? If in the biochar, then will they leach out?

    Great video! It’s so hard to find information on this topic. Two questions for anyone that knows the answer(s).
    1. Why must sewage be treated prior to being used as fertilizer? I get the PFAS argument but does bacteria get absorbed by the roots and end up in what we eat?
    2. When you burn waste how much (if any) of the nutrients in the waste go up in flames as well?
    Thanks!

    Sounds great, but does this not "steal" nutrients from the environment, the fields that we grow crop on, thus the food we use? Wouldn't this mean that we need to use up more resources from nature to feed/clothe/shelter humanity, thus contributing more to emissions too? Genuine question :)
