    Very good material, friendly and easily to understand. This is an eye opener to me

    This was a refresher course for the knowledge i have on bioenergy great work.

    Very interesting read. With all of this conversion of waste material, is it possible to go back to where there are mass waste storage areas (landfills) and basically use this old waste up to a digester and produce energy? Any comments are welcomed!

      Hello Liz,

      Good day to you. In response to your question, I reply is an absolute ‘Yes’ provided you follow the processes outline in the video and using the appropriate equipment (digester) required to produce energy for your village, community, city or country.

      No doubt, the Video on Bioenergy Resources and Technologies by Mr. Miguel Franco was highly insightful and informative to participants on this MOOC.

      Finally, I suggest you pay attention to the rich materials provided in this Reader 3. Goodluck with designing your new digester system for energy production.

      Regards,

      Anthony Madume

      Almost all landfills are working as anaerobic digesters. Each second worldwide landfills emits thousands m3 of biogas. The problem is to catch the produced biogas. The technology is quite simple but preferable use since the beginning of landfill usage: Membrane, waste, membrane and a gas pipe.

      Last week I visited a landfill in Melbourne, Australia where this was being done via vertical extractors. It is quite a developed process as it is economically viable to sell the electricity onto the grid. Constant surveillance of the landfill is maintained for “escaping” gas where the cover needs maintenance. A balance is maintained across the landfill to prevent the gas from building up using manifolds against quality of the gas.

    The basics of bio-energy is well explained in this material.Thank you

    Very interesting and easy to digest, “waste can be converted into something useful”

    Amazing materials preparation and presentations. It’s wonderful

    Is someone familiar with the use of biogas as a vehicle fuel? I thought that this is not an environmental friendly process since a lot of rain forest is cut down to provide space for the growing of soy, rapeseed etc. Can someone give me a little bit more insight into this topic?

      I am not so familiar with the use of bio-gas as a vehicle fuel, but as far as i know and from the information we have read in this chapter, one does not have to cut down trees to grow the energy crops purposely for the bio-fuel. the plant, crop or food residues (wastes) are what make the field an interesting venture and sustainable. therefore someone would have maybe to grow the crops then target their wastes.

      in addition, if your next confusion is about the emissions from such fuels, then remember such fuels are from biomass sources, the gases that they emit like carbon-dioxide are part of the natural carbon cycle, therefore would be utilized by plants in the environment for photosynthesis, and the process goes on and on.

      Please let me know if i have been of any help or i have made things more complicated! and i hope someone else can jump in to provide any more explanations that can be of valuable help in this.

      Well, for instance, biofuel is not only from plant or crop residues, it is also from oil used when cooking. There are many examples around the world where countries like Spain uses this oil to produce biofuel.

      To use biogas as vehicle fuel it has to be upgraded to biomethane (same as methane or CNG). Minor adjustment has to be done to a spark plug vehicles. There is 22.7 million methane powered vehicles worldwide (2015).
      Soy, rapeseed – are used to produce bioDiesel.
      Biogas is produced mostly from waste (agricultural, municipal etc.), energy crops, manure.

    this has been my best reader, very informative

    I’d like to learn more about hemp production for BioEnergy. What are some of the laws regarding hemp growth in YOUR country?

    These different aspects of BioEnergy are incredibly fascinating. I’ve known about the anaerobic digesters for a couple of years now, but didn’t know much else beyond that.
    Why is this so fascinating, you ask?
    Well, I hope to someday live completely off the grid. I would love to have multiple sources of electricity and heat in case one system fails or works better in different parts of the year.
    After this MOOC is over, I look forward to doing more research.

    Can’t wait to read the material.. Busy week

    Dr Miguel Franco’s lecture is quite ispiring for the simple reason that it exposed the business potentials that participants may key into. The course (generally) gets more interesting but challenging each week.

    I don’t know why Sarah E wants to go into hemp production. If you’re so keen about it, don’t worry too much, large hemp farms are here but you must be ready to face the law. contact me then

    I am really enjoying this program thank you for putting this together

    It is true that the main challenges in adoption of bioenergy especially at a small scale level is the high cost of installation and inadequate technical expertise. Initiatives such as community training and skills transfer as well as formation of self help groups which can help in mobilizing funds are possible ways in which this can be addressed. That was an interesting reading.

    i anticipate new revelation. learning new things

    I call attention to the use of biofuels (its benefits were far for me), it is incredible that from available raw materials such as manure, food waste, crop residues, and wastewater and many different will improve increase the quality of life for the world’s poor living in rural areas, and to reduce greenhouse gases.
    This shows the potential we have in developing countries .. Hard work awaits us yet!
    P.S. I enjoyed this chapter! thank you
