## Pyrolysis Operation with Mr. Peter Burgess 

### Objective
Learn enough information to create a business plan related to setting a Pyrolysis machine.

### Questions
1. Introduce ourselves (20s)
    1. Chuan, software engineering student 
    2. Judy, mechanical engineering student
    3. Could we record this meeting?
2. Provide some context to the project (40s)
    1. Our project is about turning the 25,000 tonne annual post harvest wastes located at HVP plantation at the border of VIC and NSW into a useful resource. 
3. Could you explain to us how what is the ECH02 system currently running at Hello-Fresh? What is produced and how are they consumed?
7. What's the input to output ratio? Pyrocal company converts 750kg/h of biomass to about 90kg/h of char.
8. How do you prepare and store feedstocks?
6. Could you walk us through the process of setting up, running, and recycle a pyrolysis machine? 
10. What infrastructures are necessary for the success of a pyrolysis system?
11. Is the market demanding renewing energy from Pyrolysis? Could we be producing more than we can consume?

## Project context




## Rowan interview
1. Expain the aim "to understand the Burton engine"
2. How does an engine gets transported and setup?
    3. EP have just started building commerial engine
    4. 20 foot container or 40 foot container
    5. Setup heat capture site, install a heat exchanger which is dependent on 
    6. The working fluid in Barton engine is air which allows easy installation compared to other forms of working fluid
    7. A site for container
    8. 3 phases of power
        10. Heat capture system, 30-40k, the whole process of capture 
        11. Engine 
        12. Isolation transformer that doesn't change the voltage but instead act as a protector to the grid
        13. Paper work to connect the power point to grid, 10k
3. Operator and maintainer training for the heat connection
4. The Burton engine converts heat to electricity
5. 100kw in 20 foot container, 200kw in 40 foot container
6. Min 450C heat from source has a 30% efficiency to drop to 300C, 300C is removed from stack
7. Internal compustion engine such as Burton is very efficient. 30% efficiency is similar to car's engine
8. Hydrolic oil and lubricant oil will be used
9. Mark 2 engine in a 24 foot container with heat exchanger will be 12 tonnes, 6 tonne without the heat exchanger
10. Not registered with climate solution fund because CP hasn't generated carbon credits
11. Estimate 20 years life expectency because the use of air as a working fuild allows the engine to be clean. Only the heat is consumed.

Are there anything you expected us to ask but we didn't ask?
We should have expained our background so Rowan knows how much explaination is needed

## Summary
There are few path for wood wastage
* Energy

Current process of burning post-harvest residues 
* release carbon

## Research

### Biofuel

### Biochar
* https://www.agriculture.gov.au/ag-farm-food/climatechange/australias-farming-future/biochar
* https://en.wikipedia.org/wiki/Biochar

* Biochar is the solid material obtained from the termochemical conversion of biomass in an oxygen-limited environment. The burning of wood in a campfire can yeild biochar but is less efficient compared to a pyrolysis machine.
* Biochar in soil reduces the rate of CO2 emission from soil, because the carbon stored in biochar doesn't decompose to CO2 for thousands of years.
* Improper production process can cause Biochar may contain heavy metal and toxic organic compounds, however
* Biochar improves yeild for certain crops by
    * reduce leacching of E-coli
    * increase soil moisture
    * provide a habitat for soil micro organisms
    * elevate pH
* The porous nature increases the retaination of water and water soluble nutrients, and on the other hand also absorbs pesticides and herbicides leading to poor weed control. 
* There are different types of biochars as well. Grass or crop–derived biochars appear to have the best balance of agricultural benefit and carbon stability. Wood–derived biochars were more carbon rich, whereas biochars from manures and food wastes recorded higher nitrogen and phosphorus levels.
* The effect of biochar to soil also depends on the soil quality

[Can biochar help save the world? (1)](https://chinadialogue.net/en/climate/2836-can-biochar-help-save-the-world-1/)
* The carbon in biochar is mineralised, so it's very resistant to breaking down.
* Byproducts of biochar's manufacture are very attractive, address three or four critical crises at once: The climate-change crisis, the energy crisis, the food and water crisis (biochar fertilises soil and retains water)
* The natural carbon cycle can only remove about 54% of the carbon that produced by human activity
* Ways of manufacturing biochar
    * centralised
    * decentralised: manufactured by individuals or a small group of individuals
    * mobile: vehicle equipped with a pyrolyser (powered by syngas) visits farms distributing biochar while collecting bio-oil to be transported to a refinery and turn into liquid biofuel for vehicles. (Brazil's sugar cane industry)
* Crucible Carbon predicts carbon sequestration from biochar at the cost of $20 a tonne.
