Abstract[edit | edit source]
Background[edit | edit source]
Criteria[edit | edit source]
|Accessibility||System should be easily built and used by anyone in the household. It also should be hassle free to clean, turn and move around the yard.|
|Functionality||Able to take in compost from a home that cooks often so has plenty of food scraps as well as garden and lawn waste. Stands up to midwest climate. Keeps food scraps away from deer and squirrels.|
|Appropriate||Use materials that were around the house as a quick daytime project and also materials that would otherwise be considered waste. Minimizes cost.|
|Move-ablitiy||This system is not needed to last a long time but rather should be able to be deconstructed quickly in case of winter storms or discontinuing the project.|

Schedule[edit | edit source]
- Turning compost (3-7 days/week)
- Adding food scraps and browns (carbon materials) as needed
- Checking temperature and moisture
- When enough compost has accumulated, stop adding food scraps and continue turning and monitoring temperature and ratios.
- Harvest finished compost
- Possible cleaning of bins
- Cleaning of bins
Troubleshooting[edit | edit source]
From the first design to the second, these were some adjustments I made. I also made a flow chat to help figure out what is wrong with your compost and how to fix it.
|Compost not decomposing||compost not heating, add insulation in first bin|
|Compost is smelly||add holes for aeration, be sure carbon to nitrogen ratios are good.|
|Animals getting into the bin||secure with bungee cords, if smaller pests like rats are your problem look into purchasing vermin mesh and enclosing system in that.|

Conclusion[edit | edit source]
An at home composting system is achievable for just about anybody who has the desire. With trial and error of what works best for you, it can be easy to create a compost system that is tailored to your climate and needs.
