Hello, for my thesis Exploring the end of life possibilities of mycelium composites I will research the biodegradation of mycelium composites.
Due to lack of apparature, a low-tech test will be applied: soil burial test. Before posting all my work, I will write down the methodology I will apply.
- First test samples are approximately 50x50x25mm (bxlxh)
- Place all samples (5) in one container (plastic box) or buy seperate containers (ceramic flower pots)
- Weigh the samples. It is assumed that the weight of the samples are their dry weight
- Fill the containers with soil (universal soil used for indoor plants). Cover the sample with 10 cm above and under the samples
- Cover the containers with plastic foil, and daily maintain the pH of the soil to 7 and regulate the soil moisture
- Each week the samples will be retrieved, rinsed under destilled water, measured (bxlxh) and placed in an oven for 24-48h at 50-60°C to obtain the dry weight.
- samples are weighted and IR-analysis will be apllied.
This methodology is based on other papers where soil burial test have been applied to plastic. Therefore, in this methodology some question marks remain:
- What is the ideal moisture content of the soil that should be regulated?
- How long should the sample remain in the oven to obtain a dry weight?
I will update this post, when I have initiated the tests. In the meantime, I am searching for more information and equipment.
