Spent mushroom substrate and sawdust to produce mycelium-based thermal insulation composites (2024)

FAQs

What is the composition of spent mushroom substrate? ›

Spent mushroom compost (SMC) is the substrate remaining after mushroom production, with approximately 5 kg of SMC produced for each kg of mushrooms. Mushroom compost is a mixture of 60 to 70% straw, 28 to 34% poultry litter, and 2 to 4.5% gypsum. It is made in a series of stages, termed phases.

What is the thermal insulation of mycelium? ›

As a result, the literature review indicates that mycelium exhibits exceptional thermal and acoustic insulation properties owing to its low thermal conductivity, favorable water absorption coefficient, porous structure, and considerable mechanical strength.

What are mycelium bound composites? ›

Mycelium-bound materials are composites made using a living organism, a fungus, growing onto a nutrient-rich substrate, typically plant-based, such as straw, sawdust, cotton, etc.

What can I do with old mushroom substrate? ›

Obtaining spent substrate in the fall and winter, allowing it to weather, will make it ready to use in a garden the following spring. Spring and summer are the best time to use weathered material as a mulch. As a soil amendment, spent substrate adds organic matter and structure to the soil.

What are the benefits of spent mushroom substrate? ›

Spent mushroom substrate (sometimes called mushroom soil, recycled mushroom compost, or mushroom compost) can improve the structure of clay soils, reduce surface crusting and compaction, promote drainage, increase microbial activity, and provide nutrients to turfgrasses.

What are the disadvantages of mycelium insulation? ›

While it does offer several benefits, there are also some drawbacks and limitations to consider: 1. Limited Mechanical Strength: Mycelium-based materials generally have lower mechanical strength compared to traditional construction materials like concrete, steel, or even wood.

How durable is mycelium insulation? ›

Durability. Mycelium products are at least as durable as most conventional construction materials. They maintain their insulative properties throughout their life.

What are the benefits of mycelium insulation? ›

Mycelium-based materials are biodegradable, consume little energy and have a low carbon footprint. They're also relatively cheap and offer good fire, thermal and acoustic insulation.

How do you make mycelium composite? ›

First the substrate needs to be sterilized and inoculated with fungal spawn (mycelium) to achieve the initial growth. After the initial growth (one week period), the composite is moulded into the desired shape. The composite is grown for another week period before being dried.

Why is it easy to grow mycelium composites? ›

When two or more hyphae are fused together, a large network can be formed and it allows for more nutrient transportation between the substrate through the large network; as a result, mycelium can grow fast, strong, and dense. These two hyphae structures make Basidiomycota unique in biomaterial production.

What is the difference between mycelium and substrate? ›

To put it simply, a substrate is a bulk material that the mushroom mycelium can use for energy and nutrition. A good substrate is required in order for the mushroom to grow and to fruit.

What is the physicochemical composition of spent oyster mushroom substrate? ›

Spent oyster mushroom substrates

The SFMS was prepared by mixing softwood sawdust, rice bran, and lime with the ratio of 100:10:1, respectively.

What nutrients are in spent mushroom compost? ›

Spent mushroom compost contains about 1-2% nitrogen, 0.2% phosphorus and 1.3% potassium. After being aged for 18 months, phosphorus and nitrogen do not change, but potassium can decrease.

What is the NPK of spent mushroom compost? ›

Fertilizer Salts in Mushroom Compost

The average NPK of mushroom compost, in the above study, was 1.1-0.7-1.3. This is well within the range of other types of compost which tend to be around 1-1-1.

What is the carbon to nitrogen ratio of spent mushroom substrate? ›

The average pH of mushroom compost is 6.6 (6.0 to 7.0 is an ideal range for most plants). The amount of carbon relative to nitrogen is an important indicator of nitrogen availability for plant growth, and an ideal compost should have a ratio of 30:1 or lower.
