Inspiration
Plastic pollution is one of the most pressing environmental issues today. Witnessing the increasing amount of plastic waste in our surroundings and the ocean, we were inspired to find a sustainable solution. The innovative idea of using fungi, known for their incredible natural decomposing abilities, sparked our curiosity. The potential to turn a major pollutant into harmless byproducts through nature's own decomposers motivated us to dive into this project.
What it does
Our project leverages fungi to sustainably break down plastic waste. Here's what it does:
Cultivation of Fungi: We cultivate specific fungi species known for their plastic-degrading abilities.
Plastic Treatment: The plastic waste is pre-treated with UV light to enhance degradation.
Enzymatic Breakdown: The fungi secrete enzymes that break down the plastic into smaller, non-toxic compounds.
Decomposition: Over time, the plastic waste is significantly reduced and decomposed into environmentally friendly byproducts.
The project offers an eco-friendly solution to plastic pollution, promoting a circular economy through sustainable waste management. It's an innovative approach to addressing the growing plastic crisis and reducing environmental impact
How we built it
Research and Selection: We started by researching various fungi species known for their plastic-degrading abilities. We selected Aspergillus terreus and Engyodontium album due to their proven effectiveness.
Cultivation: Next, we cultivated these fungi in controlled environments, using agricultural waste as substrates. We monitored and optimized conditions such as temperature, humidity, and nutrient levels to promote healthy fungal growth.
Plastic Treatment: We pre-treated plastic waste with UV light to make it more susceptible to enzymatic breakdown. Then, we introduced the cultivated fungi to the plastic waste in specially designed bioreactors.
Enzymatic Breakdown: The fungi secreted enzymes like cutinase and lipase, which started breaking down the plastic polymers into smaller molecules. We closely monitored the process, taking regular samples to analyze the degradation progress.
Decomposition and Analysis: Over time, the plastic waste significantly reduced in size, breaking down into harmless compounds. We performed chemical analyses to ensure the byproducts were non-toxic and environmentally friendly.
Challenges we ran into
One of the main challenges was optimizing the growth conditions for the fungi. Different fungi species required specific environmental conditions, which involved a lot of trial and error. We also faced difficulties in scaling up the process from the lab to larger bioreactors while maintaining efficiency. Additionally, ensuring the complete breakdown of plastic into non-toxic compounds required extensive testing and validation.
Accomplishments that we're proud of
No accomplishments we are still on trial phase as it takes months to show response
What we learned
Fungal Capabilities: We gained a deep understanding of how certain fungi, such as Aspergillus terreus and Engyodontium album, are capable of breaking down plastic polymers. Their enzymatic processes, particularly those involving cutinase and lipase, proved to be incredibly effective at decomposing plastic waste.
Optimal Growth Conditions: We learned the importance of creating and maintaining optimal conditions for fungal growth. This included finding the right balance of temperature, humidity, and nutrient levels to ensure the fungi thrived and produced the necessary enzymes.
Pre-treatment Techniques: We explored various pre-treatment methods, such as UV light exposure, to enhance the plastic degradation process. This step proved crucial in making the plastic more susceptible to enzymatic breakdown.
What's next for Fungi : Friend or Foe
Scaling Up: We'll explore ways to scale up the fungi farming process to handle larger quantities of plastic waste. This involves designing larger bioreactors and optimizing the cultivation methods for industrial applications.
Commercial Viability: We aim to assess the commercial viability of our fungi-based plastic degradation system. This includes collaborating with waste management companies and exploring potential market opportunities.
Research and Development: Continued research is essential to discover new fungi species with even more efficient plastic-degrading enzymes. We also plan to experiment with different plastic types to expand the range of materials that can be broken down.
Environmental Impact Studies: We'll conduct comprehensive studies to evaluate the environmental impact of our process. This ensures that the byproducts of plastic decomposition are safe and beneficial for the environment.
