What is Bioremediation?

Bioremediation is the use of microorganisms, plants, and fungi to remove or neutralize contaminants, allying with living systems to detoxify contaminated environments. Many micro-organisms, plants and fungi are able to bind, extract or transform contaminants to create less toxic, healthier, and increasingly resilient ecosystems.

This class will provide an introduction to different bioremediation tools and techniques for detoxifying and revitalizing the gardens, lands and waters that sustain and nourish our communities, highlighting bioremediation projects and inspiring practitioners who are working with regenerative remedies to heal toxic realities.

Defining Terms 

  • Microbial Remediation: Treating contaminated areas with microorganisms to remove and break down pollutants
  • Mycoremediation: Cleaning water, and soil with fungi
  • Phytoremediation: Cleaning water, and soil with plants

What You’ll Be Learning 

  • Session 1 – Bioremediation Overview & Microbial Remediation: Definition and overview of bioremediation  techniques. Site assessment and testing for contamination. Contaminants 101: metals and chemical pollutants.  Introduction to microbial remediation and key site  considerations. Microbial remediation tools (thermophyllic compost, actively aerated compost tea, vermiculture, biochar)
  • Session 2 – Phytoremediation: Types of phytoremediation. Site preparation and considerations. Indicator plants. Key plant species for different remediation scenarios. Hyper accumulators and heavy metal extraction. Phytofiltration. Case studies and application: lead remediation
  • Session 3 – Mycoremediation: Introduction to mycoremediation. Types of fungi and their remediation and restoration applications. Decolonizing mycology. Site considerations, preparation, and maintenance for mycoremediation projects. Key fungi species and remediation installations. Mycofiltration. Training mycelium.
  • Session 4 – Bioremediation & Disasters,  Part 1 –  Wildfires: Post-wildfire contaminants and ecological impacts. Bioremediation responses for post-wildfire contamination. Case studies in post-wildfire bioremediation recovery, restoration, and myco-mitigation. Special guest presentation by Taye Bright & Maya Elson (CoRenewal), and Cheetah Tchudi (Butte Remediation)
  • Session 5 – Community Bioremediation Project Design: Tips for designing successful bioremediation projects, including building remediation teams, securing project funding and donations, developing testing plans and remediation plans. Community engagement. Special presentations on Ardawa Project (Bethlehem, Palestine) and Rhizae Renewal Collective (Baltimore).  Guest speakers: Mohammed Saleh (Palestinian Permaculturalist, Mostadam EcoDesign & Ardawa Project) & Robin Gukle (Rhizae Renewal Collective).
  • Session 6 –  Oil Spills and Self Care for Bioremediators & Frontline Communities: Oil spill behavior & conventional clean-up. Bioremediation tools for oil spill response. Protective equipment and safety protocols. Self Care & Community Care – working with plants and fungi for self care, health, and resilience in toxic environments.

Every class will include case studies to learn from real life examples and applications.

Bioremediation heals contaminated soils in order to grow safe and healthy food for our community.
