BIOREMEDIATION Bioremediation is the use of living organisms (like bacteria, fungi, algae, or plants) to clean ip pollutants from soil, water, and air , making the environment healthier. 🔷 HOW IT WORKS 🔹 Microbes or plants break down, neutralize, or remove contaminants. 🔹 Pollutants like oil, pesticides, heavy metals, plastics, or sewage are converted into harmless products like CO2, water or biomass). 🔷 TYPES OF BIOREMEDIATION 1. In situ: 🔹 Bioventing- pumping oxygen/nutrients to stimulate microbes. 🔹 Biosparging- injecting air/nutrients into groundwater. 🔹 Phytoremediation- plants absorbing or stabilizing pollutants. 2. Ex situ: 🔹 Landfarming- spreading soil & stimulating microbial activity. 🔹 Composting- mixing pollutants with organic material for microbial breakdown. 🔹 Bioreactors- controlled tanks where microbes degrade pollutants. 🔷 ADVANTAGES 🔹 Eco-friendly and natural. 🔹 Cost-effective compared to chemical/physical cleanup. 🔹 Complete degradation (not just transferring pollution elsewhere). 🔷 LIMITATIONS 🔹 Takes time (weeks to years). 🔹 Not all pollutants are biodegradable (e.g., some heavy metals). 🔹 Effectiveness depends on temperature, pH, oxygen, and nutrients.
