Why Biofiltration Media is superior to mulch and bark in tackling VOC Pollution

Biofiltration media is significantly more effective than mulch or bark when it comes to controlling volatile organic compounds (VOCs) due to several key factors.

Biofiltration media is significantly more effective than common mulch or bark when it comes to controlling volatile organic compounds (VOCs) due to several key factors.

Biofiltration - a superior solution for managing VOCs

1. Greater Effectiveness with Lower Maintenance:
Unlike common mulch or bark used for filtration, which can create “hotspots” over time and reduce efficiency, biofiltration media is specifically engineered to consistently mitigate odours without frequent, short-term maintenance. This reduces the risk of VOC release, protecting both ecological and public health.
2. Optimised Surface Area for Microbial Growth:
Biofiltration media is designed to maximise surface area, supporting the growth of a diverse microbial community that effectively breaks down VOCs.
3. Superior Moisture Retention:
Biofiltration media retains moisture significantly better than standard mulch or bark, providing a stable, moist environment essential for VOC-degrading microbes, especially in dry or hot conditions where mulch dries out quickly.
4. Durability and Longevity:
Biofiltration media resists decomposition far longer than mulch or bark, maintaining its effectiveness and reducing the need for frequent replacement, making it a more dependable, long-term VOC control solution.
5. Targeted VOC Adsorption:
Unlike mulch or bark, biofiltration media can be customised to adsorb and break down specific VOCs, enhancing its efficiency at neutralising harmful compounds that threaten environmental and human health.
