Initiating tire recycling operations in 1996, Tire Recycling Atlantic Canada Corporation (TRACC), located in New Brunswick, Canada, has consistently expanded and modernized its facilities. Chances are, you or your children have encountered their products, whether it’s mats or playground surfaces. Notably, TRACC has diversified its offerings to include robust rubber landscaping mulch, available in three colors – black, cedar, or brown.

Other notable suppliers of recycled rubber mulch in North America encompass Rymar Rubber and HEFFCO. To explore the availability of these products, it is advisable to inquire at your local home renovation store.

To assess the sustainability of recycled rubber mulch in comparison to wood mulch, we will delve into various features of these landscaping options in the discussion that follows.

1. What Are the Advantages of Wood Mulch

• It is a biodegradable material that naturally decomposes and returns to the soil.
• Low energy consumption is associated with its production, as it is a byproduct of wood processing.
• Bark mulch, a common type of wood mulch, is relatively inert and decomposes at a slow rate, helping to preserve soil nutrients.
• Typically, non-toxic iron oxide and carbon black dyes are employed for coloration. In some cases, additional colors are achieved using vegetable-based dyes.

2. What Are the Drawbacks of Wood Mulch

• The material undergoes relatively rapid biodegradation.
• Regular replacement is necessary, typically every year or two, due to decomposition or washout.
• Decomposition of wood mulch results in the removal of nitrogen nutrients from the soil.
• It tends to mat down, forming a barrier that hinders water penetration and airflow.
• Recycled wood mulch may carry potential risks, such as the presence of toxic substances like arsenic or creosote from inadequately sorted treated lumber waste.

3. What Are the Advantages of Recycled Rubber Mulch

Utilizes repurposed waste products, specifically recycled tires, thereby reducing disposal impacts:

• Exhibits water resistance, as it does not absorb water.
• Acts as a deterrent to fungus and mold development.
• Provides insulation to the soil, protecting it from excessive heat and adverse weather conditions.
• Retains its aesthetic appeal consistently across different seasons.
• Demonstrates resilience against compression, wind dispersal, and washout.
• Effectively controls weed growth, with weed seeds dehydrating in the mulch before reaching the soil.

4. What Are the Drawbacks of Recycled Rubber Mulch

• Lacks biodegradability, as it does not naturally break down over time.
• Fails to contribute to soil enrichment or increased soil biodiversity through decomposition.
• Poses a hazard when ignited due to the burning of rubber.
• Presents challenges for removal once settled into the ground; it cannot be easily tilled into the soil.
• Carries the risk of soil contamination with metals if the tires were not adequately processed during production.

5. How Is Recycled Rubber Mulch Made

The production process of recycled rubber mulch involves the transformation of ground-up new, defective, or used tires, along with waste tire buffing’s that would otherwise be destined for landfills. This intricate manufacturing procedure commences with the thorough cleaning of the tires, ensuring the removal of any contaminants.

Subsequently, metal wires are extracted from the tires, and the remaining rubber is shredded into diverse sizes, tailored to the specific intended applications of the mulch. This meticulous process not only repurposes discarded tires but also ensures the creation of a versatile and eco-friendly material that can be employed in various landscaping contexts.

6. Does Recycled Rubber Mulch Contain Metal

Recycled rubber mulch may potentially contain residual metal strands that were inadvertently missed during the manufacturing process. To ensure the absence of such metal components, it is advisable to reach out to the manufacturer and inquire about their production methods, specifically those addressing metal removal.

As a precautionary measure, when applying rubber mulch, it is recommended to wear protective gloves and knee pads to safeguard against any unexpected presence of metal elements. This added diligence contributes to a safer and more secure application of recycled rubber mulch in various landscaping scenarios.

7. Can Rubber Mulch Pose Toxicity Risks to Plants

Recycled rubber mulch may contain zinc, and while it is generally free from diseases caused by pathogens, it’s important to consider the potential impact of elevated zinc levels on plant growth.

While high levels of zinc can act as an inhibitor for plant development, in cases of zinc-deficient soils, rubber mulch can actually serve as a beneficial source of zinc fertilizer, contributing to the overall health and nourishment of plants.

It is crucial to carefully assess the specific soil conditions and zinc levels before applying recycled rubber mulch to ensure optimal plant well-being and growth.

8. Is Recycled Rubber Mulch Heavy

Recycled rubber mulch tends to be weightier compared to wood mulch, making transportation more challenging. To address this, consider sourcing from a local manufacturer or supplier to minimize transport distances. Despite its weight, the heaviness of recycled rubber mulch contributes to enhanced durability and longevity, especially in the face of heavy rain and strong winds, surpassing the resilience of wood mulch.

9. How Much Does Recycled Rubber Mulch Cost?

The cost of recycled rubber mulch typically ranges from $8 to $14 per cubic foot, contingent upon the grade and quantity purchased. In contrast, natural wood mulch is priced at $2 to $3 per cubic foot.

Although recycled rubber mulch commands a higher initial cost, its prolonged lifespan, lasting up to ten years or more according to most manufacturers, proves to be a cost-effective investment. This is in stark contrast to wood mulch, which necessitates replacement approximately every two years, contributing to additional expenses over time.

10. How Long Does Recycled Rubber Mulch Last

Recycled rubber mulch boasts an extended lifespan when compared to its wood counterpart. Many manufacturers indicate that recycled rubber mulch can endure for a minimum of ten years, if not longer. The dyes used in the manufacturing process of rubber mulch also exhibit greater resistance to fading and deterioration compared to those used in wood mulch. This prolonged durability makes recycled rubber mulch a reliable and enduring choice for landscaping, ensuring lasting aesthetic appeal and functionality over an extended period.

11. Is Recycled Rubber Mulch Safe?

Neither the Environmental Protection Agency (EPA) nor the Consumer Product Safety Commission has explicitly declared crumb rubber as unequivocally safe. Both organizations have emphasized the need for additional studies.

Despite this, they recommend and endorse the use of rubber mulch. It’s important to note that rubber mulches can leach various plasticizers and accelerators utilized in tire manufacturing into the soil. Therefore, it is imperative to choose products that have undergone testing for leaching and pose no risks to individuals or the environment.

12. Does Rubber Mulch Cause Cancer

Research thus far has not established a link between recycled rubber mulch and cancer. The EPA has concluded that while certain harmful chemicals may be present, exposure to these substances is not associated with adverse health effects in humans. However, it is crucial to recognize that different mulches have distinct compositions.

To ensure safety, inquire about the source and production process from your supplier. For instance, recycled wood mulch should exclude treated lumber containing arsenic and creosote, while recycled rubber mulch should be free of metals.

While recycled rubber mulch may entail a higher initial cost, its longer lifespan often translates to lower long-term expenses. It is advisable to compare prices among suppliers to make an informed decision based on both upfront and long-term costs.

Final Conclusion

In conclusion, both wood chip mulch and recycled rubber mulch emerge as sustainable products, utilizing byproducts from various processing methods and not requiring additional material resources from the earth. When contemplating the right choice for your upcoming landscaping project, several pivotal considerations should guide your decision-making. Firstly, evaluate whether you prioritize a durable product that doesn’t necessitate frequent replacements, or if a more biodegradable option aligns better with your preferences.
