How does green waste treatment at highway reduce water consumption over time?

As the world faces urgent challenges in environmental conservation and sustainability, innovative approaches are more crucial than ever. Highways, the lifelines of our transportation systems, produce substantial amounts of green waste—grass clippings, tree trimmings, and organic debris. Often overlooked, this waste holds immense promise for environmental benefits.

In this blog, we’ll explore how effective management and treatment of highway green waste can significantly contribute to a healthier planet. From reducing landfill usage to creating renewable energy and enhancing soil quality, the possibilities are both diverse and impactful.

One of the major hurdles in this process is the practical treatment of green waste generated along highway routes. Setting up designated areas for waste management often proves unfeasible due to challenges like supervision, labor requirements, safety protocols, and the need for dedicated personnel. As a result, less sustainable methods—such as burning or using pit composting systems—are frequently adopted, despite their environmental drawbacks.

Let’s reimagine these challenges as opportunities for innovation and sustainable change!

When burned, wood produces more CO2 emissions per unit of energy than fossil fuels. For example, burning 1 kg of wood releases approximately 1.80 kg of CO2, contributing to greenhouse gas (GHG) emissions that significantly impact the environment.

Alternatively, pit composting of green waste presents its own set of challenges:

• It requires additional labor for excavating pits along highways.
• The decomposition process is slow, often taking several years to complete.
• The compost eventually blends with the surrounding soil, making it difficult to harvest or utilize effectively.

What is the green waste composting solution available for highway?

An effective solution for managing green waste along highways is to establish composting heaps made from shredded green waste. By integrating a microbial consortium into the waste and covering the heaps with shading nets, we can prevent debris from blowing onto roads during windy conditions and ensure efficient decomposition. These composting heaps can be set up at 2-kilometer intervals along the highways. Using the existing workforce, the harvested compost can be applied to nourish the plants in highway medians, fostering a sustainable and environmentally friendly approach to highway maintenance.

How Does Green Waste Treatment Along Highways Reduce Water Consumption Over Time?

Incorporating compost into the soil significantly reduces the water required for plant maintenance. Compost-enriched soil can retain up to 2.5 times more water than traditional soil, decreasing the frequency and quantity of watering needed. This process not only conserves water but also improves soil health and plant growth.

Key Benefits of Compost in Soil:

• Soil Regeneration: Restores soil structure and fertility.
• Enhanced Moisture Retention: Helps soil hold more water, reducing evaporation and runoff.
• Improved Nutrient Supply: Provides a threefold higher NPK ratio with a slow release of nutrients to plants.
• Nutrient Solubility: Converts soil nutrients into a water-soluble form, making them more accessible to plants.

By treating green waste effectively, highways can adopt a sustainable approach that benefits both the environment and water resources.
