Composting

May 2023 | Sustainable living

Composting is a natural process that converts organic waste into nutrient-rich soil. By composting, we can reduce the amount of waste sent to landfills and harness the environmental benefits that come with it. In this blog post, we will explore the importance of composting and its numerous benefits to the environment.

Waste Reduction and Landfill Diversion

Composting plays a vital role in waste reduction and landfill diversion. Organic waste, such as food scraps, garden trimmings, and paper products, accounts for a significant portion of landfill waste. When these materials are composted instead, they break down naturally, reducing the amount of waste that ends up in landfills. By diverting organic waste from landfills, we can extend the lifespan of landfills, reduce methane emissions (a potent greenhouse gas), and minimize the need for new landfill sites.

Soil Enrichment and Nutrient Recycling

One of the significant benefits of composting is its ability to enrich soil and recycle nutrients. Compost is a valuable organic fertilizer that improves soil structure, moisture retention, and nutrient content. When added to gardens, farms, or landscaping projects, compost enhances soil fertility, promotes healthy plant growth, and reduces the need for chemical fertilizers. Composting effectively closes the loop by recycling organic matter back into the earth, creating a sustainable cycle of nutrient replenishment.

Carbon Sequestration and Climate Change Mitigation

Composting contributes to climate change mitigation through carbon sequestration. When organic waste decomposes in landfills, it releases methane, a potent greenhouse gas that significantly contributes to global warming. In contrast, composting provides an aerobic environment where organic matter breaks down into carbon dioxide, a less harmful greenhouse gas. Additionally, compost-amended soils have better carbon retention capabilities, effectively storing carbon and reducing carbon dioxide levels in the atmosphere.

Water Conservation and Erosion Prevention

Compost plays a crucial role in water conservation and erosion prevention. Compost-amended soils have increased water-holding capacity, reducing the need for excessive irrigation. By improving soil structure, compost helps prevent soil erosion and runoff, which can contaminate water bodies with pollutants. Composting, therefore, supports sustainable water management practices and helps preserve precious water resources.

Biodiversity and Habitat Restoration

Composting promotes biodiversity and habitat restoration. By enriching soil with compost, we create a fertile environment for beneficial microorganisms, earthworms, and other soil organisms. These organisms contribute to healthy soil ecosystems, aiding in nutrient cycling and promoting plant diversity. Furthermore, compost can be used in ecological restoration projects to revitalize degraded areas, reclaim contaminated soils, and establish thriving habitats for native flora and fauna.

In conclusion

Composting is a simple yet powerful way to make a positive impact on the environment. By diverting organic waste from landfills, enriching soil, mitigating climate change, conserving water, and supporting biodiversity, composting provides a sustainable solution that benefits both our planet and future generations. Embracing composting practices is a step toward a greener and more sustainable future.

Here are some examples of items that you can compost:

  • Fruit and vegetable scraps: Including peels, cores, seeds, and trimmings.
  • Coffee grounds and filters: Used coffee grounds and paper filters can be composted. They provide nitrogen to the compost pile.
  • Tea leaves and bags: Tea leaves and tea bags (preferably made of natural fibres) can be composted. They add nutrients to the compost.
  • Eggshells: Crushed eggshells are a valuable source of calcium for the compost and help balance the pH level.
  • Garden waste: Leaves, grass clippings, plant trimmings, and small branches can all be composted. Shredding or chopping them into smaller pieces accelerates the decomposition process.
  • Shredded paper and cardboard: Paper materials such as newspaper, cardboard, office paper, and paper bags can be composted. Avoid glossy or heavily inked paper.
  • Dry leaves and hay: Fallen leaves and dry grass or straw can be added to the compost pile. They provide carbon and help with aeration.
  • Wood ash: Wood ash from fireplaces or wood-burning stoves can be composted in moderate amounts. It helps raise the pH level of acidic compost.
  • Plant-based food scraps: Non-meat kitchen scraps like bread, pasta, rice, and vegetable-based leftovers can be composted. Avoid dairy, oils, and fatty foods.
  • Seaweed and kelp: If you have access to fresh seaweed or kelp, they can be composted. Rinse them thoroughly to remove excess salt.
  • Nut shells: Shells from nuts like peanuts, walnuts, or almonds can be composted. However, avoid composting shells treated with preservatives or chemicals.
  • Sawdust and wood chips: Untreated and non-pressure-treated sawdust and wood chips can be composted. They add carbon to the compost pile.

Remember, for successful composting, it’s essential to maintain a balance between carbon-rich (browns) and nitrogen-rich (greens) materials. Aim for a carbon-to-nitrogen ratio of roughly 25-30 parts carbon to 1 part nitrogen. This balance ensures proper decomposition and a healthy composting process.

By composting a variety of organic materials, you can reduce waste, enrich your soil, and contribute to a more sustainable and eco-friendly lifestyle.
