What is Commercial Composting?

Commercial composting is the large-scale process of turning organic waste into nutrient-rich compost. It plays a vital role in reducing landfill waste and promoting environmental sustainability.

Definition and purpose

Commercial composting turns organic waste into valuable compost, helping in environmental conservation. This process involves transforming food scraps and biodegradable materials into nutrient-rich soil but it should never be allowed to add microplastic.

It aims at reducing methane emissions from landfills and enriching the soil, supporting sustainable agriculture practices.

Mastering the art of microplastic-free commercial compost-making enhances soil health by removing harmful tiny pieces of plastic pollutants. Unless and until certification associations like BPI are appointed to ensure that only truly compostable materials enter this cycle, minimising microplastic pollution by removing the plastic before it inters the feedstock stream.

From my experience working with various compost facilities, it’s crucial to verify that they remove the plastic first and only accept certified compostable materials to go into the first stage of commercial (windrow or in-vessel) composting. This is needed to maintain the integrity of the end product. Establishing a balanced mix of organics and completing aerobic phases are pivotal steps before screening out non-compostables, as outlined in the Master Composter Manual.

Composting organic waste not only reduces methane emissions but also turns potential landfill material into gold for our gardens, – this encapsulates why mastering microplastic-free commercial compost making is vital for both our plants and planet.

Benefits for the environment

Composting food and organic waste is a sustainable practice that helps in reducing harmful methane emissions and enriching the soil but only worthwhile if the little bits of plastic (microplastic) don’t go though after screening into the compost. This environmentally friendly approach not only supports waste reduction but also promotes eco-friendly practices, aligning with sustainability initiatives.

Additionally, when certified compostable materials are used for commercial compost making, it contributes towards organic recycling programmes and green initiatives, thus reducing landfill waste.

Furthermore, providing composting workshops can help unlock the secrets to mastering the art of microplastic-free commercial compost making through firsthand experience, guiding individuals and businesses towards embracing waste-wise practices.

How Does Commercial Composting Work?

Commercial composting involves the biological breakdown of organic matter on an industrial scale. This process utilises various methods to facilitate the decomposition of organic materials and turn them into nutrient-rich compost for agricultural and horticultural use.

Methods for industrial composting

Industrial composting involves large-scale organic waste processing at dedicated facilities, catering to the needs of commercial enterprises. The methods for industrial composting are as follows:

  1. Utilising windrow composting systems:
    • Windrows are long piles of organic materials turned regularly to maintain airflow and promote decomposition.
    • These systems use large machinery to manage and turn the windrows for effective aeration and temperature control.

  2. Implementing aerated static pile (ASP) composting:
    • ASP composting involves mixing organic waste with bulking agents and providing controlled aeration through pipes or blowers.
    • This method accelerates decomposition by maintaining optimal moisture and oxygen levels.

  3. Employing in-vessel composting techniques:
    • In-vessel composting utilises enclosed containers or reactors to process organic waste under controlled conditions.
    • These systems offer precise control over temperature, moisture, and aeration, accelerating the composting process.

  4. Using mechanical sorting technologies:
    • Incorporating depackaging and separation machinery to sort incoming waste materials that soes not use particle size reduction facilitates the removal of contaminants and non-compostable items.This is essential to minimise the presence of plastic contamination in the final compost product.
  5. Ensuring proper curing and maturation:
    • Compost materials undergo a curing phase after active decomposition to stabilise nutrient content and eliminate pathogens.
    • Maturation typically occurs outdoors, allowing for further breakdown of organic matter before it is ready for use.

Industrial composting methods aim to efficiently process large volumes of organic waste while minimising microplastic pollution in the final compost product, ensuring ecological sustainability within commercial operations.

The Problem with Microplastics in Compost: Why Size Matters

While mechanical sorting with machinery helps remove contaminants, it’s crucial to understand that simply shredding plastic into smaller and smaller pieces isn’t the answer for microplastic-free compost. Here’s why:

  • Plastic Doesn’t Decompose: Unlike organic materials, plastic doesn’t break down naturally. It gets fragmented into ever-tinier microplastics through mechanical processes or weathering in the environment. These microplastics, invisible to the naked eye, become a significant threat.
  • Microplastics: A Growing Environmental Concern: Microplastics have infiltrated nearly every corner of our planet, from the deepest ocean trenches to the peaks of mountains. They are ingested by wildlife, disrupting ecosystems and potentially harming human health. Studies have even found microplastics in our bloodstreams, highlighting the pervasiveness of this issue.

The New Frontier: Depackaging Technology

This is where the latest depackaging technology comes in. Unlike traditional methods that rely on size reduction, these innovative solutions are designed from the ground up to remove plastic entirely without creating microplastic fragments. This is an essential shift because the old approach of shredding plastic simply creates a bigger problem down the line.

By embracing these new depackaging technologies, we can ensure truly microplastic-free compost that nourishes our gardens without harming the environment.

Importance of proper management

Proper management is crucial for successful commercial composting. Understanding what can and cannot be composted, as well as creating a balanced mix, is vital to reducing microplastic pollution in compost.

Aerobic composting phases need to be completed meticulously before screening the material for non-compostable items and oversized materials. It’s important to establish a suitable place for food scrap storage and set up proper compost bins for effective waste decomposition.

Certification associations like BPI play a key role in verifying the suitability of compostable materials while city guides offer useful tips for mastering microplastic-free commercial compost making.
