Che cos'è il compost industriale rispetto a quello domestico?

Composting is a vital process for reducing waste and promoting sustainability, but not all composting methods are the same. Industrial composting e home composting are two distinct processes, each with its requirements and capabilities. Understanding these differences is essential for making informed decisions about compostable materials and sustainable waste management.

With growing global concerns about plastic pollution and landfill overflow, composting provides a promising alternative. But how do industrial and home composting work? What products can be composted in each system? How can consumers identify truly compostable products? In this article, we will explore these key topics and discuss the future of eco-friendly composting.

What is Industrial Compost?

Industrial composting is a large-scale process designed to efficiently break down biodegradable materials under controlled conditions. These facilities maintain high temperatures (above 55°C/131°F), specific moisture levels, and adequate aeration to accelerate decomposition. The result is high-quality compost that can be used in agriculture, landscaping, and soil restoration.

How Industrial Composting Works

1. Collection & Sorting: Organic waste and compostable materials are collected and sorted to remove contaminants.
2. Shredding & Mixing: Materials are shredded to increase surface area, ensuring faster breakdown.
3. Composting Phase: The mixture is placed in windrows, aerated piles, or in-vessel systems where temperature, moisture, and oxygen are regulated.
4. Maturation: After several weeks or months, the compost stabilizes and becomes a nutrient-rich soil conditioner.

Products That Can Be Industrially Composted

Not all biodegradable materials can break down efficiently in home compost bins. Some require higher temperatures and controlled conditions of industrial composting. Below are some examples of products that are suitable for industrial composting:

1. Compostable bioplastics (PLA, PHA)
2. Certified imballaggi alimentari compostabili
3. Compostable coffee cups & lids
4. Posate compostabili
5. Piatti di carta compostabili
6. Compostable trash bags
7. Compostable takeout containers
8. Compostable tea bags & coffee filters
9. Paper-based compostable packaging with biodegradable coatings
10. Agricultural compostable mulch films
11. Compostable hygiene products (certain wipes, diapers, sanitary products)

What is Home Compost?

Home composting is a natural decomposition process that occurs in backyard compost bins or piles, where organic waste is broken down by microorganisms, fungi, and worms. Unlike industrial composting, home composting does not involve high temperatures o mechanical processing. It is a slower process but provides an accessible and cost-effective way to reduce household waste.

How Home Composting Works

1. Layering: A balanced mix of green waste (food scraps, grass clippings) e brown waste (dry leaves, cardboard, paper) is added.
2. Aeration: The compost pile is turned regularly to ensure oxygen circulation.
3. Moisture Control: Water is occasionally added to maintain an optimal moisture level.
4. Decomposition: Microorganisms break down the materials over several weeks to months, creating nutrient-rich compost.

Products That Can Be Home Composted

Many biodegradable products decompose well in a home composting system. Below are some examples:

1. Fruit and vegetable scraps
2. Eggshells
3. Coffee grounds and paper coffee filters
4. Tea leaves and unbleached tea bags
5. Uncoated paper napkins and paper towels
6. Shredded cardboard and newspaper
7. Yard waste (grass clippings, leaves, twigs)
8. Wood-based compostable cutlery (if untreated)
9. 100% natural fiber fabric scraps (cotton, wool, hemp)
10. Pet fur and human hair

The Difference Between Industrial Compost and Home Compost?

While both methods aim to break down organic waste into nutrient-rich compost, their processes, conditions, and capabilities vary significantly.

1. Temperature & Processing Time:
   • Industrial composting requires high temperatures (above 55°C) and can break down materials in a few weeks.
   • Home composting relies on lower temperatures and can take several months.
2. Types of Materials Accepted:
   • Industrial composting can handle compostable plastics, coated paper products, and larger waste items that require high heat.
   • Home composting is limited to natural, organic materials like food scraps and plant-based waste.
3. Degradation Efficiency:
   • Industrial composting ensures full breakdown without residue.
   • Home composting may leave traces of certain materials, especially bioplastics.

How to Identify If a Product Is Compostable?

Identifying compostable products is essential to ensuring they break down as intended. Here are key indicators:

1. Certifications from International Organizations

• BPI (Biodegradable Products Institute) – USA
• TÜV Austria (OK Compost & OK Compost Home) – Europe
• DIN CERTCO – Germany
• Australasian Bioplastics Association (ABA) – Australia & New Zealand

2. Certified Product Labels

Look for “Certified Compostable” labels with certification numbers on the packaging or product’s body. These indicate the product meets industry standards.

3. Material Composition

• Industrial compostable materials: PLA (polylactic acid), PHA, PBAT (polybutyrate adipate terephthalate)
• Home compostable materials: Natural fibers, untreated wood, paper-based products

Future Trends in Compostable and Sustainable Solutions

As the global push for sustainable waste management increases, compostable materials are becoming more mainstream. Key trends include:

1. Advancements in Biodegradable Packaging: Companies are developing stronger, more versatile compostable plastics to replace single-use plastics.
2. Government Regulations: Many countries, including the EU, Canada, and the US, are enforcing bans on non-compostable plastics.
3. Corporate Sustainability Initiatives: Major brands like Unilever, Nestlé, and Coca-Cola are adopting compostable packaging to meet environmental goals.
4. Consumer Awareness & Demand: More consumers are choosing compostable over traditional plastic as awareness of plastic pollution grows.
