Worm composting in apartments: challenges and solutions for urban composting

CONTENTS

Introduction

At a time when environmental awareness has become a priority, recycling organic waste is an obvious solution. At the heart of this dynamic, vermicomposting stands out for its efficiency and simplicity. It's not just about composting: it's a real revolution for residents of urban areas, an ingenious way to integrate nature into an urban environment. In the confined confines of an apartment, vermicomposting offers an opportunity to transform our kitchen waste into valuable soil conditioner for plants, while significantly reducing our ecological footprint. So how does worm composting fit into the apartment environment? What are the challenges to be faced and how can they be overcome?

UNDERSTANDING VERMICOMPOSTING IN AN APARTMENT

Vermicomposting is a method based on the use of earthworms (belonging to the earthworm family, hence the term vermicomposting), to transform organic waste into humus. Compost worms digest organic matter, accelerating their decomposition while enriching the compost (called vermicompost) with minerals, nutrients and microorganisms. In urban environments, waste management becomes crucial. The ability to decompose household waste on site not only reduces the amount of waste transported, but also contributes to an ecological cycle, transforming our waste into natural fertilizer for houseplants or planters.

HOW THE VERMICOMPOSTER WORKS

The worm composter is a miniature ecosystem, where organic waste meets decomposer agents, in particular compost worms, to produce rich and fertile vermicompost. Its operation is based on several steps and key elements.

1. Adding waste

Organic waste such as peelings, coffee grounds and certain plant residues such as wilted flowers are added to the upper part of the worm composter. It is essential to vary the types of waste to ensure nutritional balance. Grass clippings and other branches will instead go into an outdoor composter.

2. Action of worms

Compost worms, notably the species Eisenia fetida or Eisenia andrei, feed on this waste. By digesting them, they speed up decomposition and enrich the mixture of their excrement, creating rich vermicompost.

3. Compost retrieval

Over time, the vermicompost matures and accumulates in the lower compartment. It can be harvested regularly and used as a powerful fertilizer for plants.

4. Retrieval of compost “tea”

Some worm composters, like the City Worms®, have a liquid recovery system. This “tea” (or vermithe) is a nutrient concentrate for plants, to be diluted before use.

By understanding and respecting these steps, the worm composter becomes a valuable tool for transforming our waste into resources, closing the loop of consumption in an eco-responsible way.

THE CHALLENGES OF VERMICOMPOSTING IN APARTMENTS

Space management

In an apartment, every square centimeter counts. A worm composter must be designed to optimize space while being efficient. Its size and shape must allow discreet integration, whether in a kitchen, a balcony or a laundry room.

The importance of ventilation

Good vermicomposting requires adequate aeration to avoid anaerobic fermentation (without oxygen) which could generate odors. Perforations, grilles or ventilation systems can be incorporated to ensure continuous airflow.

Temperature regulation

A stable environment is crucial for worms. Extreme temperatures can kill them or slow their activity. The location of the worm composter, far from direct sources of heat or cold, is therefore essential. Above 35°C and below 0°C, your little worms will die, be careful. Positioning the worm composter in a place where there are few temperature variations, such as the kitchen, a shaded room or a corner of the living room, is a solution. It must also be accessible to facilitate adding waste and harvesting vermicompost.

Waste management

Knowing what to compost is crucial. While peelings, coffee grounds, tea bags and egg shells are ideal, certain waste such as plate scraps, citrus fruits, onions, meat, fish or dairy products should be avoided because they can unbalance the pH or attract pests.
