The Power of Worms | Erich Fässler | TEDxHochschuleLuzern

Introduction

This tutorial explores the innovative use of worms in recycling organic waste to create nutrient-rich fertilizer. Inspired by Erich Fässler's TEDx talk, this guide will help you understand how to implement a stylish composting system in your home or community, transforming food waste into valuable resources for your plants.

Step 1: Understand the Benefits of Worm Composting

• Nutrient-Rich Fertilizer: Worm composting produces vermicompost, which is rich in essential nutrients for plants.
• Waste Reduction: Composting with worms helps reduce the amount of organic waste sent to landfills.
• Sustainable Practice: Encourages a more sustainable lifestyle by recycling kitchen scraps.

Step 2: Choose the Right Worms

• Select the Right Species: The most common worms for composting are Red Wigglers (Eisenia fetida) and European Nightcrawlers (Eisenia hortensis).
• Purchase from Reliable Sources: Buy worms from local suppliers or online stores specializing in vermiculture.

Step 3: Set Up Your Composting System

• Choose a Container: Use a worm bin made of plastic, wood, or metal. Ensure it has proper ventilation and drainage.
• Create a Bedding Layer:
  • Use materials like shredded newspaper, cardboard, or coconut coir.
  • Moisten the bedding slightly to provide a comfortable environment for the worms.
• Add Worms: Introduce the worms into their new home on top of the bedding.

Step 4: Feed Your Worms Properly

• Select Food Scraps: Feed worms organic waste such as vegetable peels, fruit scraps, coffee grounds, and crushed eggshells.
• Avoid Certain Foods: Do not feed worms meat, dairy, oily foods, or citrus, as these can harm them and create odors.
• Feed in Moderation: Start with small amounts to allow worms to adjust, then gradually increase as they eat through the scraps.

Step 5: Maintain the Worm Bin

• Monitor Moisture Levels: The bin should be damp but not soggy. Spray with water if it becomes too dry.
• Check Temperature: Ideal temperature for worms is between 60°F and 70°F (15°C - 21°C).
• Turn the Bedding: Occasionally mix the bedding to aerate it and help distribute food.

Step 6: Harvest the Vermicompost

• Timing: Harvest vermicompost every 3 to 6 months when the bedding material is mostly decomposed.
• Separate Worms from Compost:
  • Move the compost to one side of the bin.
  • Add fresh bedding and food to the other side.
  • Worms will migrate towards the food, allowing you to collect the finished compost.

Conclusion

Implementing a worm composting system is a simple yet powerful way to recycle organic waste into a valuable resource for your plants. By following these steps, you can contribute to a more sustainable environment while enjoying the benefits of nutrient-rich fertilizer. Consider sharing your experience with others to promote eco-friendly practices in your community.
