What Food Can Be Processed by the Tero Device?

Aliments dispersés sur une table en bois

Did you know that the Tero can process up to 95% of your food waste? It can even recycle and enhance certain foods that do not fit into the traditional compost bin, such as animal products (meat and fish) or dairy products.

It is therefore a simple, efficient and fast way to reuse your food scraps and turn them into a natural nutrient-rich fertilizer.

In this article, find out what foods can be disposed of in the Tero and why certain foods aren’t recommended for the device.

Happy reading!

Foods That You Can Put in the Tero Device

Before starting a transformation cycle of your food waste, here are the 5 golden rules to follow:

  1. Ensure that the food in the bucket has been valorized to their maximum to avoid food waste;
  2. Be sure to add small amounts of different foods;
  3. Be sure to respect the maximum filling line inside the bucket;
  4. Do not cut your food waste before placing it in the Tero, with the exception of robust or fibrous foods (banana peels, asparagus, celery, etc.), which must be cut into pieces about 1 inch;
  5. Add coffee grounds or eggshells to your waste to make it easier to get a better fertilizer texture.

Once these rules are applied, you can deposit the following food waste in your Tero:

    All of these foods are very easy to process and will be very beneficial to your soil and plants, especially with all the nutrients they contain.

    Also note that the Tero device is equipped with a grinding system that is robust enough to grind small chicken bones (wings or carcass) and fish bones. The avocado seed (which is actually quite soft) as well as corn cobs cut into sections can also be added.

    *Please note:

    • Even if a food can be processed by the device, it should be avoided to add a very large amount in a cycle, as this could result in a still wet or coarse fertilizer;
    • The following foods are more difficult to process because they can remain sticky, clump together or stick to the walls:
      • Very wet foods (tomatoes, cucumbers, watermelon, etc.)
      • Fatty foods (chips, meat, processed foods, etc.)
      • Starchy foods (rice, pasta, potatoes, etc.)
      • Very sweet fruits (melons, bananas, grapes, pineapples, etc.)
      • Desserts (cakes, pies, cookies, etc.) 
    • Fertilizer resulting from the processing of very salty foods (fast food, chips, ultraprocessed foods, etc.) should be used carefully in your plants, because too much sodium could harm them.

    The Tero device stands out from several other organic waste recycling solutions because it can process raw meat and fish. Why? Because its unique drying technology emits heat high enough to destroy all human-damaging pathogens found in this type of food. The final fertilizer material therefore has no chance of being contaminated.

    Finally, the more varied the processed foods are, the more you will get a rich and diverse natural nutrient fertilizer. 

    Foods That You Can't Put in the Tero Device

    It is important to note that for several reasons, some foods can never be processed by the Tero.

    Firstly, very hard food can damage the device, break the blades inside the bucket, or get stuck between the blades and block the motor. These include:

    Aliments non-admissibles dans le Tero

    Please note:

    • Liquid shouldn’t be used in large quantities, but you can put wet food in the device. For example, a glass of milk or soup broth cannot be processed, while chicken with sauce drippings or large food pieces in soup (pasta, meat, legumes) can be processed;
      • Too much liquid can damage the device by leaking into the heating or electrical system;
    • Too hard food could cause irreparable damage to the device;
    • Fats and oils in large quantities are too fat to be dehydrated by the device and could also harm the health of your plants;
    • The absence of microorganisms and bacteria in our process explains why paper, coffee filters, tea bags, handkerchiefs, paper towels or compostable bioplastics cannot be processed by Tero.

    In short, the Tero allows you to transform several foods into a natural nutrient-rich fertilizer for your lawn, outdoor plants or vegetable garden.

    Question: How long does the composting process take to have a finished end-product – fertilizer? For example: If I have 2 litre of fresh food waste in the container, how long will it take to become fertilizer? Thanks.

    Quelle est la garantie sur cet appareil? (mois, année) ?

    Si l’appareil est défectueux, aurons-nous des adresses pour le faire réparer ?

    Combien de temps, appoximativement, faut-il compter pour composter le plein contenu ?

    Pour une famille de six personnes, croyez-vous, selon votre expérience que nous devrons nous en servir tous les jours?

    Est-ce un appareil qui exige beaucoup d’électricité?

    Les filtres se vendent combien? Y aura-t-il des points de vente dans la ville de Québec?

    Merci de répondre à mes interrogations.

    Bonjour, je suis sur le projet depuis le tout début…..j’aime et j’y crois mais l’attente qui
    se prolonge sans cesse et commande sans nous assurer un date certaine m’ont déçue et crée un doute …J’en parlais maintenant j’attend, je voulais acheter et en offrir maintenant j’attend ….tout cela pour un délai pour pas seulement pour le produit mais pour crée une méga entreprise ….
    J’attend donc que le produit sera vraiment disponible pour acheter et recevoir avec date garantie près de la période de l’achat…

    Une fan pour un produit et 2 créatrices coup de cœur ….🌷
