Our food waste converters utilise our proprietary biotechnology that convert food and other organic waste into a highly-valued, dry, safe and nutrient-rich soil product / biofertilizer in less than 24 hours.

Our proprietary Biotechnology converts food and other organic waste into a highly-valued, dry, safe and nutrient-rich soil product / biofertilizer in less than 24hrs.

Our advanced technology can process various types of difficult waste material, including organic waste, food waste, agricultural waste, and more.

We recommend adding only BPI Certified Compostables. These products bear the BPI logo, ensuring they meet strict compostability standards and are designed to break down effectively in our biodigester. Not all biodegradable items meet these criteria for proper breakdown and compostability.

Non-certified compostable items might not break down efficiently or could cause disruptions in the biodigester’s operation. This could result in incomplete decomposition, slowing down the composting process or leading to issues.

The machine requires at least 40% of its designed capacity to operate effectively.

Pre-processing isn’t necessary, but shredding materials can speed up the degradation process and make it more efficient.

Nothing. The system can remain dormant for several months. When it is restarted and reaches the operating temperature, the process resumes automatically. Microbes in the system become active once they come into contact with moisture, ensuring normal operation continues.

After the initial slow feed for the first 2 to 3 weeks you can put up to 2 kg per day (this needs to be done in 2/3 separate feeds) and up to a maximum of 10kg per week.

You can utilize compost by incorporating it into the soil of flowerpots, established plants, and trees, as well as spreading it on that patch of lawn that’s not doing so well; however, caution is necessary due to its nutrient-rich composition, so a recommended ratio of 9 parts soil to 1 part compost ensures safe and efficient growth rates, and additionally, you can dilute the fine compost in a watering can to nourish your plants during the summer, providing cost savings compared to artificial growth stimulants.

It uses about 1.5 kwh’s per day, very similar to a small fridge.

By incorporating compost into your gardening practices, you not only experience various economic and social benefits but also contribute to the fight against greenhouse gases and help close the loop to get nutrients back into the soil, effectively turning your waste into fertilizer for a happier and healthier garden; moreover, this conscious approach towards food wastage helps prevent waste, leading to cost savings, while also reducing the amount of food waste in your black bin, resulting in weight reduction of up to 20 kg over a two-week period and saving you money on pay-by-weight bin charges.

You can put all types of food waste into it, peelings, leftover food, raw food, cooked food, food that has gone off. Just remember that it breaks down easier if you cut it up into thumb size particles, especially hard veg like carrots, turnip, broccoli stalks etc.

Do not put any packaging, bones, cutlery, biodegradable bags, medicines, shellfish, paper towels, cigarette buts, fish bones.

It’s simple, just wait until the compost is up to the max line and try not to put any more food in for 24/48 hrs, you then take the scoop supplied and just scoop out and store in an airtight container, then its ready to fertilise your garden and plants. Happy Gardening!!!!!!
