Big Hanna, Covid-19 information

Susteco AB and our main suppliers are open but are of course taking the recommended precautions in order not to spread Covid-19.

We are available if you have any questions regarding composting, spare parts or machines.

We realize that some of our customers will have to shut down their machines for a period even though in general waste still have to be taken care of. It is easy to turn the Big Hanna off for a period without emptying the compost. 

This is how:

  • When you stop adding food waste, keep the current settings of your Big Hanna for another week.
  • After approximately one week, please note down the current settings and then change the settings so there is one rotation every 4 hours.
  • After a few weeks when the compost in the Big Hanna is as follows:
    • The material is dry.
    • The material looks like soil.
    • The temperatures in the biological process inside the cylinder are less 20 degrees in all material.
  • Turn off the Big Hanna, the material can stay inside the cylinder.

When you start adding food waste into Big Hanna again:

  • Turn the composter on.
  • For one week keep the settings so the machine rotates 1 time every 4th
  • After one week change the settings back to what it was before (the settings you noted before changing to one rotation every 4th hour).

If you have any questions, please just call us or send an email and we will guide you.

Take care and be safe.


Composting at MEF Schools, Istanbul, Turkey

We are pleased to announce that on 5 February 2020, a Big Hanna Composter model T120 with a biofilter was installed at MEF Schools for turning kitchen waste into fertilizer. MEF Schools is a well-known private national school located in the Ortaköy district of İstanbul, Turkey which has 2,000 students and 300 employees. Beside that academic and social success, MEF Schools has a goal of raising environmental awareness of their students. They are seriously focused on sustainable development and composting its food waste on-site helps reduce its carbon footprint.

MEF Schools cafeteria serves meals to students and employees every day. The food waste from the kitchen and the leftovers from the student’s cafeteria are composted in Big Hanna Composter T120 machine. Unilever Food Solutions in Turkey supported this project and the program has been implemented in cooperation with Beşiktaş Municipality. As partner of that project, Beşiktaş Municipality will use the finished compost as soil amendments in their green park areas. Also, the students are very interested with food waste composting process and willing to improve themselves for organic recycling.

Our distributor in Turkey, Ecotec’s CEO, Mehmet Başaran, successfully installed the machine and thereafter conducted training sessions at MEF Schools. Every year, millions of tons of food and yard waste goes to landfills and releases greenhouse gases. We hope that many other schools in Turkey will follow MEF Schools and play an active role in turning kitchen waste into compost and preventing climate change.
