Liquid waste:
Fluid wastes, consisting of sewage and domestic wastewater, or processed water, or
other liquids, produced by industrial activity, particularly by such industries as pulp and paper
production, food processing, and the manufacture of chemicals.
Hazardous waste:
Any waste or combination of wastes with the potential to damage human health,
living organisms or the environment. Hazardous wastes usually require special handling and disposal
procedures which are regulated by national and international laws.
Pesticides:
A general term for chemical substances that are used to destroy or control insect or plant
pests. Many pesticides are manufactured and do not occur naturally in the environment. Others are
natural toxics that are extracted from plants and animals.

RANGE OF APPLICATION AND LIMITATIONS OF USE
The Big Hanna Composter is designed for food waste, sawdust/pelletised sawdust (together with food
waste or water) only.
‘Food waste’ as the first definition in 1.6.3 is possible to compost in the Big Hanna Composter if it is a
proper mix, temperature, appropriate size (1-5 cm) and has a suitable moisture content. (Too much
liquid seriously inhibits the biological process.) Most food waste from residences is suitable for
composting as long as it is not contaminated by non food waste.
In general all ‘food waste’ in the second definition in 1.6.3 can be composted with the exception of
beverages. However also with this definition the mix, temperature, size and moisture content must be
appropriate.
The Big Hanna Composter is manufactured especially with food waste in mind. Not all organic or
compostable wastes are suitable.
Note that this composter is not designed for processing organic waste such as animal waste,
agricultural waste or liquid waste. If you want to use this machine for anything other than
composting food waste within the limitations described above together with sawdust or
pelletised sawdust ask the distributor’s advice or proceed at your own risk.
Garden waste can be put into the Big Hanna Composter only in smaller pieces (2-3 cm) and might not
decompose properly depending on type. The compost process is a biological process, which must be
treated with care in order to obtain a good result i.e. a good compost material that can be used as a
fertiliser. The waste material that is put into the machine must be cleared from materials that may
damage the equipment or disturb the biological process.
Where the Big Hanna Composter is used the above limitations is rarely a problem and the sorting of
food is done on another ‘level’. To help tenants and staff to sort the food waste see chapter ‘What to
put in the composter’ and ‘4.2.2 What not to put in the composter’. This gives hands-on suggestions
on practical sorting but is not a conclusive list of what is and is not suitable for composting.
Detergents used in food preparation, cooking area, around the composter or where it may come in
contact with the food waste should be organic and not bio accumulating.
The information about obtaining temperatures and the biological process in this manual
constitutes no guarantee to do so by the manufacturer.
