The disposal of food wastes, such as
- wastes from food preparation and table scraps
- by-products from fishing and fish processing
- by-products from slaughterhouses and butcher shops
- egg shells, etc.
is an increasingly significant problem for many reasons
| 1. | Use as livestock feed is increasingly limited for reasons of disease control, cannibalism issues and for improvements in meat quality. |
| 2. | Quantity reduction by shredding and compacting generates sewer loads of fibers and fats to an extent that many local authorities have prohibited this type of processing. |
| 3. | Fermentation, capture of biogas for heat or as fuel, is currently still too inefficient and very costly. |
| 4. | Incineration of the resource materials makes no sense on an ecological and ethical basis. |
| 5. | The environmental load from transports of food wastes and hog feed with an average water content of more than 70% can no longer be accepted on an ecological basis. |
So what can be done with organic food wastes?
