WASTE ORIGIN: General Operations
WASTE TYPES: Waste Food and Food By-products
WASTE REDUCTION AND RECYCLING METHODS:
- Reduce landfill and wastewater treatment
costs by decreasing waste material and by-products in production
processes:
- Use brooms and scrapers
to clean floors while they are dry before washing down with
water;
- Use high-pressure spray washes
during cleanup to conserve water;
- Dedicate mixing lines
to certain products to reduce changeover cleanups;
- Minimize spills and leaks
on the production line to prevent raw materials from becoming
wastes.
- Use food by-product as an animal
feed:
Advantages over composting
or landspreading include: fed to livestock in original form
(check with local animal health authorities to see if permit
is required), fed in both liquid and solid form, and can be
fed all year regardless of weather conditions.
- Composting by-products creates
useful soil additive called humus with the following benefits:
- Low transportation costs
from on-site composting; volume and weight of wastes can be
reduced up to 40 percent;
- Low capital investment
is required since composting is a batch process using a simple
pile and windrow system for biological breakdown;
- Useful for seasonal processors
like canneries whose wastes may be available for only a short
period and not acceptable for livestock producers as feed;
- Humus can be stored without spoiling;
raw food by-products cannot.
- Landspreading incorporates
by-products directly into the soil with the following benefits:
- A separate on-site compost facility
is not necessary;
- The finished product does not
have to be stored;
- Finished product does not have
to be transported; it becomes a plant nutrient in
the soil.
