Waste can be broadly categorized into organic and inorganic fractions.
Four significant components of this organic, biodegradable stream
are from food preparation, agricultural production, livestock manures,
and municipal sewage sludge.
IBR has succeeded in effectively processing all of these waste streams;
rapidly and economically converting them to marketable forms within
one week, creating uniform and consistent products for commercial
agriculture, leaving no organic residues still to be processed or handled.
Organic Waste Concerns:
1. Food Waste
Organic waste from food sources includes vegetables, fruits, grains,
meats, fish, dairy products, etc., and constitutes some 18% of the
typical municipal organic waste stream. An average of 1 kg per person
per day of organic waste is produced, originating from households,
wholesalers & processors, restaurants, and institutions.
Urban centers are the major generators of organic food waste and
as a result have the largest disposal problems. The following are
typical municipal production rates:
| City |
Organic Waste Generated (tonnes
per day) |
| Metropolitan New York |
11,000
|
| Greater Toronto |
5,800
|
| Greater Vancouver |
2,700
|
The costs of waste management planning and implementation continue
to increase. Current waste disposal options (landfills, incineration, waste to energy and
composting) have their limitations and their own environmental problems:
Landfills
- Nearing capacity
- Toxic leachate & water issues
- Greenhouse gas emissions
- Odours
- Vector attraction
- Public resistance to new sites
- Limited land available
Existing landfills are nearing capacity and siting new landfills
is an ongoing challenge, along with high development costs. Transporting
waste to more remote places for disposal is a temporary and expensive
solution for many urban centers yet municipalities have been slow
to introduce new environmental technologies.
Incineration
- Residue problems
- Air pollution
- Destruction of nutrients and organic matter with little to no recovery
- Concentration of heavy metals
- Odour emissions
- High energy usage
Composting
- Large area required
- Long processing and curing time
- Ineffective pathogen removal
- Vector attraction
- Inconsistent and bulky, low value product
- Concentration of contaminants
Waste to Energy
- Uneconomic residual
- Marginal economics
- Sustainability of process
- Susceptible to seasonal weather changes
While recycling and recovery programs for inorganics such as paper,
glass, metals, and plastics have been implemented successfully, biodegradables
continue to threaten the environment as the ratio of organic to inorganic
materials in landfills increase.
2. Agricultural Waste
Nitrogen, phosphorus and potassium (N-P-K) are needed for healthy
plant growth. However, today's agricultural practices rely on water-soluble
minerals to provide a complete source of nutrition to plants by way
of chemical fertilizer inputs.
Sufficient evidence demonstrates that conventional crop management
practices are reducing soil biological diversity year by year, destroying soil structure,
and increasing disease pressure. As this diversity decreases, the
need for more nutrients increases, possibly explaining why today 300%
more chemical fertilizer is applied than 40 years ago to achieve the same
yield. In addition, the increased occurrence of major plant diseases
has been linked to the reduction of biological activity in soils and
the consequent unhealthy and susceptible crops grown in them.
Earlier it was not possible to integrate organic fertilizers into modern
industrial agriculture equipment and practices. Specialty organic
products have made significant inroads, but have been unavailable
to commercial growers because of insufficient production, inconsistent
supply, and instability of product. While compost is widely available,
its variable quality and lack of scientific data has resulted in
poor performance confidence. In addition, conventional crop production
methods demand physical forms compatible with modern equipment.
The potential for contaminants in composts, whether pathogens
or inorganic waste materials, the volumes required for plant response, and the inability
to transport over great distances, has created resistance in the
marketplace.
3. Livestock Waste
Recently, there have been many environmental and health concerns
over the disposal of agricultural manures from industrial farms.
High concentration of livestock waste in farm areas has resulted
in contamination of aquifers and wells that supply drinking water
to surrounding communities. Improper disposal of manures has been
linked to numerous deaths and illnesses due to:
- High concentrations in small areas
- Presence of deadly pathogens (E. coli, etc.) that can poison
drinking water
- Land spreading that pollutes streams and aquifers with nitrates and phosphates
4. Municipal Sewage Sludge
In many jurisdictions municipal sewage sludge does not pose the same
risks as livestock waste, as it is usually treated before disposal,
however, some real concerns and public perception problems still remain over the safety of the final product
due to:
- Concentration of heavy metals
- Pathogens
Conclusion
Governments, producers, and society need a waste disposal solution
that is economic, and efficient, and that doesn't add further environmental
pressures to the growing world. Practical solutions are required to
the problems caused by intensive farming practices, and the increasing
dependency on agro-chemical inputs.
For those seeking new ways to cope with increasing volumes of biodegradable
waste and sludge, IBR offers a unique and effective solution.
The Solution
Until now, traditional methods of treating biodegradables have been
unable to effectively process waste containing high quantities of
contaminants. IBR's EATAD technology effectively processes wet organic
waste, reducing the negative environmental impacts created by decomposing
organic matter in landfills. IBR's conversion process is remarkable
in its ability to continually and successfully process organic waste
materials with up to 10% non-biodegradables in its mix. The resulting
products are clean, uniform, and pathogen-free for use in commercial
agriculture.
Use of IBR's products will:
- Act as a natural soil fertility builder, improving
soil quality year after year with annual applications
- Reduce fertilizer and fungicide usage
- Reduce nutrient leaching and increase nutrient use efficiency
- Increase crop yield and quality
- Decrease crop management costs
