This document discusses disinfection and management of hatchery waste. It provides details on various disinfectants and their proper use in disinfecting hatchery equipment and facilities. It also discusses options for managing and treating hatchery solid and liquid waste, including separating waste, composting, rendering into animal feed, anaerobic digestion to produce biogas, and wastewater treatment. The goal is to convert waste into resources and reduce environmental impacts in a socially responsible way.

1. Assignment topic on:
Disinfection
And
management of hatchery waste

2. INTRODUCTION
DISINFECTION:
• It is the application of a germicide to kill all
remaining organisms
• Disinfectants are the chemicals used to kill
microorganisms such as bacteria viruses and
fungi

3. CONSIDERATIONS
Compatibility:
Disinfectants and sanitizers vary in their
chemical structure and pH and may neutralize
each other when used together in the same
environment.
Temperature:
About all disinfectants work more effectively
when temperature is high
pH:
Disinfectants can be either alkaline or acidic
depending upon their chemical structure

4. DISINFECTANTS
Deamy:
Disinfectant-Cleaner-Sanitizer-Viruside-Fungiside-
Dedorant is specifically formulalated for general cleaning
and gross reduction of microorganisms through out the
entire incubation plant
MULTI-PHEN:
It is formulated to be used as a final treatment to kill a
broad spectrum bacteria, fungi and viruses known to be
pathogenic for poultry and to create residual
bacteriostasis for inhibition of microbial regrowth
OXYCLEAN and OXYCLEAN ML:
Are blends of detergents and sanitizers specially used for
egg trays and automatic machines

5. BUILDING AND EQUIPMENT SANITATION
• Washing and disinfection of equipment are a critical
component of hatchery
• All debris must be removed by sweeping, vacuuming,or by
spraying water.
• A high pressure sprayer can be used, but hand scrubbing
will be required if organic material remains or if the
equipment being cleaned should not be exposed to a high
pressure flow of Water.
• A thorough cleaning of the area (setters, hatchers, floors,
chick-go-rounds, vaccinators, etc.)is essential before a
disinfectant can be applied.

6. SETTERS
• Fog a disinfectant after eggs have been set.
• Multi-stage setters should be fogged each
time new eggs are set or transferred.
• When setters are emptied, a thorough
cleaning and disinfection are required. Like for
any other areas, all debris most be removed as
part of the cleaning process.

7. CANDLING AND TRANSFER AREA
• After every egg transfer:
Remove all dust and debris and dispose.
Scrub and wash all wall and floor surfaces with
a detergent.
• Leave to dry.

8. HATCHERS
• The hatcher is the main source of organic contamination in the
hatchery (egg shells, unhatched eggs, dead chicks/poults, fluff,
droppings).
• Conditions in the hatcher (temperature and humidity)
• Strip out the equipment.
• Remove all debris
• Apply water and detergent, Deamy solution or foaming
solution before scrubbing all parts of the Hatcher (walls, floor,
and ceiling).

9. Contd..,
• Pressure wash.
• Rinse thoroughly.
• Remove excess water and reposition the
equipment
• Apply a disinfectant finally MULTI-PHEN or IX91
• Warm up the hatcher to help dry the interior
• Make sure that the outside of the hatchers is also
cleaned.

10. WATERLINE SANITATION:
• Dirty water lines may help transmit disease agents.
Therefore, waterline sanitation is important.
• It is important to use proper products to clean
waterlines and to follow the manufacturer’s
recommendations.
• Chlorine is effective as a sanitizer at 3 to 10 ppm and
iodophors at 12.5 to 25 ppm.

12. Waste management:
• Waste treatment can occur both on-site (at the
hatchery) and off-site (at a treatment or
processing plant). Ideally, some pre-treatment
of waste should occur on-site. Solid waste
should be separated into eggshells, solids, and
liquids and placed in different recycling
trajectories. This reduces pathogen load and
creates options to get the most from your
waste.

13. Contd..,
• There are various options for separating solid
hatchery waste into solids and liquids, such as:
• inclined screens with presses
• centrifuges
• multi-layer filters using gravity
• conveyor belts and rollers etc. each ranging in
ability to capture solids

14. ALTERNATIVES:
• General solid waste can be recovered into
value-added products through composting,
rendering, and anaerobic digestion. These
options are expanded upon below.
• It is worthy to note that many countries have
regulations for processing animal by-products .
Be sure to check local requirements or ship
hatchery waste to an appropriate government-
approved facility.

15. REDIRECTING TO ANIMAL FEED
• One option to recycle hatchery waste is to send it to a
feed processing plant. To make a protein, fat, and
nutrient-rich animal feed that is also safe, hatchery by-
product meal must have a pathogen-free status.
• This is possible through autoclaving or extruding
followed by temperature disinfection and drying, or
pressure boiling and drying.
• Waste must also be heat-treated to kill a protein called
avidin found in egg whites (responsible for eye,
locomotive and reproductive problems).

16. COMPOSTING:
• Composting facilities use either a batch or continuous
system, depending on how often input materials are
received.
• Batch systems accept material at set intervals per year
while continuous systems accept a set volume of
material daily.
• Poultry litter is more commonly associated to batch
composting due to all-in all-out flock cycles, whereas
hatchery waste is removed multiple times per week and
is more suitable for continuous composting.
• By combining forces, hatcheries and poultry growers
could support a continuous composting system.
• It takes about eight weeks to generate compost fit for
field application but further curing would improve
compost stability for soil amendment and fertilizer use.

17. Contd..,
• In general, on-site in-vessel composters have a
quicker turnaround time. Named "DiCom" is a new
composting vessel that converts solid waste into
biogas and stable compost for agricultural
application.
• Finished compost can be used internally, donated,
or sold. The retail price of compost depends on its
quality, consistency, and market demand.
• It may very well cost less to build and run a poultry
litter and eggshell compost facility than it does to
send waste to disposal grounds.

18. ANAEROBIC DIGESTION
• For large-scale hatcheries, an on-site anaerobic
digester system efficiently creates biogas from
methane, which can be used for in-house
power generation, as well as bio-solids, which
are saleable as a high quality fertilizer.
• The process of anaerobic digestion eliminates
pathogens and is already established in treating
human effluent and slaughter plant waste.

19. WASTEWATER TREATMENT:
Hatchery wastewater can be sent to wastewater
treatment facilities. Or, it can be treated on-site
using batch or continuous anaerobic digesters.
First, waste needs to be cleared of non-
biodegradable materials (glass, plastic, and
metals) and then shredded to maximize
digestion speed.

20. Contd..,
• Various options exist depending on the concentration
of bio-solid content:
• covered lagoons (suited for warm climates), fixed bio-
film tank for quick turnover, complete mix in silo tanks,
and plug flow digesters.
• If hatcheries use lagoons to dispose of wastewater,
integrated aquaculture could be an attractive option.
• After reducing the fat and solid content, a series of
ponds can host algae, zooplankton, molluscs, and
ornamental fish while cleaning water for irrigation.

21. SOCIAL RESPONSIBILITY :
• Any efforts to reduce waste dumping or
untreated hatchery disposal directly reduces
greenhouse gas emissions, groundwater
contamination, and pathogen and phytotoxic
release into the environment.
• Converting waste into resources will enable
the poultry industry to achieve sustainability
and social responsibility targets.
