I
have recently been introduced to the duckweed protocol. It is hugely
productive and must be harvested every ten days. The processing
suggested were starts with milling and fermentation convert the plus
thirty percent starch into ethanol which naturally increases the
protein content remaining to over 70%.
Thus
a harvesting system produces a shippable biomass that can then be
milled, fermented and separated into an alcohol stream, a meal stream
and a spent water feed which goes directly back into the production
pond were the contained nutrients are reused.
This
is designed around pig operations and their sewage lagoons, but can
reasonably be used to handle all manure situations.
The
speed of the process is particularly encouraging. In ten days a
hypothetical charge has been consumed into the living lagoon and that
lagoon has produced the matching alcohol and feed protein.
It
is missed here by the author. But tilapia are vegetarians who eat
mostly duckweed or its kissing cousin. Thus in native ditch and bank
agriculture the tilapia consumed the rapidly growing vegetation to
produce a steady stream of protein.
Implementation of
native technique merely awaits proper equipment for grooming ditches
and technology such as this to harvest the duckweed in the ditches.
The added benefit is that grooming entails lifting the muck
accumulation and putting it back up on the bank to refertilize.
PETROALGAE
PROTEIN CONCENTRATE CONFIRMED AS REPLACEMENT FOR
HIGH
QUALITY FISHMEAL IN TILAPIA FARMING BY UNIVERSITY OF IDAHO
STUDY
New
Source of Protein Can Replace Menhaden Fishmeal in a Variety of
Farmed Fish Species
2010
press release
MELBOURNE,
FL — November 4, 2010—PetroAlgae Inc. (OTCBB: PALG), a leading
renewable energy company that licenses its commercial micro-crop
technology globally, announced today that a third party study done by
the Aquaculture Research Institute at the University of Idaho has
found that PetroAlgae protein concentrate (PPC) produced as a
coproduct along with the renewable fuel feedstock by the company’s
micro-crop technology system can replace menhaden fishmeal protein at
levels up to 100% in feeds for tilapia.
“We
are very encouraged by the results of this extensive study because
they point to PetroAlgae protein as a highly desirable replacement
for fishmeal at a time when feed demand is expected to increase
dramatically in the face of limited traditional supply,” said Dr.
Ronald W. Hardy who conducted the study.
The
study also found that PPC would be suitable as a fishmeal replacement
for other farmed fish species. According to the study, tilapia is one
of the largest-volume farmed fish species, and tilapia production is
expected to grow from 2.8 million tons to more than 9 million tons by
2020, requiring 13 million tons of feed (up from 8 million tons in
2010).
PetroAlgae’s
micro-crop technology employs indigenous, aquatic micro-organisms
suitable to local climates and is designed to enable its technology
licensees to produce a cost-effective alternative to fossil fuels as
well as a high-value protein co-product, while absorbing carbon
dioxide from greenhouse gas emissions. Micro-crop farms utilizing
PetroAlgae’s technology are highly productive and grow new sources
of protein locally that are not genetically modified and are
resistant to local diseases. In addition to its uses in the
aquaculture industry, the company expects PPC to be suitable for
nursery swine, poultry, and, ultimately, for direct human
consumption.
Dr.
Hardy, who heads the Aquaculture Research Institute, directed the
nine-week comprehensive University of Idaho PPC study. The study
concluded that:
•
PPC is capable of
replacing fishmeal protein up to 100% in feeds for tilapia, without
the need for amino acid supplementation or other adjustments to the
formulation, and can provide growth performance similar to fishmeal.
•
PPC, when
combined with fishmeal, supported higher fish weight gain than with
fishmeal alone, suggesting a positive synergistic effect most likely
related to favorable amino acid balance in the feed.
•
PPC does not
change the composition of tilapia and does not increase tilapia
mortality rates. Together, these findings indicate that PPC is a safe
feed ingredient with no toxic indications after nine weeks of
feeding.
•
PPC yields
nutrients that are highly digestible, demonstrating significant
potential as a feed component for other farmed fish species.
•
PPC has excellent
suitability for producing low pollution feeds that reduce
environmental contamination in dense aquaculture areas.
“PetroAlgae
micro-crop protein presents a unique and sustainable route to a new,
large-scale protein source to overcome the significant challenge of
replacing fishmeal in aquaculture diets,” said Dr. Hardy.
Because
the fishmeal industry’s main production center is Latin America,
far from Chinese and European consumption centers, fishmeal is one of
the world’s most internationally traded commodities. The
International Fishmeal and Fish Oil Association, a trade body,
estimated that each ton of fishmeal travels an average of 5,000
kilometers to reach its end-user in the aquaculture industry. By
comparison, PPC allows for a shortened supply chain and reduces
business risk, because micro-crop farms using PPC can be sited
locally, close to consumption centers. Therefore, PPC has the ability
to reduce the industry’s carbon footprint, and its steady state
production allows for greater quality control and just-in-time
inventory management.
PPC’s
other environmental benefits include lower pressure on ocean
fisheries, lower risk of zoonotic disease, a positive carbon balance
and a route to renewable fuel that is additive to the food and feed
chain.
“We
are very excited with the findings of Dr. Hardy and his team at the
University of Idaho, said Dr. John Scott, Chairman and Chief
Executive Officer of PetroAlgae. “Their reputation puts them at the
top of their field, and we can proceed with a high degree of
confidence to help our licensees commercialize PetroAlgae protein
concentrate as a high-value replacement to traditional fishmeal in
both quality and environmental impact.”
LemPro
Inc. Project cost, $30 Million
New
source of 61% organic protein produced from local aquatic plant,
35% protein currently in plant is increased by removing the 43%
starch by certified organic process, Ethanol and Lysine are
the by products
Certified
Organic wastewater from process supplies 100% nutrition to the
Aquatic plant growing ponds , No outside nitrogen needed ,
100% close loop with all inputs controlled and monitored as an
industrial process.
Currently
Aquatic plant is use in 30 Louisiana sewage treatment plants with
grow rates well established.
A
very Large Engineering company will be our EPCM contractor
providing Process Engineering , Construction management and if needed
will handle 100% of investment With guarantees, they
are a $6.5 Billion dollar company
Project
has 3 sources of Income:
1.
Bio Electric power produced by burning Rice hulls
from the rice
Mill across the
street from the 580 acre site
2.
3,000 gallon per day Ethanol production
3.
21 tons per day 61% Certified Organic Lemna protein meal
Yearly
Gross income: $13,485,552.00
Yearly
Net before Debt Service: $11,603,292.00
Reasons
why no one has considered this process before:
Ethanol
Industry: Duckweed cannot support a 200 MM gallon plant
and Ethanol Industry does not support organic food production.
Organic
Feed industry: Does not understand the starch removal process By
the simple Certified Organic malt conversion.
Current
Duckweed industry using Duckweed for sewage processing has never
considered growing Duckweed organically without sewage because
the fertilizer cost is too high and no established market.
The
Organic protein market is growing at 22% per year with current winter
shortages.
Today’s
value of our protein meal is $1260.00 per ton, the 21 tons per day of
protein meal production is really a byproduct of our Ethanol system
with all cost being paid by ethanol sales
