WHO WE ARE
Renew Sources was founded in 2007 and
offers the below products and services:
Solid knowledge on all aspects of renewable energy
production,
Support to biogas plant operators for optinization of
economics,
Speciilised products for technical and biological improve-
ments,
Technology for digestate processing.

I. BIOORGCANIC CATALYSTS (BOC)
Bio-Organic Catalysts (BOCs) are built upon the bio-catalytic capabilities of a
fermentation supernatant, derived from yeast and a balanced composition of
other active ingredients.
BOCs contain no bacteria, or active enzymes, but stimulate the vitality of
indigenous microorganisms along with releasing its valuable nutrient source.
The functional mechanism of BOCs is attributed to molecules consisting of
both a hydrophobic and a hydrophilic element. They attach to components
such as;
■ Organic Feedstocks
■ Oxygen
■ Foul Gases
■ Byproducts of decaying
organic matter

BOCs are produced by Bio-Organic Catalyst, Inc.

OPTIMIZING ANAEROBIC DIGESTION SYSTEMS
BOCs offer substantial improvement in anaerobic digestion,
BOC has shown, in municipal, industrial and agricultural anaerobic
digestion systems, that they act on the total volatile solids and total solids
components, providing higher reduction rates over baseline values.
BOC lead to a faster increase in methane-forming Bactria,
Sludge quality is enhanced due to more complete digestion and sludge odors
will be greatly reduced.
BOCs improve the economics of biogas production.

CASE STUDY: RICHWOOD WASTE WATERFACILITY
In August 2014, the formation of a mat of grease
which was 4-6 Ft thick was observed.
The addition of BioOrganicCatalyst began early
September.
This was stopped after 10 days as the FOG cap was
drastically reduced.
BOC Benefits:
1. Allows increased VS Loading while
maintaining increased biogas yields.
2. Improves dramatically biogas production
in underperforming Anaerobic Digesters.

BOC APPLICATION IN BIOGAS PLANTS IN GERMANY
BOC were tested in 5 agricultural biogas plants in
Germany:
The operations are of a size between 250 kw el. and 3
MW el.
Tests were started in summer 2016.
The daily dosage is 250 ml/t Organic Dry Matter (ODM)
fed.
Key Findings:
Fast improvement of homogeneous mixing
of the fermenter content.
Better degradation of organic matter.
Improved viscosity resulting in decreased
electricity consumption for mixing,
Reduction of floating layers.

WHAT BIOGAS-PRODUCERS IN GERMANY SAY:
I think we do the right thing! The pumps no longer knock.We see significant less
residual gas in the digestate.
We see improved viscosity and need less electricity for mixing.
The massive swimming layer in the post-fermenter has been dissolved and does not emerge again.
We were able to turn off a stirrer and a level indicator returned data after 2 years.

APPLICATION OF ECOSYSTEM PLUS
Application:
• EcoSystem Plus® can be fed directly into the
biogas fermenter,
• For biogas plants, a daily dose of 250 ml / t
ODM (organic dry Matter) has proved its
worth.
• Individual dosages are used for the
decomposition of floating layers and
sewage treatment plants.
• EcoSystem Plus® is non-toxic.

2. APPROACHES FOR DIGESTATE PROCESSING

3. MECHANICAL SEPARATION: DRY AND LIQUID PHASE
By mechanical separation the digestate volume can be reduced by about 10%. Furthermoreeffective separation is the precondition for most digesttate processing technologies.

4. BIOLOGICAL TREATMENT
Biological Treatment is widelyspread in Wastewatertreatment plants.
Treating Manure and Digestate with significantly higher organic loads is much more difficult and requireshigher aeation-tank-volumes thancurrently often applied.

5. VSEP RESONATING DRIVE SYSTEM
The VSEP-System is successfully applied in several manure and digestate processing plants in Europe, USA and Korea.
The Flux-Rate depends on the Dry-Matter content of the digestate/manure to be processed. Effective Pre-treatment is crucial!
