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.

Impact of BOC on Viscosity

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.



II. DIGESTATE PROCESSING1. THE ISSUE : REGIONAL CONCENTRATION OFMANURE AND DIGESTATE PRODUCTION

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!
