Professional organic waste reduction system

Organic degradation

The organic degradation of household waste naturally varies depending on the type of waste, but overall, our tests show a reduction of 75% to 85% in mass, which represents a gain of 80% to 90% in terms of volume. (depending on the product to be degraded)

1. An approach to biological functioning:

The ratio of surface area to volume is one of the fundamental characteristics of bacterial functioning.

This interface principle is at the heart of our biodegradation system, where the processing time for household waste must not exceed 24 hours. (Role of the interface)

It is through this interface that exchanges between microorganisms and their environment take place, in this case between enzymes secreted by bacteria and organic matter to be broken down. The greater the renewal of this matter on the bacterial bed, the greater the exchanges will be and, consequently, the faster this matter will be “digested.”

Our system enables this acceleration. Structural role of our nesting method: Our method of implanting specialized bacterial colonies on a mineral substrate allows for effective and protected nesting, which increases the resistance of microorganisms to external agents. Less sensitive to chemicals, temperature variations, and other accidental mechanical stresses, our bacteria are more resistant and result in better compost homogenization.

2. Nutritional requirements

Bacteria are living organisms that need to find all the elements that make up their cellular structure in their environment, i.e.: C, H, O, N, P, S, etc. These elements are found in the form of molecules of varying complexity, such as sugars, starch, cellulose, proteins, fats, hydrocarbons, etc., which are naturally present in organic matter. 3. Mode de croissance des bactéries :

This mode is exponential.

• 1st Latency phase:

Bacteria acclimatize to their environment and synthesize their first enzymes.

• 2nd Exponential growth phase:

Bacteria reproduce very rapidly.

• 3rd Stationary phase:

Reproduction stops, bacteria live off their nutrient reserves. (Dynamic phase)

• 4° Decline phase:

The number of bacteria decreases rapidly (aging phase). A slowdown in the stationary period is then observed; the aging of the bacteria inhibits growth and ultimately leads to a breakdown in degradation.

In order to avoid this decrease in yields, the biomass should be rejuvenated to ensure constant and linear degradation.

Technically, for a device designed to process 200 kg of household waste per day, this maintenance is reduced to a daily addition of 25 to 50 g of biological product.

3. Conclusions :

3. Conclusions:

• The process can be divided into three reduction phases:

1. Volume reduction: between 1 and 4 hours depending on the load

2. Moisture reduction: between 4 and 10 hours depending on dryness

3. Mass reduction: 10 to 12 hours

including stabilization and homogenization, variable depending on the nature of the waste.

• With the consortiums developed by Natura Viva, the following was observed over a complete 12-hour cycle:

Volume reduction > 90%

Mass reduction > 90%

Uniform moisture content at the end of the process, with reduction ejection every 24 hours.
