Infrastructure / Biological Restoration

Biological restoration of soil and water systems.

One biological platform, two domains. Patented microbial methods, applied in the field across Europe since 2013, on landfills, mining sites, embankments, and wastewater systems.

Soil Systems

We restore biological function in degraded soil, landfills, mining sites, embankments, contaminated farmland. K2 engineered compost reactivates the soil's own biology rather than masking the damage.

Water Systems

The same biological platform applied to water, aerobic tanks, constructed wetlands, bioreactors, stagnant water bodies. Restores dissolved oxygen, eliminates odors and sludge.

The Biological Platform

Reactivate the biology, don't replace it.

All organisms used are naturally occurring and non-pathogenic. Once established, they remain active in treated environments for over ten years.

01

Introduce

Targeted microbial consortia delivered through K2 engineered compost or aqueous cultures.

02

Transform

Pollutants neutralized, nutrient cycling re-established, soil structure or water chemistry rebuilt.

03

Regenerate

Vegetation establishes, aquatic life returns, the system maintains itself with no further input.

Protocol BT22-CM

Restoration from waste.

Municipal sludge and organic waste are a disposal problem for utilities. We take them in, process them, and turn them into the product we use to restore soil health.

01 / Input

Waste reception

Municipal sewage sludge and urban organic waste, accepted under utility contracts.

02 / Transform

K2 bioprocessing

Controlled microbial inoculation and stabilization. Output is K2 engineered compost, patented and field-validated.

03 / Output

Active restoration

K2 deployed on landfills, mining sites, embankments, degraded farmland. Soil function returns within 1-3 years.

Featured project / SUH-01

Suhodol Municipal Landfill

One of our most documented K2 applications. A long-term reclamation of a large municipal landfill, from active leachate and zero vegetation, to a stable, self-sustaining cover.

2010
Site assessed
No vegetation. Active leachate. Heavy contamination.
2013
K2 first applied
Microbial inoculation. Pioneer vegetation introduced.
2023
Stable cover
Self-sustaining vegetation. Soil indicators improved.

Soil recovery timeline

pH, organic matter, and nutrient balance return to functional levels within one to three years of treatment.

10+ yrs
Long-term stability

Microbial communities established by K2 stay active in treated soil for over ten years.

13 yrs
Field-validated track record

All results are from documented field work, mines, landfills, roads, water systems.

EU Consortium Partner

Implementation and demonstration partner across Horizon Europe, LIFE, CBE JU, and Mission Soil.

We co-develop work packages on land reclamation, ecosystem resilience, and circular bioeconomy integration. We scale from lab-tested processes to field demonstration at TRL 5 to 7.
