Combined Solutions

Developed in Catalonia to deal with agricultural waste: water scarcity; land use; contaminates and alleviate further ecological damage.

Advanced engineering combined with patented and proprietary physical/chemical innovation to reverse the bio-chemical reactions found in agri-food-bio-waste.

Customizable batch or flow modular technologies, turnkey-ready installation, highly automated and monitored 24/7/365.

Compliant with the evolving EU Directives including Nitrates (91/676/EEC), Water (2000/60/EC), Groundwater 2006/118/EC + Green Deal ‘neutral by 2050’.

Sectors

Focus: Helping farms improve their waste management and deliver a return on their investment. Our modular system can be integrated with existing facilities, in different configurations, making it flexible for both small compact spaces and larger farms. It also optimises the feedstock for small or large-scale anaerobic digester systems.

Multiple uses: The technologies can also process high-volume exhausted digestates to release water and solids for reuse as well as integrate into zero-residual operations and the emerging sectors of leachate management (zero liquid discharge) & bio-plastics.

Nutrient Recovery and Reuse

Slurry: A source of organic matter and nutrients needed to enrich soil and promote plant growth – but with increasing volumes, storage and land application – a continuing source of air, soil and groundwater pollution.

Untreated slurry degrades and pollutes.

Time, the longer slurry sits, the more chemical & biological reactions occur = more airborne gases + more nutrient degradation.

Directly applied slurry is an indiscriminate ‘spray and pray’ approach – laying down an equal combination of the good as well as the bad during application periods.

Depending on livestock, 88-97% of your storage is water.

Why store a pollutant?

Our system reverses the bio-chemical reactions occurring in a lagoon, treating waste close to the source, within days of emission.

Separation of dry matter, nutrients and liquids allows for more flexible targeted application at the right times of the year, e.g. soil enrichment in Autumn, plant growth in Spring/Summer, reducing the chance of leaching or exceeding land nutrient threshold allowances.

100% recycled.

Solid fraction

► Low moisture rich organic material, fibrous solids and improved C:N ratio
► Phosphorus (bound to organic matter) + organic nitrogen.

Liquid fraction: 1m3 in = 1m3 recovered:

► ±10% Low moisture rich organic material with high phosphorus
► ±15% Bio-NK nutrients.
►±75% Clean Permeate Water

Process

3 Cycles

A. Mechanical separation of the liquid / solid fractions.

B. Physical Chemical bonding manipulation to release solid and organic material.

C. Membrane technologies to extract H20 & bio-nutrients.

Input – Output

What goes in…

Pig

Water Content: Typically 92-96% of pig slurry is water.

Dry Matter (DM): Contains organic matter (fibrous material, fats, and proteins) and ash (minerals like calcium and magnesium).

Nutrients: Phosphorus and organic nitrogen) are generally concentrated in the solid fraction while potassium and soluble N,P are held in the liquid fraction

Anaerobic Digestion

Reduced Dry Matter: The digestion process reduces the dry matter (DM) content.

Higher Ammonium Nitrogen (NH₄⁺): Organic nitrogen is converted to ammonium nitrogen.

Phosphorus Concentration in Solids: Most phosphorus remains in the solid fraction.

Cattle

Water Content: Cow slurry is less liquid with a water content of 88-92%.

Dry Matter (DM): The higher dry matter content consists mainly of fibrous material from undigested feed and bedding, along with organic matter and some minerals.

Nutrients: Mostly organic nitrogen and phosphorus concentrates in the solid fraction, and potassium + ammonium nitrogen in the liquid fraction

Maths

In 2014, the team set out to find solutions to the very real challenges of water security, land use, contaminants and ways to alleviate further ecological damage to our region.

From the initial R&D through testing, field trials, certification, commercialisation and installation, {nkaptur} delivers cost effective regulatory, environmental and operational solutions to those challenges.

Foot note: why nkaptur? The idea around the word ‘encapture’~ to ‘capture within’  /enˈkæp.tʃər/ ~ ‘c’ & ‘k’ have similar sounds and N, K, P  are our target nutrients, the { } implying within ~ but mainly because the .com domain was available.
