Ultrafiltartion Membrane Process

In today’s nutraceutical and functional food industries, innovation and sustainability are more than trends-they’re essential. Greenvit® PureGreenLineTM revolutionizes botanical extraction with a cutting-edge, eco-friendly approach that meets the highest standards of quality and purity.

Pure Technology

Pure water-only extraction

Designed for forward-thinking manufacturers, this breakthrough process provides premium extracts that meet the growing demand for clean label, high-performance ingredients.

Berries harvesting & freezing

PureGreenLine™ process

Steps before berries arrive at the Greenvit facility

1. Harvesting

Our berries are sourced from local European farmers. Carefully selected varieties of berries are harvested when mature, in August and September.
2. Freezing

Initially cleaned berries are being frozen and transported to the Greenvit Extraction Facility.
3. Storage

Frozen fruits are stored at -18°C to -25°C in airtight packaging with controlled humidity and air circulation to preserve quality and ensure readiness for filtration.

National Recovery and Resilience Plan

Sustainability and Innovation in Nutraceuticals

Technology
Modern, sustainable and environmentally friendly production technologies

Thanks to the funds obtained under the National Recovery and Resilience Plan (NRRP), we have implemented a project that enabled us to introduce modern, sustainable, and environmentally friendly production technologies. As a result, we have expanded our offer to include standardized plant extracts with exceptional specifications, meeting the growing needs of the food industry in Poland and international markets.
Quality
High and consistent content of active compounds — organic and conventional quality

The new product line was developed using innovative processing methods applied to domestically sourced fruits and plant raw materials, including, among others, chokeberry, black elderberry, haskap berry, wild blueberry, milk thistle, and hops. The technologies employed allow for the production of extracts with a high and consistent content of active compounds, available in both organic and conventional quality.
Sustainability
Eco-innovative solutions combining top quality, raw material safety and environmental responsibility

The implementation of the project has enabled us not only to significantly diversify the product portfolio of Greenvit Sp. z o.o., but also to introduce eco-innovative solutions that combine top quality, raw material safety, and environmental responsibility. This represents another step toward building a modern, competitive, and sustainable economy, while also addressing the challenges of today’s food industry.

Project No.: DOPI-84000-OR1000023/22, co-financed by the National Recovery and Resilience Plan.

Process

From berry to final product

STEP 1
Extraction with reverse osmosis water

The cleaned berries are transferred to a mixing tank, where they are combined with reverse osmosis water. A high-powered propeller creates a vigorous swirling motion, efficiently extracting the juice and valuable compounds. The separation process utilizes centrifugal force to divide the liquid extract from the pulp. The remaining pulp is not discarded—it’s repurposed to minimize waste, emphasizing our zero-waste production philosophy.

Sustainable Energy

The entire process is powered by photovoltaic energy, ensuring a minimal carbon footprint.
STEP 2
Microfiltration membranes process

The first filtration step employs ceramic multi-channel membranes designed to capture microscopic impurities such as germs and solid particles. This step ensures the liquid extract is microbiologically stable and safe for further processing. The use of low-pressure filtration technology not only reduces energy consumption but also minimizes the carbon footprint, reflecting the Pure Green Line’s commitment to sustainability.

Filtration area

Optimized filtration area minimizing operational cost – low pressure process, low energy necessary for filtration, smaller carbon footprint.
STEP 3
Ultrafiltration membranes process

The extract is further refined using nanometer-scale membranes to isolate and concentrate essential organic compounds like polyphenols, polysaccharides, and oligosaccharides. These compounds are known for their health benefits, such as antioxidant properties and digestive support. The process takes place at a low temperature to protect the delicate polyphenols and polysaccharides. By removing unwanted elements while retaining these valuable nutrients, the process produces a superior-quality extract rich in active ingredients.

Zero waste

Sugars from this filtration can be reused as natural sweetener in the food industry.
STEP 4
Concentration by reverse osmosis membranes

In the final filtration stage, a reverse osmosis membrane separates water molecules from residual sugars and other impurities. The purified reverse osmosis water is recycled back into the system, creating a closed-loop water cycle that drastically reduces waste. This step embodies Greenvit’s dedication to conserving natural resources and achieving sustainability in every production cycle. Meanwhile, sugars removed during this step are repurposed as natural sweeteners, contributing to a zero-waste initiative.

Water reuse

Recycled, purified reverse osmosis water is reused for extraction on fresh berries.
STEP 5
Drying & packing

In the drying process additional fiber is added to the liquid extract, enhancing its nutritional profile. This step introduces a natural source of fiber, creating a prebiotic effect that supports gut health and contributes to the functional benefits of the final product.

Packing

Final extract in powder form is packed in bags of desired volume.
