Dear Customers & Business Partners,

This year, we once again decided to refrain from sending out Christmas presents.

This year, we gladly support non-profit Educational Center „Heilpädagogisches Zentrum – HPZ gemeinnützige GmbH“, with a financial contribution for an additional escape route, via rescue chute, for the Early Intervention Centre in Pfaffenhofen. This rescue chute can also be used for therapeutical purposes, in order to help children overcome their fears and find joy in exercise.
Fundamentally, the organization supports and fosters children with special educational needs and handicaps.

We would also like to take this opportunity, to thank you for your great cooperation and loyalty throughout this - yet again - challenging year!
NATECO2 wishes you a happy & peaceful Christmas, along with a successful and healthy business year 2023!

05. July 2022 | On July 02nd, 2022, after an unfortunately long break caused by the pandemic, the "Childrens' Day in Wolnzach" was able to take place again.
NATECO₂ supported this event, executed at its home venue, with a contribution of € 500, in order to enable children to enjoy a carefree afternoon, after all the challenges and restrictions throughout the past 2 years.
The free-of-charge gaming fun for our Little Ones featured, besides handicraft work, goal-shooting contests and bull riding, also climbing action and a carousel.

16. May 2022 | As a regular participant of one of the biggest food supplement shows, we were again present with a booth and several highlights this year!
Interested parties, customers and industry experts worldwide were able to catch a whiff of our CO₂-extracted flavors, like Ginger, Pink Pepper, Cardamom or Cloves and get a first-hand impression on the many advantages of our contract extracted raw materials.
The tailor-made extracts (upon request also with Bio/NOP-certification) are free from any kind of solvents, pesticides or heavy metals.
Natural preservation via CO₂-protected atmosphere guarantees a consistent flavor profile.

05. October 2020 | On October 05th, 2020 a new scCO₂ hops extraction unit was commissioned successfully at Hopfenveredlung St. Johann GmbH's plant in St. Johann (Lower Bavaria), upon a building phase of almost three years and - as planned - at the beginning of the harvest season in 2020. read more

01. October 2020 | Food industry trend, towards environmentally-friendly, sustainable, as well as certified and healthy products is ongoing. Efficient defatting of miscellaneous natural substances, via supercritical CO₂-extraction, enables utilization of enriched plant proteins in meat substitute products. Examples include legumes (like soy beans or lupine), nuts/seeds (like cashew, pumpkin), as well as grains (e.g. wheat). read more

01. October 2020 | Worldwide, an increased demand for halal-certified food is reported. Supercritical CO₂-extraction poses an ideal manufacturing process for customers, who focus on halal-certified food products. Within our production process, none of the substances, classified as prohibited, like Ethanol, are applied. read more

20. October 2019 | Exclusively by application of CO₂ high-pressure extraction (> 800 bar) it is possible to extract certain carotinoids, like the antioxidant Astaxanthin, out of Haematococcus pluvialis. Extremely complex implementation of technical process has primarily been established at lab/pilot scale and since 2018 also successfully at production scale. read more

21. February 2017 | Microalgae are capable of producing up to 70% w/w triglycerides with respect to their dry cell weight. Since microalgae utilize the greenhouse gas CO₂, they can be cultivated on marginal lands and grow up to ten times faster than terrestrial plants, the generation of algae oils is a promising option for the development of sustainable bioprocesses, that are of interest for the chemical lubricant, cosmetic and food industry. For the first time we have carried out the optimization of supercritical ... read more

16. July 2012 | Demonstration of NIR inline monitoring for hops extraction and micronization of benzoic acid in supercritical CO₂ -  The use of supercritical CO₂ as solvent for separation processes and chemical reactions is widespread. Many industrial extraction processes using CO₂ consume a huge amount of energy and hence are very cost-intensive. In the past, the duration of extraction was often longer than required for an optimum result. Therefore, an inline monitoring device for terminating ... read more

09. October 2011 | Extraction of Calendula using supercritical CO₂ - Calendula officinalis is a annual or perennial herbaceous plants in the daisy family Asteraceae, native to the Mediterranean region. The plant is 30-50 cm high and attracts attention by its yellow to orange florescence in June to October. Especially the flowers of the plant are important for cosmetical and pharmaceutical applications. The paper presents the benefits and performance extracting dried calendula flowers using ... read more

01. October 2011 | Extraction of active ingredients using supercritical CO₂ - Solvents are usually inorganic or organic liquids which are able to extract other gaseous, liquid or solid substances from a mixture. Moreover inert gases are conceivable as solvents. To be effective as a solvent a liquid like density has to be induced at increased pressures. Especially for the separation of sensitive functional substances for pharmaceutical purposes or for foodstuff the gentle extraction process with supercritical CO₂ is applied ... read more

01. May 2011 | An optimal process is achieved when economic production is combined with high quality standards. But it can require the right kind of expertise to make it happen. Special technology using supercritical carbon dioxide helps to produce extracts from a diverse set of natural products. NATECO₂ GmbH & Co. KG, a company based in the German town of Wolnzach, has built its business around knowing just the right way to implement and further develop ... read more

12. November 2010 | R. Schmidt | EBC Hop Symposium 2010, Wolnzach, Sept 2010 | “Definite non-polar residues could be detected in the resin extract quantitatively” and “Polar active agents remained in the spent hops” (Forster et al.; Poster EBC Congress 1991, Lisbon) Solubility is the most important parameter. But the scenery of active agents has changed since then totally. Therefore the following active agents (fungicides) with actual relevance were monitored during the extraction process ... read more
