FiBL has confirmed that our Magaverde bio fibre paper meets the requirements for use in organic farming, following the directive "VO (EG) 834/2007". The sustainable, biodegradable products such as mulch papers and plant pots for agriculture & horticulture as well as packaging are based on process and product developments by GNS.
How can you quickly find out whether an empty gas cylinder is a hazardous waste, and where to put it? In the Information Portal Waste Assessment (IPA) you will find the answer. To ensure that this information is always up to date, it is updated regularly. The waste fact sheet "1605 and 1501 Gases in pressure vessels and used chemicals – gases" was revised by GNS on behalf of the Landesanstalt für Umwelt Baden-Württemberg LUBW and is now online. We have already revised several such fact sheets for the IPA portal.
Magaverde bio fibre products help prevent microplastics in the environment, conserve natural resources, reduce greenhouse gas emissions, are fully biodegradable and can be recycled. A wide variety of products and packaging can be created via paper production and fibre processing processes. Visit our website and become a partner or customer.
We now offer our sustainable products made from regional natural materials of an environmentally sound cascade and circular economy together with partners on our new platform www.magaverde.de.
GNS demonstrates innovative technologies for the recovery of plant nutrients from biogenic waste in the EU project SYSTEMIC.
At five demonstration sites across Europe, the SYSTEMIC project is demonstrating new approaches for recycling bio-waste into energy, secondary raw materials, fertilisers and organic soil improvers. With the FaserPlus plant of the BENAS biogas plant, GNS has been involved as one of the 5 demonstration sites since 2017.
Find out more about the novel nutrient recovery technologies on the PROJECT WEBSITE and subscribe to the newsletters.
These pioneering facilities play a crucial role in the evaluation of new closed-loop technologies. SYSTEMIC will promote the introduction of closed-loop processes for biowaste in Europe.
The GNS-led BioEconomy Cluster project BiogasFaserPlus has been completed. After intensive research on pilot apparatus, the existing plant for digestate treatment system GNS at the BENAS biogas plant Ottersberg was converted into a FaserPlus plant and operated continuously with high operational reliability for many months with 8 to 10 t/h of the fermentation product.
BiogasFaserPlus joint project
After various technical adjustments to the apparatus and settings, the pilot plant for ammonia removal from fermentation residues containing fibres could be operated continuously with a throughput of 2 m³/h. Sample batches of biogas fibres were produced and handed over to the partner Kronospan. The first sample boards were produced from these biogas fibres. The material properties are now being investigated.
Parallel to the test operation of the pilot plant, extensive physicochemical investigations of fermentation residues and factors of influence of technical treatment steps on the fibre quality were carried out. Based on this, the pilot plant will be further optimised.
It is planned to deliver another sample batch of biogas fibres to Kronospan with the optimised pilot plant at the end of August/beginning of September 2016.
On 16 April 2015, the kick-off meeting of the project took place in Halle/Saale at GNS mbH as research network coordinator. The project volume is 2.6 million euros with a duration of 1.5 years.
On 9 September 2014, the final presentation of the project "Material use of lignocellulosic fermentation products for wood-based materials" took place in Cologne. This demonstrated the technical and economic feasibility of the material use of fibre-containing residues from biogas production in the production of particleboard, fibreboard and laminate.
Transporting digestate over long distances can be expensive. The production of mineral fertilisers worthy of transport opens up new ways for cost-effective and low-emission N, P fertiliser management.
At our fermentation residue processing plants, approx. 320 kg/d of ammonium nitrogen are removed from 100 m³/d of fermentation residue. This produces 5.5 m³ of ammonium sulphate fertiliser and 1.6 t of carbonate lime fertiliser. Apart from inexpensive FGD gypsum, no additives are used for this.
Both products are approved fertilisers according to DüMV and are produced with consistent quality.
The ammonium sulphate solution – ASL is suitable as a combined N-/S-fertiliser for all crops. The possibility of foliar spraying is particularly interesting, as no etching effect is to be expected with our product. It can also be used in mixtures with other liquid fertilisers and plant protection products.
Carbonate lime is effective in the long term and is particularly suitable for liming up and raising the pH value of light and medium-heavy soils. It thus supports the nutrient utilisation of other fertilisers. Due to the adherent ASL, the lime contains an additional fertiliser value of nitrogen and sulphur.
