Eco Straw Pulping

From straw to unbleached or bleached pulp 

Eco Straw Pulping can be installed as an independent unit to produce marketable unbleached or bleached pulp, or can be retrofitted to paper mills (close to straw production) to produce Paper, different types of Packaging or tissue from straw, some of which will need to be mixed with high grade recycled pulp or virgin pulp.

The mini mills produce pulp but also valuable by-products with different applications, one of which being soil conditioner or fertiliser that can be used by farmers.

The capacity of these mills can vary from small to medium, 10 to 400 tonnes unbleached or bleached pulp per day, the straw being supplied within a 50 miles radius.

From straw to unbleached un-cleaned straw pulp – Project I

Eco Straw Pulping can have a small or medium capacity and be installed on or near the farms where the straw is produced and transform the straw into an unbleached un-cleaned paper pulp.

The unbleached straw pulp can be used for kraft paper or moulded packaging.

Our small demonstrator is currently producing small quantities of this pulp, and a larger capacity demonstrator mill is planned to start producing in 2018.

 

From straw to bleached straw pulp – Project II

The Mini Mills producing bleached straw Paper Pulp and valuable by-products.

The by-products can have different applications, one of which being soil conditioner or fertiliser that can be used by farmers, but also as raw material for moulded packaging when mixed with other fibres, and for some other valuable applications.

The Mini Mills can have a small or medium capacity and can be installed on or near the farms where the straw is produced.

For higher capacities, NER’s concept is to divide the process in two parts:

– One part producing the unbleached un-cleaned pulp, near the source of straw

– the second part being a central unit processing the unbleached un-cleaned pulp to transform it into a cleaned and bleached pulp or directly to paper.

This avoids transport of bulky straw. It’s a much lower volume of pulp that is then transported.

Bleached straw pulp is currently available only in very small quantity and a larger scale production is planned to start production in 2018.

The advantages of this innovative process are:

  • No more transport of bulky straw

  • Much less energy used compared to existing processes

  • minimum 30% less investment and operational costs

  • no Waste, no odour

  • The Mini Mills are designed to be farm located

  • The process and equipment can be operated easily

  • Capacity can be adapted to the size of the farms

  • The by-product can be sold as a soil conditioner, fertiliser or as raw material for moulded packaging.
