Cellulose products such as newspaper, cardboard, wax-board and now glassine liner can be transformed into new resources such as insulation, hydroseed, the basis of hydro mulches, oil spill kits and more.


Glassine liner is the most recent addition to the Enviroflex cellulose offering. This liner is a fine quality, high density paper with a silicon coating on one side. It is used in the label industry as the backing for label printing.

The silicon allows the labels to be removed easily from the roll to be applied to a wide array of products from water bottles to beer cans and dairy packaging.


Most simply put – “The definition of cellulose is the main substance that makes up the cell walls and fibers [fibres] of plants”. A more scientific explanation – “A polysaccharide, (C6 H10 O5), that is composed of glucose monomers and is the main constituent of the cells of walls of plants. It is used in the manufacture of numerous products including paper, textiles, pharmaceuticals and insulation”. (www.yourdictionary.com)

While cellulose is a natural fibre, it can go through numerous processes to transform it into many different products and applications. Timber, bamboo and sugar cane are cellulose, cotton, linen, hemp and jute are also cellulose. There are many resulting products from these cellulosic bases. For example, cotton, linen and viscose textiles, newspapers, paper and cardboard, and various wrappings – food and non-food grade, are all made from cellulose pulp. Note that some industrial processes to transform these cellulosic products are not environmentally friendly, particularly in the textile industry.

As cellulose is a precious resource being harvested from our environment, it is crucial that we keep it in circulation for as long as we can, rather than burying it in landfill.

Enviroflex processes a variety of cellulose-based waste products such as –
• Newsprint
• Cardboard
• Wax board
• Glassine liner

The Enviroflex process is to collect the waste cellulose, sort it and then process it through shredders and hammer mills to “fiberize” it, breaking it down to be used as a feedstock for other products. The term ‘feedstock’ refers to a raw material that is supplied as a component part of an industrial process.


This is the most traditional form of cellulose used for insulation and hydroseeding. As newspaper production decreases with the reduction of demand as people turn to digital platforms, supply is unstable. It does provide a reasonably cost-effective insulation solution that requires topping up every 7 to 10 years, dependant on the environment in the roof.

Enviroflex provides this processed newsprint to other industries as well such as those supplying components – brake pads for trains. The newsprint serves as the feedstock to which other chemicals or solutions are added to impart the required performance criteria.


The paper base of this liner is ethically sourced and has Forest Stewardship Council certification, meaning that the cellulose is harvested with environmentally sound and sustainable practices. Once the liner is parted from the labels when applied to a wide array of products, the waste liner rolls are collected to be processed to take the cellulose back to its original fibrous state. This soft and lofty fibre is highly suitable to create new products with different end purposes, extending its life as a useful resource and keeping it out of landfill.


Cardboard supply has increased exponentially with the surge in online shopping and was fuelled further by COVID-19 which has driven huge online sales growth. Processed cardboard is used for hydroseeding, hydro mulch, in a mix. Cardboard is commonly recycled now to make new cardboard boxes.


The combination of plain and waxed cardboard creates a solution for marine oil spills, soaking up the oil from the water’s surface.
