Recyclability

Circular economy, recyclability and the reduction of plastics are themes related to the transformation of the biomaterial industry. In the product development phase of new biomaterials, recyclability of the materials and further utilization of the recycled based materials should be considered. New materials have to be environmentally friendly and preferably biodegradable too.


There are only a few standard methods for testing recyclability of fiber based materials. KCL Laboratory has further developed the testing. Additional new in-house procedures complement the standard methods available.

We have several methods from small scale 25 g up to larger scales of 1.5 kg. At KCL we also have methods for testing usability of the recycled fibers and moreover methods for testing possible stickiness of the recycled fiber.

The small scale KCL repulpability test, corresponding to the Michelmann test, shows how well the fibers can be recycled from the material tested. Our large scale repulpability methods also test the usability of the recycled material. In this test we utilize our 40 liter pulper, our Voith labrefiner and our paper and board making possibilities.

Standard methods available from the KCL Laboratory are the INGEDE 4 Testing of macro stickies and the TAPPI UM 213 Repulpability testing of splicing tape. The latter method can be used for testing also splicing glue or only the biomaterial itself without tape or glue.

We offer our customers support and planning of the lab trial when new materials need to be tested for recyclability. We also assess the usability of the recovered material for possible new product development.
