BS EN 17351:2020,Bio-based products – Determination of the oxygen content using an elemental analyser.BS EN 17351:2020 pdf free download.
Bio-based products from forestry and agriculture have a long history of application, such as paper, board and various chemicals and materials. The last decades have seen the emergence of new bio-based products in the market. Some of the reasons for the increased interest lie in the benefits of bio-based products in relation to the depletion of fossil resources and climate change. Bio-based products may also provide additional product functionalities. These developments have triggered a wave of innovation with the development of knowledge and technologies allowing new transformation processes and product development.
It is important to understand what the term bio-based product covers and how it is being used. The term bio-based means derived from biomass Bio-based products bottles, insulation materials, wood and wood products, paper, solvents, chemical intermediates, composite materials, etc ) are products whicl are wholly or partly derived from biomass. Itis essential to characterize the amount of biomass contained in the product by, for instance, its bio-based content or bio-based carbon content.
The bio-based content of a product does not provide information on its environmental impact or sustainability, which may be assessed through LCA and sustainability criteria. In addition, transparent and unambiguous communication within bio-based value
is facilitated by a harmonized framework for certification and declaration.
This document has been developed with the aim to specify the method for the determination of oxygen content in bio-based products using an elemental analyser.
