Circular economy specification projects

The fast, flexible drawing up of specifications brings advantages for the circular economy, for example by building a network of potential customers and partners.

Standards work

Reference model for the design and application of zero-waste processes

The overarching objective is to establish a method to describe the zero-waste process. In detail, the DIN SPEC will define a reference model for providing evidence of exemplary waste disposal practice based on defined, documented and verifiable criteria.

DIN SPEC 91436

Open Source Hardware

This DIN Specification will lay down requirements for open source hardware, in particular which (technical) documentation is to be made openly and freely accessible so that the freedoms formulated in the definition are guaranteed.  The specification defines the term “open source hardware” and other terms necessary for understanding this subject.


Sustainable dismantling and recycling of wind turbines

This specification lays down requirements for the preparation and dismantling, and recycling of wind turbines, taking into consideration cost aspects and environmental and safety aspects. The standards project also includes instructions for sustainable handling of the material flows and their recovery, recycling and disposal. 


Recycled pulps - Direct determination of stickies by means of near-infrared measurement

This specification will specify a test method for determining adhesive contaminants directly on a laboratory sheet or on a sheet of paper using infrared measurement. It is applicable for recycled pulps and recycled paper.


Fine Bubble Technology - Fine Bubble Induced Gas Flotation Devices - Installation and Operation

This standard will specify the proper installation, operation and troubleshooting of fine bubble induction equipment for flotation in wastewater and other liquids.

NOTE: Equipment for induction of fine bubbles for flotation can be used for treatment of waste water and other liquids such as: spent metalworking fluids (cutting fluids, washing water) - waste water from the paper industry - waste water from food and beverage plants - waste water from the oil and gas industry - surface water (including sea water).

DIN SPEC 54789

Specification for sustainability assessment of start-ups Criteria and method for the sustainability assessment of venture projects and young enterprises

This standard will establish requirements for assessing the sustainability potential of start-ups. The standard is aimed at founders and start-ups as well as capital providers and start-up support institutions.

DIN SPEC 90051

Quality assurance of recycling products from dry toilets for use in horticulture

This standard will set requirements for the quality and safety of recycled fertilisers from source substrates of human origin. These requirements are defined by a multi-criteria approach and based on a risk analysis.

DIN SPEC 91421


The aim of this project is to use tire manufacturing as an example of configuring the needs of the circular economy.

More information

Within this project DIN is responsible for drawing up specifications and, in addition to researching standards relevant to the circular economy, is responsible for implementing project results in a new specification and/or for bringing the results into existing European and international standards work.

This research project involves the development and practical application of an evaluation method. The main objective of the cooperation is the development of solutions to meet general challenges of the process industry in connection with non-technological barriers to trade. These include regulatory bottlenecks, but also a lack of European standards and specifications. Legal barriers are to be identified that hinder the innovation process and the increase of resource efficiency in various areas.

More information

DIN is responsible for researching relevant standards and specifications, and assisting in the planned European standardization activities. This will improve exchanges among the various sectors and enhance the participation of industry in the standardization process.
