(Re)assembly corresponds to the repeated process of assembly and includes the reassembly of used, reusable construction/resp. concrete elements with or without preparation to form structural components, structures and structural installations. A combination with new building elements and/or monolithic constructions as well as other materials is possible.

Removal of disassembled building materials for processing into secondary materials.

Recycling (Closed-Loop)
Recovery operation by which waste materials are reprocessed into products, materials or substances for which the purpose is the same as that of the original product.

Refurbish (Renovate / Retrofit)
Act of renewing and overhauling all elements of a building to bring it to a condition that makes it seem as if it is new again, giving it a second useful life.


Re-use is “any operation by which products or components that are not waste are used again for the same purpose for which they were conceived” (Directive 2008/98/EC,pg.9) , and that the process should not require recycling or remanufacturing.
Products are reused, maintaining their original shape and characteristics. Often, this requires the repair or replacement of parts of the product. Reuse is the most desirable treatment method, for it guarantees the highest level of value retention.

Reversible connections
Connections, i.e. physical relationship between building parts, that can be undone without damaging the parts they connect, e.g. bolts, screws, or soft lime mortars. Reversible connections enable complete dismantlement at components' end of life.
