Overview

Mikkeli’s demonstration involves the demolition of two public buildings using circular material management methods, including digital tools: Pankalampi Health Care Centre and Tuukkala hospital. The learnings and experiences of these demolitions will be incorporated into a circular demolition operations model and a generic demolition contract that can be applied in further public projects.

Implementation

• The sites will be scanned and a pre-demolition audit will identify potentially recoverable materials and their characteristics.
• Following  a selective demolition procedure, salvaged materials will be incorporated into a digital databank and construction materials marketplace.
• Use of the marketplace will be promoted to other construction sector actors, private and public, both to offer and to obtain secondary construction materials.

Relevant tools

• 3D Tool for Tracking CDW On-Site
• Databank & Digital Marketplace for Recovered Construction Materials
• Lifecycle CO₂ calculators for soil, concrete and mixed CDW
• Pre-demolition & selective demolition procedure

Overview

A new collection and sorting approach will be tested in a series of apartment buildings in the Peitsari district, owned by the social housing company Mikalo Ltd. The goal is to increase the collection of bio-waste in quality and quantity and simultaneously reduce the bio-waste percentage in the collected mixed waste that is currently disposed of by incineration.

Implementation

• Paper bags will be distributed to residents for the collection of bio-waste, which are less problematic for the new biogas plant in Mikkeli than biodegradable plastic bags which are often currently used
• An information campaign to encourage residents to separate their bio-waste will be implemented
   

Overview

This demonstration action is aimed at optimising the production of biogas from bio-waste collected in Mikkeli, and the development of valuable soil improvement by-products from the nutrients present in the residual streams

Implementation

• A series of mechanical pre-treatment, waste treatment, and end-product optimisation techniques will be explored in a laboratory and pilot-scale
• The biogas produced in the new biogas plant, will be used to run local buses
• Local companies and stakeholders will be closely involved in identifying and developing potential business opportunities deriving from these tests

Relevant tools

• Procurement guide for usage of biogas as a motive power in transportation and logistics services
• Case Study: Promoting the use of biogas in transportation and logistics
• Case Study: Use of biogas reguirements in waste transportation tender
• General guide for organic waste management in public procurement
