SUstainable Projects – Sustainable building materials

LoBi – Low CO2 binders replacing traditional cement

Cement production accounts for 8% of global emissions, most of which comes from the process of creating cement clinker, an intermediate material in the production of Portland cement. Additionally, in ternary binder systems, the use of calcium aluminate cement is also a significant contributor to emissions.  

To lower the emissions related to construction, the LoBi SUPER project aims to produce new binders, in which Portland cement and calcium aluminate cement are replaced by supplementary cementitious materials, such as ground granulated blast furnace slag, a byproduct of steel manufacturing. 

Fossil-free raw materials for adhesives

Most contemporary adhesives based on traditional raw materials are based on fossil-based polymers obtained from petrochemical processes. Adhesives are used in practically all areas of life, from the buildings we live in to the products we use and consume on a daily basis. 

This is an area where we at Kiilto would like to improve our processes, to not just make our processes more sustainable, but to provide alternatives for our partners to use sustainable binders in their products as well, without having to compromise on strength or reliability.  

Functionalised lignin 

As a byproduct of cellulose extraction processes in the paper industry, lignin is the most abundant bio-polymer available to us. Currently, most of it is burnt to obtain energy for the delignification process which creates it, as its non-uniform monomers make it difficult to work with in controlled chemical environments. 

Building on research from the past 30 years, this SUPER project aims to create a lignin-based raw material to be used in polymer-based chemical solutions, thus replacing much of the fossil-based raw material involved in creating adhesives. 

Lignin as a binder material in dispersions 

While the “Functionalised lignin” project focuses on altering lignin so that it can serve as a raw material for existing adhesive production methods and formulas, the “Lignin as a binder material in dispersions” project approaches the problem from the other end.

This means altering existing formulas and processes by introducing compounds and additional materials that make it possible for lignin to be used as it is received from the raw material manufacturers. 


Productive Projects – Digital & sustainable construction process

Digital traceability – Digital Product Passports (DPPs)

True sustainability depends on all actors within the value chain being transparent and honest about their products and production methods. This openness allows for easier options when it comes to, for example, reuse, repair, as well as maintenance. However, this information may be difficult to come by on its own, and may require external expertise in the case of specialised products or equipments.

As part of broader European initiatives and trends to encourage transparency in production through digital solutions, Digital Product Passports (DPPs) will contain the necessary information about the product, its producers, and other useful information such as where replacement parts can be sourced from, or how to maintain it for it to have the longest possible useful lifetime. Additionally, it will incorporate data from environmental product declarations (EPDs) about how sustainable the product is, in terms of life-cycle emissions, thus allowing consumers and businesses to make more sustainable choices, and giving the producers an objective metric according to which their products may obtain a competitive advantage.

Reusable Projects – Enabling construction circularity

Debonding on demand (DoD) – Adhesive technology for building materials and systems

Construction processes require the bonding of different elements together, such as building elements, as well as interior elements like tiles and laminates. The use of traditional bonding agents does not allow for the different components to be separated without risking damage, which leads to low repairability and modularity, increasing the frequency of total replacements and thus resource consumption. This course of action has proven to be detrimental to our environment, and unsustainable in the long term.

The technology behind DoD was conceived as a solution to this problem, enabling the reuse of building materials and components. The heat-induced debonding creates a new avenue for innovation and enables new business models and opportunities, speeding up the transition to a circular economy.
