Bio-based cleaning chemicals in asphalt construction - benefits, limits, cost-effectiveness

„Bio-based“ and „sustainable“ are no longer just marketing phrases in industrial cleaning. Behind the terms are concrete technical concepts, clear regulatory drivers - and considerable practical consequences for users. Anyone buying asphalt construction, offshore or construction yard products today is not only faced with a growing range of bio-based products, but also the question: Do these products deliver what they promise? Is substitution economically viable? And what limits need to be honestly recognised? This article summarises what is behind bio-based cleaning chemicals, where they stand technically today, where the limits are and what a serious economic assessment looks like. We deliberately avoid making overly promotional promises - we want you to be able to make an informed decision.

Asphalt release agent: rapeseed oil or hydrocarbon - which is right for your business?

Sooner or later, every asphalt paving company faces the question of whether the release agent used is still up to date. For many years, hydrocarbon-based products were the standard - simple, cheap and efficient. In the meantime, three factors are pushing in a different direction: stricter substance legislation (CLP, REACH, ADR), increasing requirements for occupational safety and sustainability - and the fact that bio-based alternatives have caught up technically. This article compares both families of release agents from a technical and operational point of view: their chemical basis, their effect, their risks and their practical consequences for spraying systems, warehouses and personnel. At the end, you will find a decision-making aid to help you decide which variant is best for which application - and which of our products are suitable.

Bitumen cleaning - correct maintenance of machines, rollers and tools in asphalt construction

Bitumen is sticky. It is precisely what it does in the mix that makes it a nuisance in the construction yard: bitumen residues stick to roller drums, tyres, screeds, troughs, tools and painted surfaces. If this coating is not removed regularly and with the right agent, subsequent problems accumulate: release agent adheres less well, drums become misaligned, tools become unwieldy, painted surfaces become dull and lose their protective function in the long term. This article shows how bitumen cleaning works in modern construction yard operations: which cleaner classes are available, why water-based bitumen cleaners can now replace most classic solvent products, and how you can establish a pragmatic cleaning routine that extends machine service life and reduces the workload on personnel.

Sustainability & bio-based chemistry

What „biobased“ means in technical terms, what it means in regulatory terms (CLP, REACH, ADR, Green Public Procurement) and where the honest limits lie. With a total cost of ownership calculation instead of marketing platitudes.

Offshore cleaning - understanding salt corrosion and countering it with the right products

Offshore cleaning is not simply „cleaning in a damp environment“. It is the answer to a permanent attack: salt water, salt aerosols, biological deposits, traces of fuel and oil, mechanical wear caused by wind and waves. Anyone who maintains platforms, ships, cranes or harbour facilities is fighting against corrosion at a speed that an industrial site on land can never match. At the same time, the regulatory scope is tight: anything that is brought on board or into maritime waters is subject to strict regulations - national, EU-wide, OSPAR, MARPOL. Cleaning that solves the corrosion problem but exacerbates the environmental problem is not a solution. This article shows how modern offshore cleaning solves the tension between effectiveness and environmental compatibility, which product types are used today, and how you can protect both steel and the environment with the right routine.
