Frequently asked questions

What distinguishes bio-based release agents from hydrocarbon-based ones?

Bio-based release agents such as our Antistick ECO range consist mainly of rapeseed oil derivatives. They are biodegradable, have high flash points (typically over 150 °C), do not produce any relevant VOC emissions and usually do not require hazardous substance labelling. A detailed comparison can be found in our article Asphalt release agent: rapeseed oil vs. hydrocarbon.

Does Green4Clean also deliver outside Germany and the Netherlands?

Yes, Green4Clean delivers throughout Europe. Standard sizes such as 200-litre drums and 1,000-litre IBCs are usually available at short notice.

Does Green4Clean offer free test samples?

On request, we can provide existing customers and qualified interested parties with test samples of 10 or 20 litres. Please contact us via the contact form or by telephone.

Are the products suitable for food or drinking water areas?

Our products are primarily developed for industrial and road construction applications. For sensitive areas such as drinking water zones or in the vicinity of foodstuffs, we check their use on a case-by-case basis with our application engineers.

Industries

Green4Clean solutions are designed for real-life operating conditions: changing weather conditions, heavy soiling, sensitive surfaces, strict safety requirements and high operating cycles.

Typical fields of application:

Municipal enterprises & public institutions (building yards, workshops, vehicle fleets)
Road construction and civil engineering (machines, tools, asphalt/bitumen-related areas)
Offshore and maritime applications (corrosion protection, maintenance, technical cleaning)

Road construction

Bio-based asphalt release agents, water-based bitumen cleaners and biodegradable oil binding agents for asphalt, road and civil engineering. Based on rapeseed oil instead of mineral oil - with full performance, but without hazardous substance labelling, without ADR hazardous goods and without VOC contamination.

Offshore

Cleaning and binding agent for platforms, ships, harbour and shipyard applications. Biodegradable, gentle on materials, safe in storage and transport - designed for maritime operating conditions and strict environmental regulations.

Products

Removes stubborn dirt such as oil, grease, soot, deposits and industrial residues
Water-dilutable cleaners for efficient applications with reduced solvent content
Solutions for removing adhesives, coatings and residues
Products for Decalcification and removal of deposits in systems, pipes and machines
Focus on user safety, material protection and process stability

The result: reliable cleaning with reduced risk - often combined with cost benefits thanks to faster processes, lower consumption and less safety expenditure.

Release agent

Release agent based on rapeseed oil for rollers, screeds, skips and tools in asphalt construction. Full release effect against hot mixes - without hazardous substance symbols, without ADR hazardous goods, without solvent odour.

Cleaning agents

Water-based cleaners with plant-based active ingredients for machines, tools and traffic areas. Dissolves bitumen, tar, asphalt, oil and grease - without solvent odour, without hazardous substance symbols, without damaging paintwork.

Liquid oil binding agents

Liquid, biosurfactant-based oil binding agents based on 100 % natural active ingredients. Removes traces of oil from traffic areas, harbour areas and workshop access roads - and then supports the biodegradation of the bound pollutants.

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.

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.

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.

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.
