Search for Successfully Implemented Alternatives

You can use the free text search function to find information in the case story database. Most suitable are: substance name and other substance identifier (EC- and CAS-number). You can refine your search after first entry for sector-, function- and process-categories. The case studies are meant to serve as source of inspiration and ideas for substitution. The alternatives are constantly being developed further. We therefore recommend that you to check in each individual case whether an alternative is suitable for your applications and purposes. If you are aware of any other relevant information that is not mentioned in the current case story, please contact SUBSPORTplus.

Environmentally friendly PVC-Stabilisation using synthetic hydrotalcites

Polyvinyl chloride (PVC) is one of the most important commercial plastic materials, but it is thermally unstable at a processing temperature. Processing of PVC at elevated temperatures requires the use of thermal stabilisers. Widely used thermal stabilisers for PVC incorporate toxic heavy metals like lead or cadmium and another organotin compounds that have been severely criticised based for human health and environmental concerns. In order to address this issue, hydrotalcites that are compatible with the polymer had been investigated.

The cleaning of old frescoes with a bacterial suspension

This case story presents the use of Pseudomonas stutzeri for the biocleaning of mural paintings, for the purpose of eliminating remains of organic material from old restorations or insoluble saline efflorescence. Traditional techniques used in cleaning involve: solvents, spirits, alkalis, acids and soaps, as well as simple mechanical actions (ex. scraping with a scalpel).

Vegetable oils can be used as sustainable insulating and cooling liquids in transformers

It was estimated that globally each year about 5.7 million tons of fresh transformer oil is needed. Substitution of mineral oil by vegetable oil would be an important contribution to sustainable development.

Clay plasters for ecological building services

The advantages of clay plasters such as versatility, flexibility, ease of application and cost-effectiveness make them a practical alternative to gypsum based plasters. Further, clay plaster has excellent properties, regulating both temperature and humidity, making it ideal for breathable constructions.

Eliminierung der Phthalate DEHP, BBP, DBP und DIBP aus Elektronikprodukten auf eigene Initiative

DEHP, BBP und DBP sind Phthalate mit geringer molarer Masse, die verwendet werden, um Kabel weicher und flexibler zu machen. Diese Phthalate sind in die REACH Kandidatenliste aufgenommen worden und wurden in Zusammenhang mit der RoHS-Neufassung diskutiert. Gemäß dem Vorsorgeprinzip hat Dell beschlossen, auf eigene Initiative die Phthalate aus allen Produkten zu entfernen. Die Phthalate wurden durch Tris(2-ethylhexyl)benzol-1,2,4-tricarboxylate (TOM oder TOTM) oder Bis(2-ethylhexyl)terephthalat (DOCP) ersetzt. TOM und DOCP bieten dieselbe Funktionalität, sind aber weder eingestuft noch sind sie CMR Stoffe. Dell hat außerdem begonnen, von seine Zulieferer zu verlangen, die Verwendung zusätzlicher Phthalate(DIDP, DNOP, DIBP, DHNUP, DIHP) offenlegen, um einen stufenweisen Ausstieg aus deren Verwendung zu ermöglichen.

Proactively eliminating the phthalates DEHP, BBP, DBP and DIBP from electronic products

DEHP, BBP, and DBP are low molecular weight phthalates used to make cables softer and more flexible. These phthalates have been included in the REACH Candidate List and have been discussed in context of the RoHS recast. In line with the its precautionary principle, Dell has decided to proactively eliminate these phthalates from all of its products. The phthalates have been replaced with Trioctyl Trimellitate (TOM or TOTM) or Dioctyl Terephthalate (DOCP). TOM and DOCP offer the same functionality, however these are neither classified nor labelled and are not CMR substances. Dell has also started to request that its suppliers disclose the use of additional phthalates (DIDP, DNOP, DIBP, DHNUP, DIHP) to enable swift phase out of these as well.

Substitution of a floor cleaning product in a company

A cleaning services cooperative decided to try to substitute all its products containing hazardous chemicals by safer products. Substitution started with a cleaner containing trisodium nitrilotriacetate, a category 3 carcinogenic harmful and irritant chemical (R22, R36, R40). The new products were chosen taking into account health and environmental criteria.

Substitution of chemical products used for radiography fixation and developing with a digital system

The radiology service of the hospital Parc Taulí, Spain, used several chemical products for fixing and developing X-rays. These products, widely used in hospitals, contain hydroquinone, which is carcinogenic and a neurotoxic and boric acid which is an endocrine disrupter. In 2004 these products were replaced by a digitised radiography system. This is a display of digital medical imaging for diagnostic use with a range of software called RAIM.

Substitution of a degreaser in a cleaning company

A cleaning services cooperative decided to try to substitute all its products containing hazardous chemicals by safer products Company managers substituted a degreaser containing butoxyethanol, a hazardous chemical that is neurotoxic and endocrine disruptor. The alternative product was chosen according to health criteria (toxicity) but certain environmental principles during its manufacture were also taken into account.

Substitution of a hydrocarbon-based anti-adherent used in industrial welding

A highly flammable anti-adherent compound containing toxic solvents used in welding was substituted by a water-based product. The eliminated product contained dichloromethane which posed serious health hazards since it is a suspected carcinogen and endocrine disruptor. The alternative product contains synthetic oils and water-based anti-corrosion additives.
