We rely on quality
Our certification according to DIN EN ISO 9001 is a matter of course. Each of our products is subject to a severe quality control. We are able to use any data of chemical analysis of each recipe independent from the date of production. Each container is labeled with a batch number and the shelf life which guarantees complete traceability.
Our environmental policy
Being a company of the chemical industry we are aware of our activities and their environmental impact. This is the reason why WIGOL® W. Stache GmbH aims to use environmentally friendly products and methods in the production as well as in the application. Due to the ongoing improvement of methods used by our customers environmentally friendly products are enforced and possible savings are realized.
WIGOL® and its employees adjust all their activities to an appropriate environmental protection, responsible actions and compliance with all legal regulations.
Proper use
The important environmental impacts of our activities are given by the way how our customers are using our products. Therefore, we attach great importance to advising our customers regarding the proper use of our products because we feel responsible for the environment. Our application advisors support our customers regarding the optimization of their cleaning methods. Important steps here are to determine the optimum, usable concentration, to optimize bath cleaning equipment in order to extend the service life of baths, the appropriate waste water disposal concept and the continuous monitoring of dosing units.
Environmental-friendly products
WIGOL® produces cleaning and disinfecting agents for a large variety of application of various business areas. Whether in the food and beverage industry, the surface technology or in the general industry, environmentally friendly systems can be used everywhere.
These are our main efforts:
reducing the use of media with chlorine and thus reducing the AOX pollution
increasing the use of neutral cleaning agents
reducing pollutants such as phosphate, sulfate, EDTA and NTA
Raw material management
When selecting raw materials to be used the environmental compatibility regarding the transport, the usage and the wastewater contamination is specially taken into account.
When using dangerous substances in our products we are continuously aiming at reducing the risk potential by using raw materials which are classified less hazardous in accordance with legal demands.
Storage of materials which are hazardous to waters
Appropriate protection and safety precautions have been made for the handling and storing of dangerous substances. Dangerous raw materials, semi-finished and finished goods need to be stored in accordance with the regulations either in double-walled tank units or in pallet racks with appropriate drip trays. The unloading and loading areas also need to be provided with the appropriate safety measures which prevent from contaminating the earth.
The whole premises of WIGOL® are designed as an additional collecting pan and can be used as a fire water retaining basin.
Energy management
The most important energy consumer is the in-house heating system which is used to heat the manufacturing and administration rooms as well as to generate hot water. Electrical energy is required for the necessary pumps, agitators, lightning and the in-house waste water treatment plant. The truck fleet is essentially powered using diesel fuel.
Waste management
WIGOL® separates the waste and dispose of it according to its capability of being reused. Besides the waste generated during the production we also dispose of the cans returned by our customers. Every customer has the opportunity to return used cans with our vehicles free of charge. All used containers are cleaned and refilled according to their size, or shredded and delivered to the plastics recycling.
Waste water management
The transportation of waste water is the decisive factor in the whole waste management of WIGOL®. The whole water consumption is covered by the drinking water network of Worms. The whole waste water passes a two-stage waste water treatment plant, and a partial stream is used as water for the industrial use for low-ordered cleaning processes after the first treatment step.
In the second treatment step the waste water which is no longer intended to be reused is guided through an activated carbon filter and fed into the municipal sewage system.
