Wood and cork waste

Fichier Wood and cork waste

General informations

Coating of wood as paint and lacquer as well as wood preservers contain toxic substances, which may not get into the environment. The same applies to plywood and chipboard, which contain glue, bonding agents and resins. Wood dust and in particular dust from beech and oak wood can be cancerous. Use a performing aspiration and protective clothing when working with these wood types.

Prevention / reduction

Use returnable palettes and ask specialist companies to repair damaged palettes, this saves money and raw material. Cork is a good isolation material, which may also be used as flooring material.

Recycling / environment correct disposal

Untreated wood can be used as raw material in the production of chipboard. Treated wood has to undergo heat treatment in special installations. Cork waste is shredded and used for the production of insulation material and additives.

Safely Dispose of Used Railroad Ties

Used railroad ties are usually treated with creosote, a tar oil. This biocide is classified as a carcinogen. It is absorbed through the skin and contaminates groundwater. In addition to the impregnating agents, other problematic residues such as oil, rust or herbicides may be found in the wood.

The SuperDrecksKescht® fir Bierger collects the ties from the consumer free of charge upon request. Only wooden ties are collected. They must be disassembled and properly stacked for forklift removal. (For example, ties may be stacked on a palette or a square timber.)

Caution :

  • Wear appropriate gloves when handling ties. In case of old, brittle ties, we also recommend wearing a dust mask.
  • Never use railroad ties as firewood.

The wooden ties are processed from the SuperDrecksKëscht® via the partner Oekolux to the special company BHKW Flohr in Germany (Neuwied). There they are – after a pre-treatment – utilised in a thermal power plant for biomass. This process generates electricity and district heating.

Railway ties contain components that are hazardous to the environment and health ! We take care of it !

The correct handling of wood ash

Decisive for the disposal of wood ash is the type and origin of the fuel and the quantity.

In the private environment, ash is produced, for example, by burning logs in fireplaces and stoves as well as by pellet heating systems.

Wood ash is not a typical problem product that can be handled via the SuperDrecksKëscht®. Also, the resources centers do not accept ash.

The correct way is usually to dispose of the cooled ash via the domestic waste. Of course, hot ash should never be placed in the plastic waste containers used today.

There is no objection to the use of ash as a home remedy, for example for cleaning the glass panes of stoves, provided it is then disposed of as indicated. This way you can avoid additional chemical cleaning agents. Requirements: the fuel is natural and untreated fuel from sources that can be trusted, such as hardwoods (beech, oak, ash, fruit trees).

It is not advisable to use ash as fertiliser in the garden or to put it on the compost heap. Why should caution be exercised here?

Wood ash may be contaminated with heavy metals, which trees and shrubs absorb and concentrate. The content of heavy metals, especially lead, cadmium and chromium, is difficult to estimate. Since wood ash is alkaline, in too high a concentration it can also destroy the microorganisms working in the soil and compost. Summary: the exact proportions of the minerals is not known, nor can the concentration of heavy metals in the wood ash be estimated without an analysis. Thus, fertilisation adapted to the pH value of the soil is not possible and there is a risk of enriching the soil in the garden with toxic substances.

For all these reasons, disposal is virtually a question of quantity. In the case of larger pellet heating systems, such as in residences, the quantity alone indicates that disposal via residual waste no longer makes sense. This is where authorised disposal companies come into play, which also offer the professional disposal of wood ash in Luxembourg. Local and district heating systems (e.g. Luxenergie) or Kiowatt in Roost also make use of these disposal companies.

Recycling of larger quantities

The wood ash existing here in large quantities is analysed and further treated according to the quality. This can be:

  • – landfilling
  • – production of a standardised fertiliser after pre-treatment
  • – aggregates in the cement industry
  • – aggregates in road and path construction
  • – backfill material in mining

This was the subject of a study from March 2020 – Possibilities to utilise ash from the calorific usage of fuel from natural wood with special consideration of a usage as fertiliser and soil improver, commissioned by the Luxembourg Environmental Administration.
