Definitions

  • the invention relates to a method for producing a peat substitute from vegetable raw materials and waste materials, in particular forestry and agriculture.
  • peat in the form of peat culture substrates or in other forms in gardening and plant cultivation is also known, as is its use for other purposes, such as e.g. as litter in animal husbandry or in medicine.
  • peat When used in gardening and planting, peat has gained a correspondingly high level of importance and popularity because of its many air pores, its large buffer capacity, its structural stability, its ability to hold water, its low volume weight and other positive properties.
  • Peat is a natural product that grows slowly, if at all. According to the definition, peat is referred to in the literature as an after-glacial organic formation formed from predominantly dead plant-based, in addition from animal organisms with the exclusion of air through water.
  • Peat still contains free cellulose. Up to 50% humic acids are present in the peat as the main component. When freshly obtained, peat contains up to 90% water, air-dry still 25 to 30%. For a long time now, attempts have been made to produce a peat substitute from vegetable raw materials and waste materials. A thermochemical process has become known by the University of Hohenheim, in which the rotting is traced. At temperatures between 150 and 200 ° C, the cellulose is split into fermentable sugar in a few minutes in the presence of acids, which is then extracted.
  • the undissolved residues obtained after mechanical defibration are called hydro-gauze and are said to have physical properties similar to peat, which is why they are used as a substitute for peat.
  • the invention has for its object to provide a generic method by which a peat substitute is obtained which has properties similar to peat and which is less energy-intensive.
  • the raw materials and waste materials are thermomechanically broken up and defibrated in a screw press and mixed together with mineral and organic additives.
  • the substances used are all of natural origin.
  • the raw and waste materials are renewable, wooded, vegetable residues from agriculture and forestry, as well as from the woodworking industry, preferably clean residual wood such as spruce or fir being used.
  • residual wood such as spruce or fir being used.
  • a mineral and organic additive to be mixed is a product sold by the company UWAS environmental service company for waste recycling and recycling mbH in D-8045 Ismaning under the brand "TORMIN" used mixed, which consists of natural raw and waste materials.
  • Moist vegetable raw materials and waste materials are introduced into the screw press, these being expediently comminuted.
  • the raw materials and waste materials are heated and disintegrated in the screw press by means of pressure and friction, the steam resulting from the pressing advantageously being used for steam decomposition of the raw materials and waste materials and the steam produced being removed together with the finished product.
  • the measured values of the peat substitute according to the invention were determined by the Bavarian Research Center for Agriculture in D-8050 Freising / Weihenstephan. It was found that the substitute has measured values that lie within the fluctuation range of natural peat.
  • the substitute has similar to identical properties to natural peat and - although it is made from waste and residues - is suitable for all the applications for which peat that was naturally created was used.

Abstract

Selon un procédé de production d'un succédané de tourbe à partir de matières premières et de déchets végétaux, notamment d'exploitations forestières et agricoles, les matières premières et les déchets sont thermomécaniquement désagrégés et dans une boudineuse à vis et mélangés avec des additifs minéraux et organiques. On obtient par ce procédé un succédané de tourbe dont les propriétés ressemblent davantage à celles de la tourbe que les succédanés de tourbe connus. Le procédé consomme moins d'énergie que les procédés connus de production de succédané de tourbe.
