State working group on waste

from Wikipedia, the free encyclopedia

The Federal / State Working Group on Waste (LAGA) is a working body of the German Conference of Environment Ministers .

LAGA was founded on July 2nd, 1963 . Its objective is to ensure that waste law is implemented as uniformly as possible across the country in the Federal Republic of Germany. It publishes recommendations for this in the LAGA - Mitteilungen (LAGA M).

The LAGA and its resolutions are important in environmental issues, especially in the case of construction and renovation measures and certain operational waste. Many have now been declared invalid or overtaken by the rapid changes in legal material and knowledge in waste law. Some of their valid publications can be understood as the formulation of technical rules .

LAGA M 20

In its most important communication 20 from 1997, updated in 2003 and 2004, it formulated "Requirements for the recycling of mineral residues / waste", i.e. technical rules for excavated soil or broken bricks or concrete from demolished buildings (rubble) and their recycling, e.g. B. by installation in soils elsewhere.
It has defined various categories, depending on maximum pollutant values, for exploration and treatment and recovery based on this, if necessary, removal of excavated soil and other mineral waste, especially as recycled building material, for example for level control of properties, as a base course for roads, etc. For other types of waste such as slag / ash, for which regulations were originally announced in the special section, nothing has been communicated (as of 2019). It is not applied consistently by the environmental authorities, particularly with regard to the classification and use of construction waste in the federal states.

In order to determine which category the material belongs to, it must be sampled, e.g. B. by a pile analysis . The chemical composition of the material is clarified by analyzing the sample obtained. Specific ingredients such as various metals, PCBs , PAHs and other substances in the solid and in the eluate are searched for. The analysis results obtained are compared with the assignment values ​​listed in LAGA M 20. Depending on the pollutant load, the material is classified in one of the LAGA installation classes, which regulate the possibility of further use of the material.

There are the following allocation values ​​(upper limits of the installation class): Z0, Z1, Z2, Z3, Z4 and Z5, where Z0 is the group with the lowest load and therefore the freest, broadest usability.

Recycling takes place in installation class 0 (unrestricted installation), installation class 1 (limited open installation) and installation class 2 (limited installation with defined technical safety measures).

- Unrestricted installation

- Restricted open installation, subdivided again into Z1.1 and Z1.2 - up to the allocation value Z1

- Restricted installation with defined technical security measures - up to the allocation value Z2

A landfill in landfills takes place in accordance with landfill class I (AbfAblV / Landfill Ordinance (DepV)), landfill class II (AbfAblV / DepV) and landfill class III (DepV) - hazardous waste landfill.
