Tests for doc-leaching from waste materials (NT TR 582)

NT TR 582

  • Decision 2003/33/EC establishes procedures and criteria for different parameters needed in the acceptance of waste at landfills in accordance with the EU Landfill Directive. One of these parameters is dissolved organic carbon (DOC). This parameter is a consequence of the need for gradually reducing the landfilling of biodegradable waste in order to reduce green house emissions.

Leaching tests for non-volatile organic compounds - development and testing (NT TR 576)

NT TR 576

  • The main objective of this project was to develop a leaching test method suitable for organic non-volatile compounds. The project was performed in two parts.

CEN EN 12457 leaching test - Comparison of test results obtained by part 1 and 2 with test results obtained by part 3 (NT TR 539)

NT TR 539

  • The report compares leaching results obtained by two one-step batch leaching tests (en 12457 part 1 and 2) with leaching results obtained by a two-steps batch-leaching test (EN 12457 part 3). The effect of the used contact time and the effect of using different number of leaching steps were evaluated.

Acceptance criteria for landfilling of waste under nordic conditions (NT TR 520)

NT TR 520

  • In the report the various classes and sub-categories of landfills that are possible within the framework of the EU Landfill Directive are presented and discussed, and the need within the Nordic countries for sub-categories of the three main classes of landfills (inert, non-hazardous and hazardous waste landfills) is evaluated.

Undersøgelse af mulighederne for automatisering af kolonnetesten NT ENVIR 002 (NT TR 519a)

NT TR 519a

  • The column test NT ENVIR 002 is used to obtain information on the leaching behaviour and characteristics of solid materials especially at low liquid/solid (L/S) ratio. The column test can therefor be used to evaluate the leachability of different compounds under landfill-like conditions.

Tillverkning och användning av laboratoriereferensmaterial vid testing av fast avfall (NT TR 486)

NT TR 486

  • Costly certified and commercial reference materials can often not be applied for waste testing because of high test portion quantities needed and poor availability of suitable commercial soil and waste materials. The utilisation of a laboratory reference material can be regarded as a practical tool in the quality control of leaching test performance.

Use of lysimeters for characterisation of leaching from soil and mainly inorganic waste materials (NT TR 473)

NT TR 473

  • The understanding and interpretation of leaching processes have improved significantly during the past two decades and several Nordic countries have implemented the use of leaching tests in recent or pending legislation on utilisation and landfilling of waste and contaminated soil. This progress is based mainly on experience from laboratory experiments in combination with modelling work but also on the use of field lysimeters.

Influence of critical test conditions on the results of pH-dependent leaching tests (NT TR 466)

NT TR 466

  • The purpose of the project has been to investigate the influence of some potentially critical test conditions on the results of pH-dependent tests. Two types of pH-dependent tests, the pH static test and the ANC-test were considered.

Development of tests for characterising the leaching of organic compounds from contaminated soils and waste products (NT TR 464)

NT TR 464

  • The main purpose of this project has been to evaluate primarily the technical feasibility of applying and standardising leaching tests that may be used to describe the leaching of organic components from contaminated soil and waste materials.
