Gentle remediation options (GRO) include various and in general plant-based Options to remediate trace element contaminated soils (TECS) at low cost and without significant negative effects for the environment. Although GRO comprise very innovative and effi cient technologies, they are still not widely used as practical site solution due to several hindrance reasons.
Contamination of soils with trace elements (TE) is a worldwide and thus also a pan-European problem. In EU countries, the number of potentially contaminated sites adds up to nearly 3 millions (EEA, 2007). Around 80,700 sites have been cleaned up over the last 30 years in the countries with available data on remediation. According to the European Environment Agency (EEA), at least 250,000 polluted sites in the member states require an urgent clean up. Current Investigation trends will increase by 50 % the number of sites needing remediation by 2025. Mineral oil(38 %), TE (37 %) and PAH (13 %) are the most frequent soil contaminants at investigated sites. Many industrial sites severely polluted with TE emitted from local sources have been identified inall European countries. Even wider areas are slightly or moderately contaminated with TE from diffuse sources such as traffic, waste management and application, mining and industrial activities.The low and moderate levels of pollution, which are clearly above European standards, have led to limitations in land use, especially to protect safety of plant-derived products and consumers. TE loading in the soil decreases the chances of the establishment and survival of non-metal tolerant plant species and may strongly decrease the biodiversity of local eco systems; the loss of biodiversity is also reflected in the animal community of these ecosystems.

Fremdstoffgehalte in den Sieblinien von Biogut nach Voraufbereitung
© Witzenhausen-Institut für Abfall, Umwelt und Energie GmbH (11/2024)
Fremd- und Kunststoffeinträge im getrennt erfassten Biogut rücken zunehmend in den Fokus des Gesetzgebers. Mit der Novellierung der BioAbfV treten zum 01.05.2025 erstmals Grenzwerte in Kraft, die sich auf das frische Biogut vor der biologischen Behandlung beziehen.

Like all public international law treaties, the Paris Climate Accords rely on national law for their implementation. The success of the agreement therefore depends, to a large extent, on the stepstaken or not taken by national governments and legislators as well as on the instruments and mechanisms chosen for this task. Against this background, the present article compares different approaches to the implementation of the Paris Agreement, using court decisions as a means to assess their (legal) effectiveness.
