Abstract: A method and plant for waste disposal are provided. A recirculating arrangement recirculates leachates generated by the processes of waste treatment into the plant itself, namely into a biofilter. The leachates are treated without need for providing a dedicated arrangement for purification and disposal.

Preferably, the leachates are introduced into the biofilter at an intermediate height of the biofiltering material bed, so as to obtain a kind of “submerged irrigation” of the biofilter. More preferably, the leachates are introduced into the biofilter as homogeneously and dispersedly as possible, so as to obtain a kind of “micro-irrigation” system for the biofilter.

Abstract: Remediation materials are stored and treated within remediation cells constructed within a pond. The remediation materials originate from a variety of sources including the pond in which the remediation cells are constructed. The volume of the remediation cells is relatively small compared to the total volume of the pond and thus, the total active volume of the pond to handle stormwater flood events is not significantly diminished. Remediation of the remediation materials in the cells is accomplished through a variety of processes, including dewatering and/or by bioremediation therein. The water level in the remediation cells during normal operation outside flood events is maintained at levels which support the remediation processes. When the remediation cells are filled over time, remediated material can be removed for use in constructing other remediation cells, wetlands or marshes in the same or other ponds or can be located to areas remote from the pond.
