The main waste generated during the thermochemical processes of biomass burning used
for bioenergy production in cogeneration plants are ash and biochar which can be used as …

Abstract Development trends need the necessity for wider use of the local resources and
available natural materials are one of the priorities around the world. Freshwater sapropel is …

Organic-rich freshwater sediments formed from the remains of water plants, plankton and
benthic organisms, which are transformed by microorganisms, and mixed with mineral …

Sapropel, a sediment rich in organic matter and bioactive compounds, has significant
potential for pharmaceutical and cosmetic applications. This study aimed to develop a …

Geochemical and lithological parameters of sapropel in lakes, combined with pollen data
and radiocarbon 14C dating, contain a wide spectrum of environmental information. This …

Clay materials were prepared with clay and sapropel (SP) or clay and modified (frozen)
sapropel (FSP) as the main raw materials. Clay-based materials were formed by mixing clay …

Found in lakes, freshwater sapropel is a sediment with a fine structure containing more than
10% of organic matter as well as residues of aquatic organisms with a small content of …

Background and Objective: Sapropel, a biologically active sedimentary deposit, is high in
organic matter and minerals and has been shown to offer health benefits. Its constituents …

An integrated approach to the processing of sapropel with the use of supercritical CO 2
extraction of bioactive substances with carbon dioxide at the first step of the process is …

The aim of this paper is to study possibilities to obtain composite materials using organic rich
lake sediments (further–sapropel) and lime as binders and hemp shives, wood fibre, and …
