Every year huge amounts of bottom sediments are extracted worldwide, which need to be dis-posed. The recycling of bottom sediments for soil fertilization is in line with the long-promoted circular economy policy and enables the use of micro and macronutrients accumulated in sedi-ments for soil fertilization. When considering potential agricultural reuse of the dredge sediments, the first necessary step should be to analyze whether...

Six treatments including straw biochar and its blends with organic waste (a mixture of anaerobically digested model kitchen waste, stillage and its enhancement with the fish waste digestate, both solid and liquid fractions) were tested via greenhouse experiment using fast-growing and pollution-resilient Miscanthus × giganteus. The four months long tests under spring/summer conditions in northern Poland with six fertiliser loads...

Exponential increases in energy consumption and wastewater have often irreversible environmental impacts. As a result, bio-electrochemical devices like microbial fuel cells (MFCs), which convert chemical energy in organic matter to electricity using exoelectrogenic bacteria, have gained interest. However, operational factors affecting efficiency and energy output need further study. This research investigated bioenergy production...
