Waste disposal such as sewage sludge (biosolids) in phytoremediation is a sustainable remediation alternative for fertilizers, therefore there is a need to develop a test that will allow to determine phytoremediation dose of biosolids from the best-for-plant-growth point of view. In order to determine the doses of biosolids to degraded soils, tests based on germination of seeds and root elongation are commonly used, but also, they are subjected to large errors caused by low repeatability of results and differentiation. That is why there is a need to introduce new testing solutions that will be of use based on more reliable indicators such as biochemical activity of selected plant enzymes. The aim of the study was to demonstrate high efficiency of the guaiacol peroxidase activity (GPX) in plant-based toxicity tests used as an optimal dose amendments indicator in heavy metal degraded soil phytoremediation process. GPX were measured in underground and above ground parts of Sinapis alba L. and Brassica rapa L. instrated that the optimal phytoremediation dose of sewage sludge was in the range of 15-20%, with values of 5% and 25% respectively favoring or inhibiting plant development expressed in GPX activity. The most differentiating GPX values were obtained for the roots.Measurement of GPX activity in the roots of Sinapis alba L. cultivated on soil agar-based tests is a good, new and easy additional or alternative to the old tests based on germination and increase biomass measuring as an indicator in the assessment of optimal phytoremediation sewage sludge. Oxy-combustion is one of the most promising technologies for carbon capture and sequestration. When CO2-neutral biomass is burned under oxy-combustion conditions, named "oxy-biomass combustion" a negative CO2 emission can be achieved. However, the high content of potassium and chlorine in biom
