“…Lignin is difficult to degrade and is chemically bonded with hemicellulose. In addition, this complex enwraps cellulose, slowing down these carbohydrates degradation (Huang et al 2010). Despite the fact that TH half-life is similar for all treatments, degradation rate was also relatively higher in 75 % OW than in 0 and 33 % OW.…”

Oil-based drilling cuttings comprise a large and hazardous waste stream generated by oil and gas wells drilling operations. Oil-based cuttings are muddy materials with high contents of salts and hydrocarbons. Composting strategies have shown to be effective in the biodegradation of petroleum hydrocarbons, and it offers numerous advantages in comparison with other bioremediation methods. In order to assess the effectiveness of drilling cuttings bioremediation by composting with food and garden wastes, an experiment was conducted in 60-L reactors for 151 days. Four treatments were carried out: only oil-based cuttings, two proportions (in a volume basis) of organic wastes to drilling cuttings (33 and 75 %) and only organic wastes (as a traditional composting reference), with pine-tree woodchips as bulking agent. High degradation percentages of total hydrocarbons (&82 %), n-alkanes (&96 %) and the 16 USEPA-listed polycyclic aromatic hydrocarbons (&93 %) were reached in the treatment with 75 % of organic wastes, and applying 33 % of organic wastes was not more effective than not applying organic wastes for the drilling cuttings hydrocarbons biodegradation. Furthermore, in the treatment with 75 % of organic wastes, alkanes half-life and polycyclic aromatic hydrocarbons half-life were about 10 times and four times lower, respectively, than those in the treatment with 33 % of organic wastes. Possibly, lower hydrocarbons and salts initial concentrations (i.e., lower toxicity), higher microbial counts, adequate nutrient proportions and water content supported a high biological activity with a consequent elevated biodegradation rate in the treatment with 75 % of organic wastes.

“…This can be accounted for by a high (initial) content of extractives in the composites and/or by a high cellulolytic activity of A. niger [19,47]. Huang et al [48] indicated in 2010 that the lignin-carbohydrate complex constitutes a barrier for accessibility to cellulose and hemicellulose, thus lowering the rate of biodegradation. However, due to the content of particular plant fillers (low amount of lignin) and their origin (coniferous), the observed effect might probably be associated with the share of extractives.…”

“…It was accompanied by the occurrence of the peak spectrum characteristic for cellulose (1317 cm −1 ). Biodegradation of lignocellulose (derived from the plant filler) of the composites results from collaboration of some fungi, actinomycetes and bacteria [48,[71][72][73]. The observed differences can be indicative for different proportions of cellulolytic and ligninolytic microorganisms which have the ability of decomposing resin acids in both substrates.…”

Purpose Lignocellulosic biomass waste is produced in large quantities and only a small part is used for utility purposes. The aim of the work was to assess the fertilization value of the solid fraction and water extract of lignocellulosic composts. Methods Compost I contained 42.86% pine bark, 34.28% grass, 20.0% sawdust and 2.86% chicken feathers; compost II contained 25.54% pine bark, 10.63% wheat straw, 51.07% sawdust and 12.76% chicken feathers. Seldom described physical properties and phytosanitary and sanitary status of composts as well as macro-and micronutrients and heavy metals concentrations were determined in the solid fraction and water extracts of composts and their impact on the germination of Lepidium sativum L. using PC analysis. Results Composts were characterized by good physical properties and a light product, safe phytosanitary status, which was related to the prevalence of potentially antagonistic fungi, especially in compost II. The frequency of Aspergillus fumigatus, considered an opportunistic human pathogen, decreased during the composting. Heavy metal concentrations did not exceed permissible values for improvers and cultivation media in the solid and aqueous compost fractions. The tested composts were sanitary safe. Both composts were non-toxic to plants, because the germination index in compost I was PCA analysis demonstrated that the majority of micro-and macronutrients and heavy metals had a significantly negative effect on root elongation and germination of the test plant (cress) seeds, especially in compost I. Conclusions Lignocellulosic waste after composting is a valuable and safe organic fertilizer.
