“…SS was obtained from the wastewater treatment plant (WWTP) of Navàs, Barcelona, which treats 1500 m 3 •d −1 of domestic wastewater. Diatomaceous earth (DE) was obtained from the organic fraction of municipal solid wastes (OFMSW) biomethanization plant of Can Barba in Terrassa, Barcelona, and pruning waste (PW), used as bulking agent, was obtained from the composting plant of Manresa, Barcelona.…”

“…Nowadays, different treatment processes are used to handle and manage all SS produced, such as land application, incineration, composting, or anaerobic digestion, aiming at reducing its volume and quantity as well as stabilizing it [2]. In fact, one of the most typical and applied stabilization approach, composting, is considered an environmentally friendly technology that reduces sludge volume and transport costs, decomposing organic matter into a stable end product and removing malodorous compounds as well as pathogens and weeds [3].…”

Many different alternatives exist to manage and treat sewage sludge, all with the common drawback of causing environmental and odour impacts. The main objective of this work is to present a full inventory of the gaseous and odorous emissions generated during the bench-scale composting of conventional sewage sludge, aiming at assessing the process performance and providing global valuable information of the different gaseous emission patterns and emission factors found for greenhouse gases (GHG) and odorant pollutants during the conventional sewage sludge composting process. The main process parameters evaluated were the temperature of the material, specific airflow, average oxygen uptake rate (OUR), and final dynamic respiration index (DRI), resulting in a proper performance of the sewage sludge composting process and obtaining the expected final product. The obtained material was properly stabilized, presenting a final DRI of 1.2 ± 0.2 g O2·h−1·kg−1 Volatile Solids (VS). GHGs emission factor, in terms of kg CO2eq·Mg−1 dry matter of sewage sludge (DM–SS), was found to be 2.30 × 102. On the other hand, the sewage sludge composting odour emission factor (OEF) was 2.68 × 107ou·Mg−1 DM–SS. Finally, the most abundant volatile organic compounds (VOC) species found in the composting gaseous emissions were terpenes, sulphur compounds, ketones, and aromatic hydrocarbons, whereas the major odour contributors identified were dimethyldisulphide, eucalyptol, and α-pinene.

“…In recent years, legislation that limits the disposal of waste to landfill (e.g., The Landfill Directive in the EU; European Commission, 2001) has positively affected the circular bioeconomy by forcing the integration of agriculture with the water treatment (Grace et al, 2016) and wastewater treatment sectors (Colón et al, 2017). For example, drinking water treatment residuals from water treatment plants, rich in aluminum or iron and which is currently primarily sent to landfill, may be reused as an adsorbent medium to reduce P in runoff, or as an amendment to reduce GHG from stored slurry.…”

Future Phosphorus: Advancing New 2D Phosphorus Allotropes and Growing a Sustainable Bioeconomy

et al. 2019

With more than 40 countries currently proposing to boost their national bioeconomies, there is no better time for a clarion call for a “new” bioeconomy, which, at its core, tackles the current disparities and inequalities in phosphorus (P) availability. Existing biofuel production systems have widened P inequalities and contributed to a linear P economy, impairing water quality and accelerating dependence on P fertilizers manufactured from finite nonrenewable phosphate rock reserves. Here, we explore how the emerging bioeconomy in novel, value‐added, bio‐based products offers opportunities to rethink our stewardship of P. Development of integrated value chains of new bio‐based products offers opportunities for codevelopment of “P refineries” to recover P fertilizer products from organic wastes. Advances in material sciences are exploiting unique semiconductor and opto‐electrical properties of new “two‐dimensional” (2D) P allotropes (2D black phosphorus and blue phosphorus). These novel P materials offer the tantalizing prospect of step‐change innovations in renewable energy production and storage, in biomedical applications, and in biomimetic processes, including artificial photosynthesis. They also offer a possible antidote to the P paradox that our agricultural production systems have engineered us into, as well as the potential to expand the future role of P in securing sustainability across both agroecological and technological domains of the bioeconomy. However, a myriad of social, technological, and commercialization hurdles remains to be crossed before such an advanced circular P bioeconomy can be realized. The emerging bioeconomy is just one piece of a much larger puzzle of how to achieve more sustainable and circular horizons in our future use of P. Core Ideas Society's vision for a more circular economy must go beyond the C cycle to include P. Some biofuel systems have widened P inequalities and contributed to a linear P economy. New bioeconomy in bio‐based products offers an opportunity to rethink P stewardship. A circular bioeconomy requires efficient P reuse, recovery, and recycling from waste. New 2D P allotrope technologies offer a potential antidote to our current P “paradox.”

“…2 Biosolids, mostly based on the urban wastewater sewage sludge, were applied as fertilizer providing abundant plant nutrients and organic matter to soils and will improve and stimulate plant growth. 3 It was considered an important biological resource for sustainable agriculture, which is economical and bene cial. The only disadvantage of the application of biosolids in agriculture is their pollutant load, the contaminants of emerging concern (CECs), including heavy metals, organic compounds, pharmaceuticals, and nanoparticles.…”

This work presents the most extensive proteomic description of Arabidopsis thaliana in the knowledge of its responses to BPA and TiO2-NPs. Previous studies have reported that nanoparticles (NPs) and Bisphenol A (BPA) are toxic to the environment. However, the jointed toxicity is not yet well understood. This study was aimed to investigate the combined toxicity of BPA and TiO2-NPs to plants. Model plant Arabidopsis thaliana was selected as the target plant. The seedlings were randomly separated into 5 groups and treated with BPA (1000, 100, 10 and 0 µg/kg) and TiO2-NPs (100, 10, 1 and 0 mg/kg). The plant height, biomass and root length indicated no significant toxicity of low concentration of BPA and TiO2-NPs to the growth. In the results of comparative proteomics, both positive and negative effects were observed in root growth, plant development and energy metabolism, et.al, according to GO and KEGG analysis.
