“…In particular, the experience of Poland is cited as an example. In the absence of a political strategy to promote a circular bioeconomy, innovations are actively used, in particular, in the biogas industry [7].…”

“…In this regard, in the world theory and practice, new models of economic development focused on environmental welfare are becoming more widespread [3]. These include green economy, low-carbon economy, blue economy, green growth, bioeconomy, circular or circular, cyclical , restoration economy (circular economy) [4][5][6][7], and its variations, for example, circular bioeconomy [6,7]. Both at the macro level and at the level of individual enterprises, in long-term plans and reporting, an increasingly important position is given to adherence to sustainable development goals.…”

Development, leading to the depletion of resources, in modern conditions is not seen as long-term and sustainable. Accordingly, national strategies for security, long-term and territorial development of the countries of the world are being developed in accordance with the existing goals of sustainable development. This study examines the relationship of sustainable development with the goals of countries in the framework of the orientation towards the introduction of new models of economic development - a green and circular economy. The highly specialized applications of the noted models are considered, the ambiguity of the possibilities and results of their practical implementation is noted, depending on the level of development of states, the level of their incomes, social or economic priorities of their development. The advantages and disadvantages of the circular economy model are summarized.

“…The concept of circular economy (CE) consists of developing economic models that have minimal effects on the environment, ensuring a reduction in natural resource use and waste generation and promoting waste reuse as valuable co-products (Casson Moreno et al 2020 ). The development of a CE concept requires adopting closed-loop systems, facilitating the transformation from a linear economy to a CE to improve economic and environmental sustainability (Dessie et al 2020 ; Kaszycki et al 2020 ). This model can be especially important in Italy, where agriculture is one of the most productive sectors and, at the same time, responsible for generating large amounts of residues with different proprieties (Vahidzadeh et al 2021 ).…”

Within the circular economy framework, our study aims to assess the rhamnolipid production from winery and olive oil residues as low-cost carbon sources by nonpathogenic strains. After evaluating various agricultural residues from those two sectors, Burkholderia thailandensis E264 was found to use the raw soluble fraction of nonfermented (white) grape marcs (NF), as the sole carbon and energy source, and simultaneously, reducing the surface tension to around 35 mN/m. Interestingly, this strain showed a rhamnolipid production up to 1070 mg/L (13.37 mg/g of NF), with a higher purity, on those grape marcs, predominately Rha-Rha C14-C14, in MSM medium. On olive oil residues, the rhamnolipid yield of using olive mill pomace (OMP) at 2% (w/v) was around 300 mg/L (15 mg/g of OMP) with a similar CMC of 500 mg/L. To the best of our knowledge, our study indicated for the first time that a nonpathogenic bacterium is able to produce long-chain rhamnolipids in MSM medium supplemented with winery residues, as sole carbon and energy source. Key points • Winery and olive oil residues are used for producing long-chain rhamnolipids (RLs). • Both higher RL yields and purity were obtained on nonfermented grape marcs as substrates. • Long-chain RLs revealed stabilities over a wide range of pH, temperatures, and salinities

“…Consequently, utilities have to implement innovative solutions to deliver their services [ 1 , 2 , 3 , 4 ], and are setting ambitious goals: moving towards zero discharge to the air, water, and soil; creating value from waste; moving from cost coverage to profit; extracting the highest possible value from materials and resources; achieving no net-negative contribution regarding energy, greenhouse gas emissions and economy [ 5 , 6 , 7 , 8 , 9 ].…”

Concentration of Municipal MBBR Effluent by FO for Resource Recovery: Batch Experiments in Side-Stream Configuration

et al. 2021

A novel approach for resource recovery includes forward osmosis (FO) as a concentration step in municipal wastewater treatment. The current study investigates different pre-treatment strategies including biological treatment with a moving-bed bioreactor (MBBR) at different loading rates and particle removal by filtration and sedimentation. Membrane performance and recovery potential for energy and nutrients were investigated in laboratory-scale FO experiments in batch mode using pre-treated municipal wastewater as feed and 35 g/L NaCl as a draw solution. Initial water fluxes were in the range of 6.3 to 8.0 L/(m2·h). The baseline fluxes were modelled to account for flux decline due to concentration effects and to enable the prediction of flux decline due to membrane fouling. Fouling-related flux decline varied from 0 to 31%. Both organic fouling and precipitation of CaCO3 and CaHPO4 were identified by using SEM–EDS. High-rate flushing resulted in complete flux recovery under most conditions. Scaling could be avoided by lowering the pH. Two operation strategies were tested to achieve this: (1) applying a bioreactor with a low organic loading rate to achieve high nitrification, and (2) adding a strong acid. A low organic loading rate and the use of additional particle removal were efficient measures that reduced organic/particulate fouling. The recovery potentials for COD and phosphorous in FO concentrate were close to 100%.
