“…The limiting parameter in all the alternatives presented is the COD. This parameter is commonly used to study the reuse of industrial effluents (Mohammadnejad et al, 2012;Xu et al, 2015;Mughees and AlAhmad, 2015;Mohammadnejad et al, 2011;Feng et al, 2009), and this evaluation confirms the relevance of this parameter for the reuse in a petrochemical process. …”

“…Recently, mass integration was implemented to minimize freshwater consumption in a yeast company through the optimization of the water utilization network using pinch methodology. This allowed for the recycling of 173,480.4 t/year of water within the system, demonstrating that 27% of freshwater usage can be saved [23].…”

Bioadsorbents based on biopolymers modified with magnetic nanoparticles stand out for being non-toxic, effective, and easy to recover. Thus, the objective of the present work was to carry out a computer-aided environmental evaluation of the industrial-scale production of bioadsorbents from chitosan modified with iron nanoparticles and functionalized with thiourea as a chelating agent plus mass integration. The plant simulation was carried out in Aspen Plus, and for the mass integration of the process, a pinch analysis was used to determine the minimum target fresh and residual water amount, assuming two process stages: (1) the synthesis of magnetite nanoparticles, and (2) the production of chitosan-based bioadsorbents. The environmental assessment was performed using the waste reduction algorithm (WAR). The potential environmental impact (PEI) was quantified, taking into account the impact of the products and energy, obtaining a value below zero of −0.78 PEI/kg of the product. The photochemical oxidation potential (PCOP) stood out as the category with the greatest impact, mainly related to the use of ethanol during washing. The categories related to toxicological impacts (HTPI, HTPE, TTP, and ATP) had lower values than those related to atmospheric impacts (GWP, ODP, PCOP, and AP). The mass integration of the process resulted in fewer impacts in the HTPE category, as a consequence of the decrease in NaOH in the residual streams and the release of 0.297 PEI/kg of product in the ATP category caused by the presence of Al(OH)₃. It can be concluded that the mass integration managed to reduce up to 51% of the freshwater used in the processes, and it is a useful tool, as it slightly decreased the total potential impacts.

“…Among them, the stock prices of environmentally friendly water resources enterprises have increased year by year, while the stock prices of non-environmentally-friendly water resources enterprises have not been affected by policy dividends. However, business person from water supply enterprises participating in the disclosure of water price cost said that, with the increase of water shortage, the price of water resource fee may be doubled in the future [12,13]. In view of the fact that water price is related to people's livelihood, it still needs to be weighed by the competent authorities [14,15].…”

From the perspective of economics, blockchain is simply an Internet, which can meet the needs of the sharing economy to a certain extent. With the development of the world, blockchain technology has developed in an explosive growth. At present, the systematic research on blockchain technology at home and abroad is still in its initial stage, mainly focusing on the application prospect, especially in the fields of traditional finance and digital currency. The development of environmentally friendly water resources enterprises has the support background of the country, and the financial impact of blockchain technology also affects environmentally friendly water resources enterprises. In order to explore the development of blockchain technology in water resources protection, based on the advantages and application status of blockchain technology, this paper firstly constructs a supply chain financial system model of water resources enterprises based on blockchain and secondly analyzes the financial environment of seven water enterprises in China by constructing a financial environment evaluation model. The results show that Chongqing Water has the highest target degree of 0.76 and target level of 3, indicating that the enterprise has good adaptability and maintains the stability of financial environment under the influence of blockchain technology. Furthermore, the asset valuation of Chongqing Water is analyzed by Monte Carlo method. The results show that, under the blockchain financial model, the fierce competition in the wealth management products market will make issuers lose their dominant position in pricing and reduce profits in order to attract investors.
