This report consists in a study to identify the market strategy for the SALTGAE technology, which is based on the cultivation of algae for biomass valorization by using High Rate Algal Ponds (HRAP) technologies and by recycling saline nutrient-rich wastewaters from Food and Beverages industry. The objective of this report is to assess the present technical and market framework in relation to the proposed technology, with the aim to facilitate the innovation and take-off of this new solution in wastewater treatment sector.
In order to identify a roadmap towards the market development of SALTGAE process, the study investigates the state of the art of the proposed solution in the context of wastewater treatment sector and of and algae products market in Europe. The TIS (Technology Innovation System) analysis, performed in D 8.1. has identified the most relevant aspects of the SALTGAE technology in terms of technical innovation, potentials in the present and future market, and relevance among the stakeholders. As a subsequently activity, this report aims at implementing the outcomes from Technology Innovation System report provided by EUBIA, to identify a strategy towards the development of SALTGAE proposed solution in the Wastewater treatment sector. The present document will quantify the position of the proposed technical solution within the present context, assessing the readiness level of different aspects, considered as crucial for technology future development, in order to identify the existing strengths on which basing the strategy for solving most relevant barriers and weaknesses now hindering the commercial uptake.
Water is an essential resource for human life and environment, as well as source of potential economic development. Since water scarcity is a threat to human, water reuse strategies deserve major attention. Human activities are contributing to an increase of water pollution, posing a major challenge for water management across the European Union (EU). At this regard, several EU directives have been implemented, establishing among others a maximum level of pollutants allowed in wastewater discharged to natural water resources. The European standards on water quality were aimed not only at conserving the environment, but also at safeguarding people from contamination risks from poorly treated wastewater. Industries are generating big amounts of wastewater, therefore there is a need to treat the wastewater and recover nutrients prior to discharging to the environment.
Currently, several technologies exist for treatment of saline wastewater. An innovative membrane technology, membrane distillation, is capable of desalting highly saline water. It is used for desalination of water and treatment of industrial wastewaters. However, the obstacles to implement innovative wastewater treatments are numerous. First, the adoption decision regarding environmental technologies depends on a large number of determinants that are context-specific and interact mutually. Secondly, the costs and rewards of sustainable innovation are distributed unevenly across the involved actors and communities. Their deployment involves multiple and institutionally diverse stakeholders that express different interests, and may have conflicting objectives (EIP Water, 2014). This multifaceted landscape introduces significant challenges for those who aim at easing the dynamic efficiency of the sector. The adoption of new technologies in the water and wastewater industries is becoming a key issue in public debate and policy arenas (EC 2013; EIP Water, 2014).
This debate is particularly important on the food and beverage (F&B) industries due to the high content of salinity contained on the wastewater. The accumulation of salt Na+ in industrial effluents is considered as a new challenge for anaerobic wastewater treatment. The large content of biodegradable matter and high salt levels of this waste stream requires complex sequences of physicochemical and biological treatment processes to meet EU standards for the management and protection of the water environment. Associated costs for water treatment for the 15,000 European SMEs, which represents 5% of the total F&B industry, are estimated at €4.46 billion and can represent up to 14% of companies’ annual turnover. This is often perceived as unaffordable and non-compliance presents environmental risks. Therefore, some SMEs discharge the wastewater without prior treatment, causing severe damage to the environment. Salinity can cause eutrophication of water, salination and sodification of the soil. The high costs of saline wastewater treatment are due to the secondary and tertiary treatments, which are carried out using different types of bacteria for organic matter decomposition and nitrifiers/denitrifiers for N elimination and polyphosphate accumulating organisms (PAOs) for P removal.

The aim of task 7.1 is to develop a system model that includes the necessary data and information required to implement tasks 7.2 Techno-Economic evaluation (viability study), 7.3 Environmental assessment and 7.4 Social assessment (Figure 1). The life cycle inputs and outputs as well as components of the treatment systems will be modelled and clear system boundaries and scenarios to be evaluated will be defined. Interactions and exchanges with external systems such as nature, energy systems and society will be included in the model. Benchmark systems will also be defined, which will serve as a reference to which the SALTGAE technology will be compared to in terms of performance.
The first task of WP1 (Halotolerant Cultures), led by FPTP, was to set-up lab-scale microalgae/bacteria systems in different saline wastewaters. Three saline wastewaters were chosen in the project framework: tannery, fishpond and cheese whey/dairy wastewaters, since the final goal of the project is to respond to the request of a wide range of industrial sectors, such as leather, food processing and land-based aquaculture.
The aim of D7.2 is to examine the environmental and economic performance of the installed demonstration sites, as well as selected algae valorization routes. The study should provide information for technology developers on the implications of design choices. A screening Life Cycle Assessment (LCA) and a Life Cycle Cost Analysis (LCCA) have been carried out to study the environmental impacts and cost incurred in the life cycle of two demonstration sites, namely KOTO in Slovenia and Archimede in Italy. Furthermore, only some valorization routes have been examined, namely composites and animal feed. A screening LCA and LCCA means that the study includes a combination of site-specific data, generic data from literature and databases, and some rough assumptions. Therefore, this deliverable is an interim report and the results presented need to be interpreted carefully. The estimated values and assumptions will be refined when further operational data from the consortium becomes available, and final conclusions will be reported in deliverable D7.3.
