BC Technologies for Addressing Climate Challenges

Technological innovation has historically played a key role in addressing climate challenges. This chapter investigates the intersection of bioconvergence technologies and climate challenges, with the aim of not only adopting existing solutions but also identifying how bioengineering paradigms facilitate novel approaches to these issues.

Through a review of significant technologies, this chapter considers how this multidisciplinary interface may yield a high-quality, responsive, and sustainable solutions to urgent climate exigencies that necessitate immediate and innovative interventions. Additionally, it will be demonstrated that climate change itself engenders opportunities for the advancement and utilization of bioconvergence technologies, functioning not solely as a response mechanism but also as an active design instrument for complex and disruptive environmental contexts.

The preceding two chapters are based on research conducted by the Innovation Authority, which encompassed a systematic mapping of technological requirements within the climate sector, as well as the formulation of a taxonomy specifically pertaining to bioconvergence. In the subsequent phase of the research, concrete linkages were examined between the technologies identified in the taxonomy (across various levels) and their environmental applications. The connections identified were compiled into an interactive knowledge map, which links concepts and technologies from the bioconvergence domain with a diverse array of climate challenges. A connection was included in the map only when it exhibited clear conceptual and applied relevance, substantiated by a minimum of five peer-reviewed scientific articles. This map, which encompasses hundreds of research-based connections, facilitates bidirectional exploration – both from the technological and from climate needs perspectives. This chapter builds upon the findings of the map and presents focused examples that illustrate the application potential and impact of integrating these two domains – from technology to necessity, and from necessity to solution.

The next section presents a selection of bioconvergence technologies – biochips, synthetic biology, and living materials – to exemplify how these technologies can address a range of climate needs.

Biochips

Biochip technology was initially developed to address medical and biological needs; however, it has progressively evolved into an advanced platform for environmental applications. This transformation is attributed to biochips’ miniaturization, high sensitivity, and capacity for integration into digital systems, enabling precise and continuous monitoring of environmental conditions¹. For instance, biochips can be implemented in air quality monitoring systems to detect biological pathogens or volatile chemical compounds in urban and industrial settings; in water monitoring stations, for the early identification of heavy metals, industrial pollutants, or abnormal biological processes; and in ecological systems such as lakes, coral reefs, or smart agriculture, to measure microbial, biochemical, and physical parameters in real time². Another significant application is within the domain of livestock management, where miniature biochips are implanted in the bodies of animals, including cows, sheep, and goats, to facilitate continuous monitoring of health and behavioral parameters³. These biochips incorporate sensors that assess body temperature, heart rate, movement, breathing rate, and, in some instances, the composition of substances in sweat or saliva. The data collected allows for the early detection of physiological stress, diminished health function, or initial signs of disease progression. In certain scenarios, the biochips also facilitate the direct identification of pathogens, thus providing an early warning regarding potential outbreaks within the herd. This synthesis of physiological monitoring and microbial identification renders the technology an essential instrument for disease prevention, the assurance of animal welfare, and the minimization of prophylactic antibiotic usage. Furthermore, the capability of connecting biochips to Internet of Things (IoT) networks and artificial intelligence systems enhances their functionality as data-driven decision-making tools in dynamic environmental conditions⁴.

Synthetic Biology

Synthetic Biology, which seeks to design novel biological systems or modify existing natural systems, offers breakthrough solutions for addressing climate challenges. For instance, engineered microorganisms and algae are currently under development with the capacity to absorb and sequester carbon dioxide from the atmosphere, while also serving as raw materials for renewable biofuels or biodegradable bioplastic alternatives to fossil products⁵. Concurrently, synthetic biology facilitates the engineering of bacteria capable of degrading organic pollutants and heavy metals, thereby offering applications in environmental remediation, particularly bioremediation of soils, waterways, and industrial sites affected by flooding, pollution, or desertification⁶. Additionally, this field provides viable solutions to the issue of food security through the development of plant varieties that exhibit resilience to drought, extreme temperatures, or poor soil conditions, thereby adapting to the impacts of climate change⁷.

Living Materials

The domain of Living Materials represents an innovative paradigm in material science, wherein living cells or active biological components are integrated within a structural matrix, enabling environmental responsiveness, self-repair, and advanced biological functions over time. These materials are presently being developed to address a range of needs, particularly within the construction and environmental sectors. Notable examples include smart concrete that houses bacteria capable of secreting calcium to seal fissures⁸, as well as humidity and temperature regulation systems predicated on biological reactions⁹. Additionally, living materials play a role in urban water management through mechanisms such as biosorption, living barriers to flooding, and the restoration of soils compromised by erosion or pollution. A recent illustration of this is the employment of fungal mycelium hydrogels, an engineered material that incorporates living fungal cells to provide both structural integrity and environmental interaction¹⁰. Moreover, certain materials exhibit the capacity for continuous carbon fixation through self-photosynthesis or controlled biological reactions¹¹. The field of living materials is also extending into the domains of apparel and textiles, with advancements in smart biological materials designed for protection against extreme environmental conditions, alongside the creation of biodegradable clothing as part of the shift toward a circular economy¹².

The examples delineated herein exemplify the versatility of bioconvergence technologies and their potential for integration across various environmental disciplines. However, to attain a comprehensive understanding of their potential value, it is imperative to examine the obverse: how significant climate challenges are fostering new opportunities for implementing bioconvergence principles. The subsequent section will explore several critical environmental needs – namely, water purification, renewable energy generation, and environmental monitoring – and will illustrate how these needs can be effectively addressed through the application of bioconvergence technologies.

Water Purification

Water pollution constitutes one of the principal environmental challenges of the contemporary era. Factors such as industrialization, intensive agriculture, inadequate management of urban wastewater, and the infiltration of pharmaceuticals and microplastics, all contribute to the exacerbation of pollutant loads in both freshwater and saltwater sources. Additionally, the impacts of climate change, including heat waves, flooding, and inundation, further amplify the dissemination of pollutants in aquatic environments.

A notable technology that encapsulates the principles of bioconvergence in the domain of water remediation is the Algal-Bacterial Consortium. This biological engineering system integrates microalgae and bacteria into a symbiotic culture specifically designed to remediate contaminated water¹³. In this symbiotic interaction, algae produce oxygen via photosynthesis, which subsequently supports bacterial activities that facilitate the breakdown of organic pollutants, nutrients (nitrogen and phosphorus), and heavy metals. Moreover, these systems can also mitigate antibiotic resistance genes (ARGs) by degrading free DNA fragments in water or by suppressing populations of resistant bacteria through biological competition and the establishment of biochemical conditions unfavorable to their proliferation. These systems are currently being constructed through the deployment of computational tools, sensors, and models of cellular interactions, allowing for the optimal design of the consortium under varying environmental conditions.

For instance, an engineered consortium comprising Chlorella vulgaris and Bacillus licheniformis exhibited a reduction exceeding 98% in nitrogen concentrations, accompanied by a substantial decline in the prevalence of antibiotic resistance genes¹⁴. Furthermore, this technology has led to the generation of biomass suitable for the production of biofuels, fertilizers, or biodegradable plastic alternatives. Studies have also indicated a reduction in N₂O emissions relative to conventional purification methods, thereby highlighting its contribution to the abatement of greenhouse gas emissions.

Another promising technology for addressing the water purification challenge is Microbial Electrolytic Carbon Capture (MECC)¹⁵. In this methodology, wastewater laden with organic matter is introduced into a microbial electrolytic cell, where bacteria decompose pollutants while simultaneously generating an electric current. This process results in the removal of organic compounds, the reduction of nutrients (nitrogen and phosphorus), and the neutralization of various pollutants – including pathogens – with a high degree of efficiency. Additionally, MECC facilitates the biochemical fixation of carbon dioxide. The electrochemical reactions in the cell generate basic conditions (high pH) in the cathode region, enabling the fixation of CO₂ as mineral salts (such as calcium carbonate), thereby diminishing its atmospheric concentration. Distinct from alternative biological systems, carbon fixation occurs concurrently with water purification while producing an energetic by-product, such as hydrogen. Through the integration of biological, chemical, and engineering knowledge, MECC presents a dual solution to both aquatic environmental concerns and emission challenges.

Another innovative approach with significant potential for the treatment of persistent water pollutants, such as per- and polyfluoroalkyl substances (PFAS), involves the utilization of genetically engineered bacteria¹⁶. These substances exhibit exceptional stability and resistance to degradation, thereby presenting substantial difficulties for conventional water purification techniques. Employing synthetic biology enables the design of bacteria capable of degrading or neutralizing such compounds by integrating metabolic systems with tailored biochemical reactions.

Renewable Energy

One of the critical areas in addressing the climate crisis is the production of renewable energy that does not rely on fossil fuels. In this context, it is essential to develop efficient, accessible, and clean energy sources – those that do not emit carbon and possess the capability to operate on a large scale under varying environmental conditions. An illustrative example is the development of bionic leaves – artificial systems designed based on the principles of photosynthesis, which emulate the ability of plants to convert sunlight, water, and carbon dioxide into renewable fuels¹⁷. Bionic leaves replicate the natural photosynthesis process while enhancing its efficiency and adaptability. They comprise a combination of advanced electrodes, catalysts based on non-precious metals, and engineered microorganisms such as Ralstonia eutropha, which absorb the byproducts of water decomposition (hydrogen and oxygen) and utilize them to produce energy-dense carbon compounds such as isopropanol or butanol. In contrast to plants, bionic leaves do not necessitate soil or irrigation, thereby enabling operation in areas unsuitable for traditional agriculture. Furthermore, their conversion process is markedly more efficient; according to research conducted at Harvard University, a bionic leaf system was capable of fixing carbon and generating liquid fuel at a rate ten times higher than that of natural photosynthesis.

Another technology in the renewable energy sector involves the production of biological hydrogen utilizing engineered microalgae. Hydrogen is regarded as one of the cleanest and most promising fuels for a low-carbon energy future; however, the majority of its industrial production currently depends on fossil sources. Genetic engineering of microalgae, such as Chlamydomonas reinhardtii, enables the enhancement of the activity of hydrogenase enzymes responsible for hydrogen production within cells, prolongs the duration of hydrogen production (even under relatively aerobic conditions), and may increase the efficiency of the process¹⁸. This process occurs within photobiological reactors designed to regulate light, heat, and flow conditions to optimize the reaction. Furthermore, the entire system captures carbon dioxide from the environment – typically from industrial sources – and transforms it into a precursor for energy production. This creates an integrative system that facilitates the generation of green fuel from renewable resources.

Another technology that exemplifies the potential of bioconvergence in the energy sector is Microbial Fuel Cells (MFC)¹⁹. Despite the similarity in bioelectrochemical mechanisms to the aforementioned MECC, MFC technology provides a distinct direction, focusing on continuous energy production from biological sources. In this context, microorganisms decompose organic matter while releasing electrons; however, unlike MECC, electricity is generated from diverse sources of biological waste – including wastewater, food fermentations, or agricultural biomass. Additionally, MFCs can operate not only in an aqueous medium but also in semi-moist substrates or relatively solid environmental systems, such as contaminated soils. These cells are specifically designed for continuous operation at low power levels, rendering them particularly suitable for environmental sensors, autonomous monitoring systems, or devices in remote areas. The primary advantage of MFC over MECC lies in its flexibility, simplicity, and the potential to deploy small, cost-effective systems in various settings. These characteristics position MFC technology as a promising candidate for distributed applications, particularly in rural or developing regions, where infrastructure is limited but local potential exists for energy production from available organic waste.

Environmental Monitoring

Among the systems necessary for addressing climate change, precise and continuous environmental monitoring has emerged as a critical infrastructure. The phenomena of heat waves, floods, industrial pollution, and soil erosion, contribute to increased volatility and uncertainty within the environmental domain. To manage these risks and formulate informed responses in real time, high-quality and accessible information from the field is essential. Nevertheless, conventional monitoring systems, typically reliant on chemical sensors and static measuring stations, face challenges in adapting to changing conditions, covering extensive geographical areas, or detecting complex biological and organic materials²⁰

Bioconvergence facilitates the advancement of sensitive, adaptive, and intelligent sensing systems. A notable example in the realm of environmental monitoring is the creation of cell-free DNA-based biological sensors (cell-free biosensors)²¹. These systems employ synthetic DNA segments and protein translation components, programmed to identify specific contaminants – such as heavy metals, antibiotics, or industrial residues – and generate a measurable response, often manifested as a color change or fluorescence. Unlike traditional sensing cells, these systems do not incorporate living organisms, rendering them less sensitive to extreme fluctuations in environmental conditions (e.g., temperature, acidity, oxygen levels). These sensors are capable of detecting contaminants at minimal concentrations within minutes and are applicable in field settings, even in remote locations. Current developments in this area include the utilization of paper, gels, or mobile electrodes, presenting a novel model for accessible, portable, and cost-effective biological sensing, as an integral element of comprehensive environmental monitoring infrastructures.

Another technology employs genetically engineered microorganisms to detect and report biochemical changes in soil, including the presence of organic pollutants, fuel spills, variations in pH or oxygen levels, and early indicators of desertification²². These cells can be integrated with genetic sequences that are responsive to specific environmental stimuli and programmed to generate a measurable signal, such as luminescence or a shift in metabolite concentration. The uniqueness of this methodology resides in its capacity to facilitate monitoring “from within” the soil itself in a continuous and autonomous manner, while adapting to fluctuating conditions and enabling data transmission to digital systems. When combined with Internet of Things (IoT) networks and artificial intelligence, this approach generates a system capable of providing profound environmental insights in real time.

Another groundbreaking technology in environmental monitoring utilizes biohybrid robots based on mycelium – a web of fungi serving as an active biological sensor²³. Recent investigations suggest that mycelium reacts to environmental stimuli, including humidity, temperature, pH variations, and the presence of organic pollutants and metals, through alterations in electrical signals conveyed through its cellular network. The integration of mycelium networks into robotic systems, whether as components of a living robotic shell or functioning as internal sensors, enables robots to biologically “sense” their environment and convert electrical signals into digital data.

This chapter elucidated how bioconvergence may serve as a foundation for the development of innovative climate solutions, achieved by both extending the applications of existing technologies as well as by addressing complex environmental needs that necessitate a combination of technological efficiency and systemic adaptation. The examples provided exemplify living, adaptive, and dynamic technologies – biologically engineered systems that operate under varying terrain conditions, respond in real time, and exhibit self-sustaining capabilities over time. Consequently, it becomes evident that bioconvergence is not merely a groundbreaking technological field nor solely a supportive domain for addressing climate change; rather, it functions as an integrative platform for designing systemic responses to an ongoing, complex, and dynamic crisis.
