Wastewater and sewage sludge contain organic matter that can be valorized through conversion into energy and/or green chemicals. Moreover, resource recovery from these wastes has become the new focus of wastewater management, to develop more sustainable processes in a circular economy approach. The aim of this review was to analyze current sewage sludge management systems in Scandinavia with respect to resource recovery, in combination with other organic wastes. As anaerobic digestion (AD) was found to be the common sludge treatment approach in Scandinavia, different available organic municipal and industrial wastes were identified and compared, to evaluate the potential for expanding the resource recovery by anaerobic co-digestion. Additionally, a full-scale case study of co-digestion, as strategy for optimization of the anaerobic digestion treatment, was presented for each country, together with advanced biorefinery approaches to wastewater treatment and resource recovery.

Recovered Material

Wastewater has been recognized as a resource due to its large quantities, and it contains many valuable resources that can be converted into valuable material. Reusing or recovering resources from wastewater can reduce the environmental footprint of wastewater treatment, minimize the contamination and ensure the availability of valuable resources for the human being. The ultimate aim of wastewater resource recovery (WRR) is to create a sustainable and resilient community which is very relevant in Indonesia as this country experiences many natural or human-made disaster. To have an effective implementation, therefore, it is crucial to identify the barriers or supporting factors in its implementation of Wastewater Resource Recovery, which can be different for many regions. Through extensive literature studies, this study intends to review the possibility of WRR implementation in Indonesia.  This study discusses Indonesia policy/regulation about wastewater management across all-region in Indonesia, identify barriers in WRR, compares global trends of wastewater management to Indonesia practice and list wastewater resources that potentially can be recovered in Indonesia. From the review, barriers of WRR implementation in Indonesia is most probably due to the policy and regulation of wastewater management which many of them did not support the option of WRR, instead of suggesting only safe discharge option. However, some regulations have mentioned the utilization of wastewater by-product, but it is limited only to treated water utilization. Other obstacles are social acceptance and distance between recovered material supply and demand. Social acceptance includes the human perception regarding the health risk associated with wastewater by-product. Religion also could be a potential barrier that needs to be handled in the implementation of WRR. This study could give new insight into the current state of wastewater resource recovery initiative in Indonesia; thus the strategy to overcome the barriers could be designed.

Water And Wastewater

With the constant increase of population and urbanization worldwide, stress on water, energy, and food resources is growing. Climate change constitutes a source of vulnerability, raising the importance of implementing actions to mitigate it. Within this, the water and wastewater sector represents an important source of greenhouse gas (GHG) emissions, during both the construction and operation phase. The scope of this study is to analyze the GHG emissions from the current and future water supply scheme, as well as to draw a comparison between possible water reclamation with resource recovery scenarios in the town Leh in India: a centralized scheme, a partly centralized combined with a decentralized scheme, and a household level approach. Precise values of emission factors, based on the IPCC Guidelines for National Greenhouse Gas Inventories, previous studies, and Ecoinvent database, have been adopted to quantify the different emissions. Potential sources of reduction of GHG emissions through sludge and biogas utilization have been identified and quantified to seize their ability to mitigate the carbon footprint of the water and wastewater sector. The results show that the future water supply scheme will lead to a significant increase of the GHG emissions during its operation. Further, it is shown that decentralizing wastewater management in Leh town has the least carbon footprint during both construction and operation phases. These results have implications for cities worldwide.

The Future

“Wastewater treatment plants are not waste disposal facilities but are water resource recovery facilities that produce clean water, recover nutrients (such as phosphorus and nitrogen), and have the potential to reduce the nation’s dependence on fossil fuels through the production and use of renewable energy and the implementation of energy conservation.” This quote from the 2011 WEF Renewable Energy Position Statement clearly calls attention to the role of wastewater management through Water Resource Recovery Facilities (WRRF) to address the needs of the Utility of the Future. The water resources utility of the future will integrate these three major concepts of Nutrients, Energy and Water, and many cutting edge utilities are already implementing this management goal of resource recovery. This focus may initially have been internal to the water or wastewater utility, investigating sustainable energy management through energy conservation, increased renewable energy production (where feasible), and focus on overall energy management. The overall societal benefit of the resilience improvement through distributed generation is starting to be realized. The fact that a water resource recovery facility (wastewater plant) that generates its own energy can operate when the power is out is an asset during extreme events. In addition, this capacity can be coordinated with electric utilities to address peak loads and other system needs. Valuable energy products generated on-site at wastewater plants can also supply a portion of energy demand within their respective service areas. On average, the energy content of wastewater (chemical, hydraulic and thermal) is five times greater than the energy required for treatment. The most common opportunity for on-site power generation is through biogas created through anaerobic digestion. However, technologies such as gasification, pyrolysis, and incineration may be used to generate electricity or fuel. District energy systems, facilities to generate renewable diesel or aviation fuel, hydrogen fuel cells, and in-line hydropower are all being installed today. However, becoming net energy positive is not the only goal. Optimizing overall sustainability may actually require using more energy or producing less energy onsite. Treating water to higher standards is often more energy intensive. Similarly, using biogas as a transportation fuel reduces onsite power production and increased energy use is required to further process biosolids to maximize reuse potential and to recover nutrients and minerals (e.g., nitrogen, phosphorous, magnesium). A number of utilities worldwide have already taken the leap and begun this transformation towards resource recovery. While it is not practical for all water resource recovery facilities to become energy positive or neutral, all can take steps towards increasing sustainability while also improving resilience in the energy sector.
