“…When kiln's capacity increases from 20,000 to 100,000 bricks per batch, PBP reduces from 7.93 to 4.02 years. Aguado et al (2021) also reported a similar trend of PBP in the implementation of gasifier in agricultural food processing sector. Normally, the increase in capacity or size of a renewable energy system reduces the rate of capital and running costs (Beno and Edwin 2020; Glivin et al 2018), which is also seen in Figs.…”

Direct firing of biomass in conventional clay brick manufacturing process aggravates deforestation, climatic change, poor economic benefits to rural industries, and health issues to the public. To overcome such drawbacks, adaptation of ecofriendly energy sources, implementation of advanced technologies in energy conversion systems and systematic studies on economic benefits are mainly focused in recent times. The utilization of biomasses through various gasification technologies can improve the energy efficiency and economic advantages of brick production. To successfully introduce renewable energy systems and new technologies in rural areas, a number of research studies have experimented and also succeeded in predicting the technical feasibility and cost benefits. Likewise, this paper reports the techno-economic analysis of producer gas (PG) fired brick kilns using pertinent parameters of evaluation involved in the manufacturing of bricks. In this study, the common biomasses available in the region were effectively used to produce PG. Besides finding the technical aspects of bricks produced through this method, the parameters needed for economic study were found from a prototype experimental study. The economic parameters to use agriculture and forestry biomasses such as Coconut Shell (CS), Rice Husk (RH), Rubber Wood (RW) and Rubber seed kernel shell (RSKS) in conventional industries for a capacity of twenty to one hundred thousand bricks per batch were predicted. The studies revealed that the quality of bricks produced from the proposed method could meet ASTM standards. The savings in the running cost of the proposed system led to 4-8 years payback period. The maximum internal rate of return was found from the system which had RSKS as feedstock.

“…Gasification plants can be installed at the olive oil mills in self-consumption mode, in order to reduce the electricity costs. This solution require regular maintenance, then enabling "the creation of a permanent part-time technical job" [53]. Presenting a high content of carbon and hydrogen, and conversely a low level of ash and moisture, with a considerable heating value, exhausted olive pomace is considered to be the most appropriate olive oil by-product for feeding the gasifier plants [53], also thanks to its massive production rate and thus high-volume availability.…”

“…The biochar is a very interesting output of processes of pyrolysis, which offers a very important and yet unknown potential for farmers. Due to its macroscopic structure and composition, it acts as an amendment to the soil, returning the carbon captured by olive trees to the soil and providing numerous benefits in terms of plant growth, water and nutrients retention, soil erosion contrast, microbial life improvement [53]. Moreover, it constitutes a good "remediation co-product for very old plantations" [108].…”

Available Pathways for Operationalizing Circular Economy into the Olive Oil Supply Chain: Mapping Evidence from a Scoping Literature Review

et al. 2021

Circular economy (CE) is increasingly seen as a promising paradigm for transitioning agri-food systems towards more sustainable models of production and consumption, enabling virtuous and regenerative biological metabolisms based on strategies of eco-efficiency and eco-effectiveness. This contribution seeks to provide a theoretical and empirical framework for operationalizing the CE principles into the olive oil supply chain, that plays a central role in the agroecological systems of the Mediterranean region. A scoping literature review has been conducted in order to identify the available pathways so far explored by scholars for reshaping the olive oil supply chain from a circular perspective. The analyzed literature has been charted on the base of the circular pathway examined, and according to the supply chain subsystem(s) to which it refers. Results are discussed highlighting the main issues, the technology readiness level of the available pathways, the prevailing approaches and knowledge gaps. A synthetic evidence map is provided, framing visually the scrutinized pathways into the Ellen MacArthur Foundation’s CE ‘butterfly’ graph. The work is intended to be a valuable baseline for inquiring how circularity can be advanced in the specific supply chain of olive oil, and which are the strategic opportunities, as well as the barriers to overcome, in order to foster the transition.

“…Weather conditions not only affect electricity production from both solar and wind but also directly impact electricity demand [1]. The highest demand is observed in the summer and the lowest demand usually occurs in the spring [2]. Similarly, demand varies across the day; it is higher during working hours, i.e., from morning until evening [3,4].…”

Techno-Economic Assessment and Operational Planning of Wind-Battery Distributed Renewable Generation System

Electrical energy and power demand will experience exponential increase with the rise of the global population. Power demand is predictable and can be estimated based on population and available historical data. However, renewable energy sources (RES) are intermittent, unpredictable, and environment-dependent. Interestingly, microgrids are becoming smarter but require adequate and an appropriate energy storage system (ESS) to support their smooth and optimal operation. The deep discharge caused by the charging–discharging operation of the ESS affects its state of health, depth of discharge (DOD), and life cycle, and inadvertently reduces its lifetime. Additionally, these parameters of the ESS are directly affected by the varying demand and intermittency of RES. This study presents an assessment of battery energy storage in wind-penetrated microgrids considering the DOD of the ESS. The study investigates two scenarios: a standalone microgrid, and a grid-connected microgrid. The problem is formulated based on the operation cost of the microgrid considering the DOD and the lifetime of the battery. The optimization problem is solved using non-linear programming. The scheduled operation cost of the microgrid, the daily scheduling cost of ESS, the power dispatch by distributed generators, and the DOD of the battery storage at any point in time are reported. Performance analysis showed that a power loss probability of less than 10% is achievable in all scenarios, demonstrating the effectiveness of the study.
