“…The empirical relation given by Turton et al 22 was used to determine the TCOM:TCOM = f 1 COL + f 2 FCI + f 3 (CUT + CRM)where f 1 , f 2 , and f 3 are multipliers given in Table 1, and COL, FCI, CUT, and CRM are the cost of operating labor, fixed capital investment, cost of utilities, and cost of raw materials, respectively. The cost of operating labor was assumed to be 1.6% of the total installation cost, 23 while the cost of raw materials and utilities was determined from the material and energy balances. The unit prices of chemicals and utilities used to calculate the economic indicators are given in Table S3 †.…”

“…Seaweed extracts are also gaining research interest as a bioplastic product due to the nature of their polymers, producing resistant durable biofilms [25,26]. Another current approach is the use of seaweed waste biomass to produce biofuels (biogas, methane, or bioethanol) since this process does not increase the atmospheric net CO 2 [27,28]. First-generation biofuels are derived from vegetable oil, starch, or sucrose, usually derived from crops.…”

The Red Seaweed Giant Gelidium (Gelidium corneum) for New Bio-Based Materials in a Circular Economy Framework

Gelidium corneum (Giant Gelidium or Atlantic agar) is a well-known red seaweed harvested for its high-quality agar content. Agar is a mixture of the polysaccharides used in the food industry as a gelling, thickener, clarifying, and stabilizer agent. The best agar quality is also used in the laboratory as bacteriological agar. Yet, in recent years, the species has been studied for many other applications. Examples of uses are pharmaceuticals, cosmetics, food supplements, bioremediation, biofuels, biofertilizers and biostimulants, biomaterials, and nanocrystals, among others. The use of this biomass, though, raises concerns about the sustainability of the resource, since this is not a cultivated species, being harvested in the wild. Thus, other uses of G. corneum biomass increase pressure on wild stocks already stressed due to climate change. However, in a biorefinery approach, a new trend is emerging, using waste biomass rather than harvested biomass to produce new bio-based materials. These are smart solutions that transform waste into innovative products, useful for various sectors of society while reducing the impact of biomass exploitation. The aim of this review paper, thus, is to address the current state of G. corneum biology, ecology, threats, its current uses and market, and the ongoing research on innovative proposals in a circular economy framework.

One of the important directions for achieving the goals of sustainable development and decarbonization is to increase the share of biofuels, including in heat supply systems. In this case, an important factor in deciding on the use of biofuel boilers is the cost of fuel, which is affected by the delivery logistics. The authors determined the impact of logistics for different types of fuel for low-power boilers (0.5 and 1 MW, burning biofuels) on LCOH. The calculations take into account the existing rates of environmental tax. The paper considers the transportation of biofuels by road to small consumers over short distances (within a radius of several hundred kilometers). The study showed that the cost of delivery of pellets from producer to consumer can be up to 20% of their cost. It is established that the transportation of a ton of pellets per 1 km increases the cost of this ton by about 1.35 UAH, therefore, the logistical component in the final cost of pellets can be significant.
