The Cost

Commercialization of concentrating solar power (CSP) technologies require the development of advanced reflector materials that are low cost and maintain high specular reflectance for extended lifetimes under severe outdoor environments. During the past 9 years, the National Renewable Energy Laboratory (NREL) has funded Science Applications International Corporation (SAIC) in McLean, Virginia, to develop a promising low-cost advanced solar reflective material (ASRM) combining the best of both thin-glass and silvered-polymer reflectors. The alumina (Al2O3) coating is deposited by ion-beam-assisted physical vapor deposition (IBAD). Materials undergoing testing demonstrate excellent durability under accelerated and outdoor weathering. To help commercialize the technology, NREL had a cost analysis performed incorporating realistic web coating assumptions and the technical improvements made in the ASRM. The biggest process cost items are the alumina and machine burden (which collects the cost of the building and office staff). The switch from a polyethylene terethaphalate (PET) to a steel substrate for the ASRM is a significant contributor to the cost. The cost of high-purity alumina should drop from $400/kg to $200/kg when purchased in 20-kg quantities. Alumina deposition rate then becomes the critical cost driver. In a previous study, deposition rates above 100 nm/s were not examined, but deposition rates greater than 100 nm/s are being used routinely for thin alumina coatings deposited on commercial web-coaters as barrier coatings. In addition, multiple (2–3) Al2O3 IBAD zones can be used in one roll-coating machine to deposit thicker alumina at a lower web speed. This means that with increasing deposition rate and/or multiple zones, the total production cost of the SAIC ASRM with 1-μm thick Al2O3 on PET will meet both the 1992 cost goal of $10.76/m2 ($1/ft2) and the equivalent cost goal of $13.79/m2 ($1.31/ft2) when the 1992 cost goal is corrected for inflation. There is a minimum deposition rate needed to reach the cost goal and a maximum deposition rate related to the number of zones after which no significant cost gains are observed. These asymptotic total production costs are $8.06/m2 ($7.39/m2 excluding substrate) for a large commercial web-coating company and $7.62/m2 ($6.94/m2 excluding substrate) for a smaller company. As can be seen by these numbers, the $10.76/m2 cost goal can be reached, but the cost of the substrate is still a major consideration. In addition, the width of the web was increased from 600 to 1200 mm, which decreased the asymptotic total production costs. The results of the cost analysis will be described.

This paper addresses the enhanced removal of pharmaceutical compounds (PhCs), a family of contaminants of emerging concern, and effluent organic matter (EfOM) in water reclamation by powdered activated carbon/coagulation/ceramic microfiltration (PAC/cMF). Four chemically diverse PhCs are targeted: ibuprofen (IBP), carbamazepine (CBZ), sulfamethoxazole (SMX) and atenolol (ATN). Pilot assays (100 L/(m2 h), 10 mg Fe/L) run with PhC-spiked sand-filtered secondary effluent and 15 mg/L PAC dosed in-line or to a 15-min contactor. They showed no PAC-driven membrane fouling and +15 to +18% added removal with PAC contactor, reaching significant removals of CBZ and ATN (59%–60%), SMX (50%), colour (48%), A254 (35%) and dissolved organic carbon (DOC, 28%). Earlier long-term demo tests with the same pilot proved PAC/cMF to consistently produce highly clarified (monthly median < 0.1 NTU) and bacteria-free water, regardless of the severe variations in its intake. A detailed cost analysis points to total production costs of 0.21 €/m3 for 50,000 m3/day and 20 years membrane lifespan, mainly associated to equipment/membranes replacement, capital and reagents.

In this study we were studying the question whether walnut production under domestic natural and economic circumstances shall be considered a profitable activity or not. Our partial objective is to determine, what level of natural inputs and production costs are required for walnut production, what yield level, selling price and production value can be attained, what level of profitability, rentability and efficiency may production have, is the establishment of a walnut orchard profitable on the entire lifespan of the plantation, and the production of which is more efficient: the dry shelled walnut production requiring postharvest activity or the raw, shelled walnut without postharvest activities. In this study, comparison of two systems is conducted. First version: producer establishes a walnut plantation and sells walnut raw and shelled. Second version: producer also invests into a drying facility, and in this case the end product is the dry, shelled walnut. If the producer sells walnut right after harvest in a raw bulk, total production costs in productive years reaches 974,011 HUF/ha. Attainable yield is 2.63 t/ha with 396.3 HUF/kg selling price, therefore the profit is 138,258 HUF/ha with 14.19% cost-related profitability. In the case when the producer sells dried, shelled walnut, production costs are 25% higher compared to that of raw walnut due to the cost of drying. By calculating with the postharvest loss, average yield is 1.84 t/ha, however, its selling price is way higher (882.84 HUF/kg), therefore the profit per hectare reaches 475,496 HUF with 39.01% cost-related profitability. Thus it can be stated that walnut production in an average year may be profitable even without postharvest, but efficiency is improved significantly when the producer sells the products dried. Investment profitability analysis revealed that production of raw, shelled walnut is not economically viable, since the plantation does not pay off on its entire lifespan (30 years), while walnut production with postharvest is efficient and rentable, since both net present value (NPV) and internal rate of return (IRR) showed more favourable values than in the previous case, and the orchard pays off in the 21th year after establishment.

Animal husbandry has a longstanding tradition in Serbia, and the production of milk and dairy products has a rich legacy. Cow?s milk is used in the manufacture of all kinds of dairy products. Annual global cheese production is about 20 million tons, with cattle milk cheeses produced in large-scale processing plants constituting about 80% of that production. In Serbia, leaders of milk production are small family dairy farms, which contribute 92% of total production, while dairies with large capacity dominate in milk processing. There are 211 milk processing plants of varying capacities in Serbia. The largest amounts of milk are processed by dairy plants 'Imlek' and 'Subotica', while 188 small-scale dairies process 20% of total milk. The subject of this paper is the analysis of the economic indicators of production of semi-hard and hard cheeses in small-capacity dairies in Serbia. To determine the level and structure of production costs of dairy products, the analytical calculation method of per unit processing costs has been used. The study has revealed that the cost price of semi-hard and hard cheeses in small-capacity dairies amounts to 3.33 ?/kg. With 90.83% in the structure of total costs of processing the milk into cheese, the cost of raw materials has the largest share, followed by labor costs with 6.54%. For small-capacity dairies to be able to compete with larger dairies, both in product quality and price, it is crucial to continuously monitor and minimize production costs.

Spine Number

Spininess is characteristic of many Malus species, especially American crabapple and Malus baccata L. Spininess often is present on rooted stoolshoots of commercial apple rootstocks (M.9, M.26, MM.111, and MM.106) and some rootstocks from the Geneva Breeding Program. This undesirable characteristic makes liner production costly and laborious. It is estimated that the cost of manual removal of spines amounts to ≈20% to 25% of total production costs. To counteract spininess, the stoolshoots of excessive spiny rootstock selections [74R5M9-760 (T/1), 74R5M9-707 (T/2), and 75R5M9BR-521 (T/3)] were chemically treated while growing at stoolbed. Chemical treatments consisted of single sprays of nontranslocated growth regulators Tamex (a.i. butralin) or Tamex AG (a.i. butralin + fatty alcohols C8- C10), and commercial auxin formulation (Tre-Hold A-112). Tamex AG and A-112 at applied rates brought about some phytotoxicity effects while Tamex did not. On average, Tamex application (1000, 2000, and 4000 ppm) reduced spine number to ≈80%, 68%, and 84% of T/1, T/2, and T/3 control plants, respectively. However, Tamex at 4000 ppm reduced the number of spines to 57% and 60% of control T/2 and T/3 plants, respectively, without any detrimental side effects. A parallel greenhouse experiment is being performed using commercial M.26 and Geneva 30 apple rootstocks.

The MENA theatre is situated in one of the most fascinating locations of the world, the Middle East and North Africa. It represents, along with the Balkans-Caucasus, the only existing land corridor that connects three continents. It also holds over a half of the world’s proven oil-gas reserves (56 percent - oil, 48 percent - gas). Furthermore, the Gulf OPEC states and Libya have by far the lowest costs of oil extraction, thanks to the high crude purity (measured by overall properties such as the state of aggregation, excavation gravity, viscosity, weight, sulfuric content and other contaminants) which simplifies and reduces the cost of the refinement process. These petrol-exporters also enjoy the close proximity to open warm seas for low-cost, fast and convenient overseas shipments. Hence, the costs per barrel of crude for Libya and the Persian Gulf states are under US$ 5; for other OPEC members, below US$ 10. This is in a sharp contrast to countries such as the US, Russia, Norway, Canada and many others that bear production costs of several tens of US$ per barrel, according to the International Energy Agency (IEA). Therefore, it is an absolute imperative for the external/peripheral powers to dominate such a pivotal geo-economic and geopolitical theatre by simply keeping its centre “soft,” and pre-empting, preventing or hindering any emancipation that might come through any indigenous socio-political modernisation. This is the very same imperative that has remained a dominant rationale of inner European and Asian machtpolitik for centuries.

Titanium and titanium alloys are the materials of choice for many industrial applications because of their attractive combination of low density, good mechanical properties, and high corrosion resistance, and titanium is the fourth most abundant metal in the earth crust (0.86 % by weight) behind aluminum, iron, and magnesium. However, titanium and titanium alloys are not widely. The reason for this is the high cost of titanium and titanium alloys! The cost gap for titanium and titanium alloys widens when they are used for fabricating components and structures. Consequently, much effort has been expended to reduce the cost of titanium and titanium alloys. In conjunction with the University of Waikato, Titanox Development Limited-New Zealand has been successful in creating a modified novel process to produce TiAl based alloy powders with different particle sizes and compositions at low cost. The process offers several benefits to the titanium industry the most significant one of which is that it displays the potential to significantly reduce the commercial production costs of Ti-Al based alloys. This paper describes the Titanox Development Limited technology in brief, and shows how it can economically produce titanium alloy powders for different industrial applications and making titanium alloys affordable. The process has been disclosed in a PCT (Patent Corporation Treaty) application which was approved in 2004 [1], and the related patent applications either have been approved or are being filed in different countries.
