three times as much electricity per square foot as an office building. much of the energy use responsible for a labs large environmental footprint comes from plugload equipment including freezers, incubators, computers, and other technologies which are necessary to support laboratory research. to determine how much energy could potentially be saved if a laboratory adopted basic energy conservation practices, quentin gilly of harvard medical schools drosophila rnai screening center conducted a case study comparing bench top equipment energy use before and after the adoption of intervention strategies in marc kirschners lab in the department of systems biology. although the kirschner lab already practiced some energyconscious behaviors, quentin anticipated that they would discover some room for improvement. see full list on green.harvard.edu for the study, quentin partnered with the kirschner lab to assess bench top instruments using a modletenergy monitoring device which sent data via wifi to a local computer in 15 minute intervals over the duration of the preintervention study. after this data was exported and analyzed, quentin was able to approximate the baseline energy consumption for these instruments under typical use. the baselines spanned from an average of 96 watts per day for the least energyintensive drummond pipette charger, to an average of 9,678 watts per day for the largest energy hog: a biorad thermocycler. although some equipment was only turned on when needed, including a water bath and a rocker, several of the instruments that ran on a regular basis appeared to be good candidates for potential energy reduction. the study lasted for a total of three weeks, with the first two weeks devoted to collecting baseline data and the third week focusing on energy reduction potential after adopting various int see full list on green.harvard.edu the preliminary results were quite promisingover the span of five days, the lab equipment showed significant energy reductions averaging 51.6%, with some equipment, such as the energyintensive biorad thermocycler, reducing its energy consumption by as much as 70%. quentins case study highlights how simple, energysaving practices can help a laboratory significantly maximize its energy reduction potential. the challenge is effectively communicating and motivating all lab members to take part in the initiative. as quentin notes: it is not until an institution can recruit everyone involved before the true potential of laboratory sustainability can be revealed. the case study data for the kirschner lab will help show lab members how simple social engineering techniques, like posting signs on lab equipment, can be used to reduce electricity consumption. sharing his

electricity, fuel oil, propane, and district heating. what is energy use intensity (eui)? energy star buildings learn the difference between source and site energy. some property types are more energy intensive than others. generally, a low eui signifies good energy performance. however, certain property types will always use more energy than others. for example, an elementary school uses relatively little energy compared to a hospital.

of a system and the quality of your products. often the screen is one of the least expensive pieces of your system, while having an outsized impact on your profits. many applications utilize mechanical screening processes for the reasons mentioned above. see full list on aeiscreens mechanical screening is the probability of a particle of a given size passing through an opening of a given size. as the size of the particle approaches the size of the opening, the probability of passing that particle through the screen decreases. conversely, as the particle size decreases and the screen opening increases, the probability of passing the particle increases. each opening in a screen presents an additional chance for a given particle to pass through. the more openings a particle is presented with, the higher the probability of passing that particle. in realworld screening, this is witnessed through the particle distribution of the fines product and the coarse product. 100% efficiency does not happen in practice. screening efficiency is defined as the ratio of the material that should pass through a given opening and the material that actually passed through that opening. in practice, the product distributions will be shaped like a curve. fine particles pass the quick see full list on aeiscreens by increasing the screen length, you can increase screen efficiency by providing a longer time and probability for near size material to pass through the screen media. every application and material presents a unique challenge for a particular screen. even

to membrane filtration is used to remove particles that are too fine for ordinary filtration techniques such as proteins, bacteria, viruses and dissolved salts from liquids. it can also be used for concentrating, fractionating, purifying and regenerating liquids, partially or totally replacing traditional methods of separation by evaporation and centrifugation. figure 41 separation capacity of various membrane filtration technologies in the agroprocessing industry, we are likely to encounter four types of membrane technologies, depending on the application: microfiltration, ultrafiltration, nanofiltration and reverse osmosis (ro). these methods are differentiated by their separation capacity, which is a function of the membrane pore size, and the molecular mass of the particles we want to remove. although these technologies have already proven their worth in several industrial applications, there remains ample room for growth. in many cases, they can partially or totally replace see

technologies (mvr), which are addressed in section 4.3. heat pumps are compression based refrigerating apparatuses designed to transfer heat for heating rather than cooling purposes. they capture thermal energy at relatively low temperatures (c source), warm it and transfer it to a heat sink. in the evaporator, the low temperature heat source transfers energy to the refrigerant, which then vaporizes. the compressor temperature and pressure increase while the refrigerant remains vaporized. in the condenser, the refrigerant transfers the accumulated energy to the heat sink. at the condenser outlet, an expansion valve reduces the pressure of the refrigerant. the lowpressure liquid then returns to the evaporator to restart the cycle. applications: meat, dairy and beverage industries that require heating and see full list on nrcan.gc mvr is a technology belonging to the family of openloop heat pump systems that are especially well suited to evaporation processes. mvr allows the latent heat contained in steam, which is often lost in traditional processes, to be recovered. steam generated by evaporation is recovered by a compressor, which increases pressure and temperature to several degrees above the liquids boiling point. after this steam reaches a high temperature and pressure, it provides a heat source for evaporation as it releases its latent heat. reclaiming the energy contained in the steam makes significant energy savings possible. in fact, only 30 kwh are required to evaporate 1 m3of steam, compared to 800 kwh with traditional evaporation. applications: concentrating milk, brewing beer (wort kettle), concentrating effluents, distillation, separation. potential: in addition to reducing energy consumption, mvr can also significantly cut refrigeration needs (water, cooling tower) and, in some cases, o see full list on nrcan.gc traditional systems for generating electricity have an average efficiency of 35 to 40 percent (as high as 55 percent for combinedcycle systems), releasing 60 to 65 percent of the energy content of their fuel into the environment. cogeneration reclaims this heat loss and applies it to heating or cooling needs. heating includes the production of steam and hot water. cooling requires the use of absorption chillers that transform heat into c. thus, by simultaneously generating electricity and heat, cogeneration units have a higher overall efficiency that may reach 90 percent. this represents savings on fuel as high as 40 percent compared to electricity and heat production using thermal powerplants and steam boilers. figure 42 generation of heat and electricity with cogeneration figure 43 distribution of industrial cogeneration facilities in canada because electricity can be transmitted across great distances more easily than heat, industrial cogeneration facilities are general see full list on nrcan.gc the anaerobic process is one of the most promising avenues for treating industrial effluents and waste with a substantial load of organic matter. in the absence of air and oxygen, some bacteria transform organic residues from vegetable, animal and chemical sources into biogas (consisting of methane and co2), which can be used as fuel to replace natural gas and fuel oil. depending on the specifics, the process is called anaerobic treatment, digestion or fermentation. these designations are equivalent and we have opted for the term anaerobic treatment (at) in this guide. a wide variety of organic compounds can be treated anaerobically: carbohydrates (starch, sugar, cellulosic materials), fats and oils, and proteins. at is well known in europe and asia, where it is estimated that hundreds of such industrial systems are in operation, but in north america the process is still poorly represented, with a mere 12 percent of the worlds facilities. figure 44 breakdown of industrial anaero see full list on nrcan.gc traditional modes of heating and cooking food in hot air ovens or by contact with heated surfaces are now complemented by new highefficiency modes based on electrotechnologies. these techniques include infrared, high frequency and microwave radiation, as well as ohmic and induction heating. the principles behind these different modes of heat transfer vary considerably from one to another, but they are all designed to heat the product rapidly and efficiently, while meeting taste and nutritional criteria. the principal benefits of these technologies are demonstrated by the following examples: 1. high energy yields (up to 95 percent) 2. direct heating with no intervening fluid 3. quick response time for startup, stop and adjustment 4. precise temperature adjustments 5. oilfree cooking processes 6. minimal loss of product mass see full list on nrcan.gc pasteurization of a food product is the process of eliminating or deactivating microorganisms that may affect quality. depending on the product and the technique used, the classic process consists of heating the product to a temperature of between 60°c for beer and 72°c for milk, or even higher, before or after the product is conditioned in a plate cooler or a tunnel pasteuriser. however, hot process pasteurization has the disadvantage of being a major consumer of energy and it may affect the organoleptic properties (principally taste) and nutritional value of the product. to avoid these problems, new techniques in c process treatment developed in recent s all share the feature of rapidly reducing the microbial community at a moderate temperature. these techniques have a wide range of applications in the agroprocessing industry, from product pasteurization to disinfection. over time, their deployment is expected to gain wide acceptance in canada. more advanced techniques, suc see full list on nrcan.gc homogenization consists of breaking globules suspended in a liquid into smaller particulates to create a mixture that is more homogeneous and stable. the operation takes place in a homogenizer in which the liquid is forced through openings or valves under pressure. in the dairy industry, the purpose of homogenization is to break globules of milk fat into smaller particles to distribute them evenly throughout the milk. this process stabilizes the product and, in particular, keeps the fatty matter from rising to the surface as cream. it also confers physical and organoleptic properties that make the product attractive on the fluid and industrial milk markets. in recent s, manufacturers have developed new generations of highefficiency valves that work at lower pressures, reducing equipment electricity consumption 15 to 30 percent while maintaining the same quality of homogenization. application: homogenizing milk. potential: the
