Take-back initiatives

The organizations common objective, in short, is promoting national-level solutions for hazardous waste management [18]. One recent initiative has been e-Stewards, a system for auditing and certifying recyclers and take-back programs so that conscientious consumers know which ones meet high standards [19]. 

Now suppose we have a small coupling between the pendulum and the rotator (i.e., 0 < p < 1). Suppose we take the initial condition so that we set the pendulum at a state near its unstable fixed point (0,0), and the action variable of the rotator is I2 - if 1 — ( Then, as time proceeds, the pendulum repeats swinging. At the same time, because of the coupling p, the action variable I2 changes its value. When the pendulum comes back to the neighborhood of... 

Measures related to sustainable risk management would include accrued environmental liabilities, fines, warnings and penalties, as well as product take-back programs whether in compliance with or in addition to regulatory initiatives. 

Chapter 17, the most hands-on chapter in the book, focuses on only one planet (and I m using that word loosely) the Moon. Its monthly swing through all of its phases and all 12 signs brings days when the cosmos is with you — and days when it s decidedly not. In this chapter, I tell you how the position of the Moon can help you decide when to take the initiative, when to hang back, when to start projects, when to wait, and more. 

Lamarckian is modeled on Lamarck s theory of inheritance of acquired characteristics, in much the same way that the basic GA is modeled on Darwinian evolution. The term usually means that the evaluation function takes the initial parameters decoded from the chromosome and carries out a local function minimization. The parameter values at the local minimum are recoded into the chromosome and passed back to the main GA routine along with the value of the fitness function at that point. The environment has caused a direct and (locally) beneficial change in the individual s genes that can be passed on to its offspring. 

Each teacher intern attends a one day orientation meeting before beginning summer work. At this meeting, initial plans are made regarding the development of classroom materials which each teacher will take back to the classroom for use after the internship has been completed. (The 1988 interns were required to have their industry and school supervisors with them at this orientation. This has been eliminated due to the difficulty of melding schedules.) ... 

The incorporation of take-back policies should be an initiative shared among a diversity of entities including the original equipment manufacturers (OEMs), government, recovery companies, distributors, and even customers. Beyond the policy framework, new paradigms must be established in order to promote sustainable products and closed material loops at product end-of-use. In this sense, concepts such as Product Service Systems (PSS) and Producer RespraisibU-ity Organization (PRO) could support this purpose. 

Sony Electronics Inc., in cooperation with the State of Minnesota and Waste Management, Inc., initiated a five-year program in 2000 to take back all Sony electronic products in Minnesota at no cost to consumers. It operates through drop-off sites, which also accept other brands of electronics for a small fee. Over 8000 pounds of electronics were collected through this program in 2002. ... 

When a solid surface is exposed to a gas, the molecules of the gas strike the surface of the solid when some of these striking molecules stick to the solid surface and become adsorbed, while some others rebound back. Initially the rate of adsorption is large because the whole surface is bare, but the rate of adsorption continues to decrease as more and more of the solid surface becomes covered by the adsorbate molecules. However, the rate of desorption, which is the rate at which the adsorbed molecules rebound from the surface, increases because desorption takes place from the covered surface. With the passage of time, the rate of adsorption continues to decrease, while the rate of desorption continues to increase, until an equilibrium is reached, where the rate of adsorption is equal to the rate of desorption. At this point the solid is in adsorption equilibrium with the gas. It is a dynamic equihbrium... 

In early 1990s, Xerox launched a new initiative to take back used copiers as a source of materials for new machines. Customers like the programme because they no longer worry about machine disposal. 

In the early 1990s, legislation was proposed in the US, but no regulatory action was taken. The movement toward lead-free electronics emerged into concrete legislation in Europe on June 13, 2000 when the European Commission adopted two proposals A Directive on Waste of Electrical and Electronic Equipment (WEEE), and a Directive on the Restriction of Hazardous Substances (ROHS). The WEEE requires Member States to set up take-back centers for end-of-life recovery at no cost to the consumer. The initial WEEE included the ROHS requirements and... 

In addition to the benefits derived from take-back programs discussed in the preceding sections, yet another key benefit is the significantly reduced volume of waste disposed in landfills or by incineration. However, an integral part of take-back systems is the removal of harmful and toxic materials prior to disposal. This chapter discusses legislation and other initiatives to achieve these objectives at various geographies worldwide. 

Capture opening(s) locations should be chosen to take advantage of the initial release direction of the contaminant. This leads to locating exhaust openings in the back, floor, ceiling (e.g., for heat-emitting processes), or side walls of the booth. In many cases it is useful to combine exhaust openings in different sides of the booth. 

Most chemical reactions are reversible, at least to some extent. We will use Pt(AB) = 0.05 again, and start with all of the cells in the A state. To add the back reaction B A to the forward reaction A B, we need to add a transition probability Pt(BA) for the B A transition. We will initially take Pt(BA) = 0.08 and observe the results, again after 500 iterations. How many A ingredients remain after 500 iterations How many remained in Study 2.3a ...
