Thus the marginal efficiency of capital is the percentage of profit expected from a given investment on a capital asset. Keynes relates the prospective yield of a capital asset to its supply price and defines MEC "as being equal to that rate of discount which would make the present value of the series of annuities given by the returns expected from the capital asset during its life equal to hospitals), and, to a lesser extent, economic infrastructure (e.g., roads and electricity). However, the economic and social impact of public investment critically depends on its efficiency. Comparing the value of public capital (input) and measures of infrastructure

Capacity Utilization Rate (Definition, Formula)

The higher the utilization rate, the higher would be the operational efficiency of the company. Even capacity utilization has a great effect on economic policies. When policymakers make economic policies, they look at capacity utilization to figure out how to

Efficiency of labour is also dependent on the social, political and economic conditions of the country. Important factors are: (i) Climatic Conditions: The climate of a place also determines the efficiency of labour in a country. Workers who live and work under hot

Triple bottom line and sustainable performance

The purpose of this paper is to propose a minimum set of indicators to be measured by industrial companies to represent the triple bottom line (TBL) approach.,The research is both descriptive and quantitative. Three hypotheses establish associations among the

Optimization of the activated sludge process, and return activated sludge flow rate, requires careful management of three critical parameters. Over the years, wastewater professionals have based their control decisions on measurements from batch tests supplied to various samples or from infrequent laboratory analysis. Those are measurements done on composite samples for compliance purposes

Calculating manufacturing efficiency helps companies determine how well they are spending their resources, like labor and supplies. Improving their manufacturing efficiency by hiring employees or changing production processes, can help businesses become more

The environmental consequences of plastic solid waste are visible in the ever-increasing levels of global plastic pollution both on land and in the oceans. But although there are important economic and environmental incentives for plastics recycling, end-of-life treatment options for plastic solid waste are in practice quite limited. Presorting of plastics before recycling is costly and time

California's Department of Resources Recycling and Recovery's mission is to help state residents achieve the highest waste reduction, recycling and reuse goals in the U.S. The following is an excerpt from a cost benefit analysis performed in 1997 to compare the costs of Cardiovascular Group's (CVG) solid waste reduction program to its economic benefits.

The conversion efficiency of a photovoltaic (PV) cell, or solar cell, is the percentage of the solar energy shining on a PV device that is converted into usable electricity. Improving this conversion efficiency is a key goal of research and helps make PV technologies cost-competitive with conventional sources of

reasons of technical feasibility, economic viability and environmental protection. This must be justified in line with the provisions laid out in Article 4(2) of the Waste Framework 9 Article 2 (6) of Commission Decision 2011/753/EU establishing rules and

PPF and Economic Efficiency Production Possibilities A production possibility frontier is used to illustrate the concepts of opportunity cost, trade-offs and also show the effects of economic growth. Points within the curve show when a country's resources are not

Sustainable Management of Construction and Demolition

EPA's 2016 Recycling Economic Information (REI) Report showed that in 2007 the recycling of CD materials created 230,000 jobs. Reduce overall building project expenses through avoided purchase/disposal costs, and the donation of recovered materials to qualified 501(c)(3) charities, which provides a tax benefit.

Calculation For Part Count Per hour Cycle time (seconds): Mold cavitation: Parts per hour: Production Time Use this calculator to find the time required to complete a production run given the part quantity, cycle time number of cavities in the injection mold.

Economic size attracts countries to trade, and economic distance makes trade harder. Economic distance is increased by barriers to trade, and cultural, political and linguistic differences. One advantage of gravity theory is that it can help economists predict the likely effect of changes in government policy on trade patterns, including decisions regarding joining (or leaving) trading blocs .

2020/8/23The levelized cost of energy (LCOE) calculator provides a simple calculator for both utility-scale and distributed generation (DG) renewable energy technologies that compares the combination of capital costs, operations and maintenance (OM), performance, and fuel costs. Note that this does not

The chapter focuses on the economic feasibility of waste tyre treatment through pyrolysis in Gauteng. The authors also evaluate the role of existing policy instruments, transition towards a low-carbon economy as well as optimal energy strategies influencing and promoting efforts towards integrated waste tyre management in South Africa.
