calculation of economic efficiency of limestone recycling

Evaluation of Agricultural Limestone - British Columbia

This rating suggests that limestone A would be about 10% less efficient than limestone B. This calculation implies that roughly 10% more of limestone A would be required to achieve the same change in soil pH as would be obtained with a given quantity of limestone B. 2. Neutralizing Capacity . Another factor which influences the efficiency of a limestone is its neutralizing capacity. This is ...

Frequently Asked Questions: Benefits of Recycling Land ...

A: In a broad sense, recycling is part of an ethic of resource efficiency – of using products to their fullest potential. When a recycled material, rather than a raw material, is used to make a new product, natural resources and energy are conserved. This is because recycled materials have already been refined and processed once; manufacturing the second time is much cleaner and less energy ...

The Economics of Waste and Waste policy - GOV.UK

Economic efficiency – in the waste context – is attained when the amount of waste generated (and managed at each level of the hierarchy) is optimal, i.e. the costs of reducing waste by one unit is equal to the economic and environmental benefits of having one less unit of waste. There are costs and benefits associated with reducing waste. For example, reducing waste through making ...
