Two things that are interesting about the examples discussed are:
1) They mainly reduce the factories impact on the environment by saving water, energy or reducing emissions which are often product, raw material or byproduct. So the fixed production costs are very often reduced at the same time as the environment benefits.
2) They are seldom complicated or technologically groundbreaking and are often common sense.
A few examples are
Campbell Soup reduced energy consumption by 4,85 and water by 13,45% by installing utility meters, introducing recycling, installing energy saving light bulbs and introducing low flow water nozzles.
Craft Foods reduced its energy cost by 60% for a new cold store by installing it underground in a limestone formation.
General Mills produces 90% of the steam it uses in its milling and preparation plant for Breakfast cereal production production, by burning the bran produced in the plant.
Musco Ollives uses 15 tons of olive pressing waste a day to produce enough steam from waste water to produce power for production.
Kroger distributes 30 million meals a year from food that, although safe and wholesome, is destined for landfill for commercial reasons.
SAB Ltd, is funding water saving projects to compensate for its potential water consumption of 14 billion litres a year in South Africa. WWF (World Wildlife Fund) is facilitating the “water neutrality process” with a South African Government Project to ensure that this is not just a multinational greenwashing!
SAB Ltd is the South African subsidiary of SABMiller which is the second largest brewery in the world .
“The concept of water neutrality, based on its carbon equivalent, has been used loosely over the past years; however, until now no-one has been able to quantitatively justify these claims. We believe that our scheme is the first in the world that allows participants to truly claim to be water neutral.”
Participants will replenish water supplies, by investing in projects that quantitatively supplement water supplies equal to their water usage.
Note: Water neutrality has taken on a form in certain areas that is significantly different to the process introduced here by WWF.
This report finds that 28% of the mass and 32% of the value of all food bought in the UK is wasted.
While this is important to the UK food chain it also effects the rest of the world as the food chains runs back to the farm, maybe in Africa where 30% too much energy, water and labour have been used satisfying the UK food market!
