Only farmers can deliver this.
Only farmers can deliver the following. According to World Bank figures, the global production of urban waste is above 2 billion tonnes and rising. My own experience of composting urban wastes suggests that, technically (if the regulators could come to terms with this) maybe 25% of that could be composted and put to farm land, and possibly more if put to forestry land. If the compost contained only 2% of each of N, P and K, then that would be 10 million tonnes of each. One tonne of N nutrient, made in a modern USA factory, takes 21,000 kWh to make and deliver. So, or the N alone, that would save the use of 210,000,000 kWh of electrical power generation, most of which comes from burning coal and oil. Bearing in mind most N production in the world is several times less efficient than in the USA, and that the rest of the figures err on the side of caution, then recycling urban waste by composting to land would save probably around 1 trillion KWh pa and the associated Carbon dioxide production. As a rough guide, that would save 350,000,000 tonnes of Carbon dioxide being pumped into out atmosphere, every year.
There is a bonus, crops grown on high organic Carbon soils need less irrigation and less crop protection sprays. Cereal crop lodge (fall flat) less. Crops yield a little more. What we need is active, controlled enabling, not ever-increasing suppression and indifference form government.

It is not impossible to turn global warming upside down.
The New Scientist this week comments on the Intergovernmental Panel on Climate Change (IPCC) report that we have 12 years to save the planet. Interestingly, while pointing out that the evidence is overwhelming that the rise in global warming is human-made and really dangerous and already producing problems, they also argue that the evidence is that we can do something about it.
What this blog is sometimes about is that composting urban waste globally could make a real contribution to limiting and even reversing by locking up Carbon in organic matter and by reducing and eliminating the manufacture of Nitrogen fertilisers (which, according to UN-sponsored research takes 21,000 kWh to make one tonne of N nutrient – and that is in a modern and efficient USA factory).

We know that burning aviation fuel advances global warming by producing GHG (Green House Gas), BUT, it also delivers what is called “global dimming” because the ice crystals which allow us to see jet contrails also reflect sun radiation back into space. Complexity yields uncertainty.
The global weather system is complex and how it will change with respect to the global warming that we all (except, apparently, Mr Trump) know is happening is difficult to predict in detail and fast enough. One of the problems with that is that by the time we are sure of something, it may be too late to do much about it. The evidence so far does not suggest that climate change causes hurricanes. However, it’s becoming more and more clear that a warming climate leads to more devastating hurricanes.
As far as UK farming is concerned, the implication is that winds generally will get stronger and storm winds will do more damage to crops. Wind breaks and stronger cereal straw are still likely to be part of the defence strategy. Wind turbines may be a better investment, too.

The soil is much as the cow’s rumen. It is not the cow that digests the food, it is the rumen micro-organisms. then the micro-organisms feed the cow.

Well done Devizes primary schools! Children being constructive about recycling plastic waste.
Devizes primary schools put these models made from plastic waste on a roundabout in the center f town,
These constructions made from waste plastic have been on display on a roundabout in the center of Devizes in Wiltshire for several weeks. They have been seen by thousands. Well done children, teachers and the local authority..

Putting “waste” into an AD plant to make “renewable ” energy can make sense, despite the energy cost of the plant. However, growing crops to feed the plant is both insane and immoral.
The energy cost of the steel, plastics used in the construction of an AD plant, plus the energy involved in construction, can sometime make environmental sense and make a small contribution to energy security, However, it is as well to remember that 1 tonne of Nitrogen fertiliser nutrient, made in a modern and efficient USA fertiliser factory, according to UN-sponsored research, typically takes 21,000 (yes, twenty one thousand!) kWh to produce and deliver. N fertiliser produced in eastern block countries may use as much as 20 tomes more power. So, using fertilisers, to grow crops, to harvest using diesel to cut and transport to an AD plant, to digest to produce methane, to burn in an engine to drive a generator to produce even less electricity is insanity based on ignorance. What is more, that land could be used to produce food and we need food security and so do 100,000,000 people in central Africa which the UN reports are on the edge of starvation death. That is immorality on a global scale sanctioned by ignorant government. in Brussels and Whitehall.
(There is a chapter on renewables in general and AD in particular in “Survival”.)
