Gove's Green Post Brexit UK - Beware I Say!

Gove's Green Post Brexit UK - Beware I Say!

The Environmental Secretary Micheal Gove has promised a  Green Post Brexit UK but beware I say! Things are happening under his watch that are not good, I aim to keep a list of things here:

Post Brexit Green Watchdog

At the moment if the UK step out of line with regards to the environment we get our wrists slapped by the EU. A recent example is the EU fining the UK for its air quality failures.

Post Brexit this will not happen, so we need a EU level equivalent independent body to make sure the government follows it own rules.

The house of lords have voted that details of this watchdog need to published, but the government has delayed publishing it until after the 3rd reading of the EU withdraw bill. This deferral means that there will less time to check proposed measures, and the danger it will become lost in the scrabble in to the run up to our ridiculous exit from the EU.

If you have any other ideas for inclusions please leave a comment and I will type them up.

Weak UK Plastics Targets - Outshone by EU Equivalent

Weak UK Plastics Targets - Outshone by EU Equivalent?

Whilst the the UK government published its intend to phase out "avoidable"  plastic wastes within 25 years. This seeks to target single use plastics, which is laudable but as with most Conservative environmental policy, it is wooly and ill defined.

It is a pi$$ poor effort from Theresa May's government. Our reliance of cheap single use plastics is causing measurable suffering across the planet:

  • Whales Tangled in Ropes
  • Micro Plastics Contaminating Food Stocks (Even Sea Salt)
  • Birds feeding their young with plastics items (That are mistaken for fish)
  • Mounds of plastic film at waste dumps across developing countries.
  • UK Plastics exported to Africa where child labour is used for processing.
So despite all of this a 25 year target is deemed as acceptable. When it plainly is not. One start to believe that the Tories are afraid to mention anything that is not directly linked to making money. 

So step up the EU, the worlds number 1 club for enlightened nations. Who have pledged a far more stringent target of 65% re-use in 12 years, with interim targets set of 60% in just 7 years. So unlike the spineless targetless waffle proffered by the Tories, we have something to aim for at least.

Although we may soon have no say in how this EU Circular Economy is setup, we will almost certainly have abide by its rules. Unless we abandon the EU as a trading partner. The UK currently recycles 45% of waste.

To be clear the EU targets apply to all wastes, not just plastics, which are subject to further strategies based on recyclability, biodegradability and the presence of hazardous substances. 

So in summary the Uk will have to recycle 15% of all wastes by 2025. We will also have to change the nature of our plastics, to meet EU regulations. 

Theresa May's announcement really is just a reworded EU strategy that her government will have to follow anyway.

Ibuprofen - Damages Male Fertility - Endocrine Disruptor

Ibuprofen - Damages Fertility - Endocrine Disruptor

A new study published on the 8th of October in the  Proceedings of the National Academy of Sciences of the USA presents evidence that Ibuprofen (a widely used anti-inflammatory) shows the “the broadest endocrine-disrupting properties identified so far in men”, with a “striking dual effect” on two types of testicular cells. This may be good news for the environment, population growth has risen over 5 births per second in 2017. In some respects it is s shame this has been discovered. . . .

Endocrine disruptors are chemicals that may interfere with the body’s endocrine system and produce adverse developmental, reproductive, neurological, and immune effects in both humans and wildlife.

Ibuprofen disrupts the balance of hormones within the body, with the normal production of testosterone being altered, and sustained by increased activity of the pituitary gland which is not a good thing. 

This over activity of the pituitary gland was diagnosed via the measurement of the hormone luteinising, which was shown to be elevated in the clinical trail participants and in vitro cellular study. 

This imbalance is termed compensated hypogonadism. Hypogonadism means diminished functional activity of the gonads—the testes in males or the ovaries in females—that may result in diminished sex hormone biosynthesis.

Ibuprofen has also been observed to have other negative effects such as slowing healing. These findings are unsurprising as the bodies response to healing or cell production is often inflammatory in nature, and as an anti inflammatory, Ibuprofen is very likley to put a spanner in the works of many bodily processes, that we do not fully comprehend. 

In the UK 1.4 billion Ibuprofen Pills are taken each year.

Bucket Crusher and Mobile Crusher Noise / Sound Levels

Bucket Crusher and Mobile Crusher Noise  / Sound Levels

There are a great many sites titled "crusher sound levels" or "bucket crusher noise" which do not publish figures of decibel levels.

I have come across this HSE document (governmental body) which one would hope is reliable. The document is "Control of Noise in Quarries".

The document lists various sound / noise level for static / fixed and mobile crushers in decibels / dBA / db. For a bucket crusher I used figures listed for a mobile crusher platform, as they are likley to be closer match in terms of size.

You will note the table also includes way to reduce noise for the operator. However, the document is not aim at environmental noise reduction.

Text Version of Above Data  

Primary crusher cabin  - 108  dB(A)
Compressor -  100  dB(A)
Drill  -105  dB(A)
Secondary crusher -107  dB(A)
Secondary crusher - 91   dB(A)
Metal transfer chute - 119   dB(A)
Metal - 119  dB(A)
Screen building - 88  dB(A)
Mobile crusher platform -103   dB(A)
Mobile crusher cabin - 93 dB(A)
Hand drill  - 110  dB(A)
Mobile crusher - 92   dB(A)

Set-Up Windows 7 Pro Host for Multi Monitor RDP / MSTSC

Set-Up Windows 7 Pro Host for Multi Monitor RDP / MSTSC

This was connecting FROM a windows XP SP3 Laptop TO a Windows 7 Pro Desktop.

I was using an additional monitor n the lap top.

The main break through is using RDP Wrap, and piece of software that does something to allow use of multi monitor support on WIndows 7 Pro.

It Works!

Just download this and intall this on client computer.

RDPInst.exe and then Install.bat.

Then make sure you have rdp 7 or above on your XP machine, and check the box that says "use all my monitors in the display tab of the RDP program.

Microsoft have removed the patch for upgrading XP, so here is is here.

Carbon Footprint of Cycling per Mile

Carbon Footprint of Cycling per Mile - Intro

Many basic graphs that compare cycling with other modes of transport rate cycling as "zero" impact.

This is fine as like walking cycling is one of the lowest carbon forms of transport available. However, when we consider the fuel that the cyclist uses i.e. the food they eat in order to gain the calories burnt in cycling does this change anything?

Carbon Footprint of Cycling per Mile - grams of CO2 per mile for a Car

Our benchmark for our CO2 per mile will be that described in "The Ecologist" of 168g/CO2/mile, for a car. 

Carbon Footprint of Cycling per Mile - grams of CO2 per mile for a Bicycle

Now consider the calories burnt cycling 1 mile on a Bicycle, this varies base don the speed and the weight of the rider, but a conservative figure might be 50 calories per mile. How does the cyclist get those calories . . . ?

Eating meat, is carbon intensive. . . a meat rich diet creates over double the CO2 footprint of a vegan diet. 

So if we we were to cycle 1 mile on a vegan diet, vegetarian or "all in" dirt we would create different emissions. 

gCO2 per mile by Diet 

So if we then apply our 50 calorie per mile number to the CO2 per calorie we get:

CO2 per mile by diet - Bicycle

Remember a mile in a car creates 168 gCO2, from burning fossil fuels.

Carbon Footprint of Cycling per Mile - Making a Comparison

Now the average person burns 68 calories per hour whilst sitting. On a single carriage way the driver of a car will burn 1.4 calories per mile. So we can add this CO2 burden to that produced by the fuel. Sp if we add in the metabolic co2 impacts we get. 

CO2 per mile by diet - Car

Carbon Footprint of Cycling per Mile - Conclusion

Cycling would appear to only save carbon if you eat a low meat diet. Please note this post is restricted to operational impacts only, and does not consider manufacturing impacts or infrastructure impacts.
