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. 


The Psychology of EBikes

The Psychology of EBikes


For the cyclist who is less fit, aging or wants to haul heavy loads and  EBike is an obvious choice. It will do some of the work for you whilst enabling you to do what needs to be done. Alternatively you may be opting for an EBike becuase you wish to use you car less. Each situation produces a certain set of considerations in terms of  how we may think about the Ebike.

Do you get the same buzz from riding an EBike that you do, when riding a normal bicycle?
Is an EBike better for the Environment?

The answers to these questions and therefore how you feel about the switch will depend on whether you are considering an Ebike as an alternative to a car or or bicycle  . . . or perhaps some other form of transport.

As an alternative to a Bicycle


Sense of Achievement

When returning from a 10, 15 , 20 mile ride on a normal bike you think:

"Wow I got all that way under my own steam. . . well done me"

When you do the same (or further on an EBike) how much have you achieved? In terms of effort certainly less, and therefore should you take less satisfaction from the journey?

Chill Out Time

Riding a normal bike is a very organic experience, and it is quiet too. This is relaxing.  Perhaps you will not feel the same after listening to the whine of an electric motor for 1/2 an hour.

An EBike ride is still a lot more  relaxing and invigorating than driving car, but isn't an EBike just a slow motor bike?

Environmental

I can cycle 15 miles on a pizza. However the fuel for my EBike is rather more complicated. I need to charge it up. . .where does this electricity come from. In nearly all countries around the world, some of the electricity will be provided by fossil fuels, the burning of which contribute to climate change. In france for example charging my bike will create 5 times less CO2 than in the UK.

A green electricity tariff will help lower these impacts and promote new renewable energy infrastructure.

There is also the impact of manufacturing the bike. There are few electrical components in a normal bike, whilst there are printed circuit boards, copper wire, and solder contained used in the manufacture of an EBike.

As an alternative to a Car


Sense of Achievement

You get a higher sense of achievement from making a journey on an EBike than you do than using a car. After all being out in the elements on a bike (Ebike or normal bike) is still more of an adventure than if you went in your metal box on wheels (car).

Chill Out Time

This depends greatly on your attitude, if you choose to follow a direct busy route, travelling mixed with speeding cars, then you will be worse off then if you drive.

The key here is to accept the fact that an EBike takes a long time to get anywhere, and plan to take an indirect quiet route on minor roads. This way you will get some chill out time.

Environmental

Unless you car is electric, then this is where an EBike will win hands down. A bike creates a lot less environmental impact in its manufacture then a car, and charging uses between 20% and 100% renewable energy depending on your source.

For a 1 mile trip your carbon footprint for fuel would be:

ebike_carbon_footprint
Carbon Footprint - Car vs Bike vs Ebike
However, how you fuel your body make a big difference. For example a Vegan driving a small efficient car will produce less CO2 per mile, than a meat eating cyclist. 

Conclusions

The benefits from moving away from a car to an EBike are plain to see. You should feel awesome. 

Whilst you get less exercise, and create slightly more environmental impact riding an ebike as opposed to a bicycle, don'y worry too much the differences are marginal.

Staying chilled out whichever route you are on depends on your attitude.
