Co 2

I know this is going back to a comment quite early on in this discussion, but thought a response might be appreciated.  

The theoretical yield of CO2 is about 747 kilograms per 1000 litres of alcohol produced.

So, putting that into something relating to beer, 747 kg CO2 would be produced from fermenting 20,000 litres of 5% beer.

However, CO2 can only be collected from enclosed vessels – many microbrewers in particular are still using open vessels.

The cost of CO2 purification plant, and operating costs mean that very large volumes of CO2 need to be produced to make collection economic.

 Although theoretically 747 kg could be collected, only 500 kg CO2 can actually be collected.  Losses are due to some remaining in solution at the end of fermentation, a fair bit being so impure due to entrained air (oxygen & nitrogen mainly) that it is not economic to collect.

Finally, the collected CO2 is used to carbonate beer before packaging (exception cask beer – about 7% of total beer sales if I remember correctly), and to remove air (critical gas is oxygen) from tanks and final package (kegs, cans, bottles).  Unfortunately, that means that even large breweries with CO2 collection systems have to buy in additional CO2.  The only slight consolation is that it is “green” CO2 from plant material, rather than from petrochemicals.

Re distillers, since they don't use CO2, as far as I know, none of them have a CO2 collection system.  Why should they when it is not their core business and volumes are small compared to some of the breweries?  

This Country gave the World Technology, Language, Science discoveries 

I think that being very insulting to every other old world country who developed all those things long before this country. Each country has its own language, with Latin, Greek and Arabic being at the root of our own modern language. China and Arabia used technology and science long before it was introduced into this country.

Yes, but apart from the sanitation, the medicine, education, wine, public order, irrigation, roads, a fresh water system, and public health, what have the Romans ever done for us?”

Showed us how to take Penalties!

Insulting?, no you have taken my post out of context. I accept it would have been insulting if that was my intention, it was not. I posted from the position of someone who is extremely proud of this country & it’s leaps forward over the centuries, I wondered at the intelligence, creativity & ingenuity of our forefathers.

penicillin-Alexander Fleming, lives saved approximately 200 million & counting.

industrial revolution started in Britain & was exported around the world.

English(Language) the most widely spoken international language around the world used by over 1.1billion people. 

im not one for trashing our country whilst talking up others, I believe all countries stand with positives & negatives. We have fought just to stand still recently, the balance has now tipped & we’re beginning to go backwards it’s immensely saddening to me, our own people will suffer.

PS-English is a modern language in comparison to others. English has traces of most other countries language in its make up. I usually use our Language against the xenophobes who believe this Country is no place for ‘foreigners’, we are a mix of ‘foreigners’ I’m part Italian/Scots & Irish🤷🏻‍♂️

We quite often see two or three DHL vans In. our area at the same time  ,a driver told us  they load at different bays at the warehouse, so parcels for the same road or address could well be on separate vehicles  you can see with the tracking your parcel app where your parcels are as each has its own code

Wouldn’t you think they would get their act together

Sorted our neighbors today just in case no CO2 and no turkeys. All had a big Rainbow trout which I caught and will be a substitute for Xmas  if necessary. Just frozen for freshness.

If they both had the same tracking number yes
