Wash your Trash! Is recycling working?

By Andy May

The recycling movement started in the 1970s and it has been very popular in Western countries. Participation varies with location, but in our small community of The Woodlands, Texas, over 90% participate in our curbside recycling program. However, the value of recycled materials has fallen dramatically in recent years because far too much unrecyclable material is put in the bins by the public and much of what is recyclable is contaminated with water, food, or other contaminates that make the “good” stuff unusable. Waste disposal companies often charge “contamination fees.” In addition to the contamination problem, the value of recyclables is going down and cost to process them into a usable form is going up. Processing, that is cleaning and sorting a load of recyclable material, has gone from earning a community $25/ton to costing the community $70/ton or more in many areas. In 2015 recycling was a revenue generator for Houston and other cities in the area. Bellaire, for example, generated $12,000 in 2015 from curbside recycling, but in 2017, they lost over $80,000 for the same program.

Paper and metals, especially aluminum, are the easiest and most valuable materials to recycle, but if they are stained with food or left-over beer or soda, they are rejected and wind up in the landfill anyway. Wet paper, even wet with water, often cannot be recycled. Paper stained with food cannot be recycled, this includes pizza boxes and juice boxes. For more details about what can be recycled and how the materials should be washed and prepared for recycling, see here. Be aware that recycling rules vary from place-to-place and that those I mention here may be different from those in your area. Follow your local rules. This lack of uniformity is confusing.

Glass is still recycled in some areas, but most reject all glass currently because non-recyclable glass items and dirty bottles are too commonly placed in the bins. Basically, any clean glass bottle or jar, intact, with a neck and lid can be recycled. But it must be clean and without any food contamination or it will be rejected, and the contents may contaminate other perfectly recyclable materials in the bin. This is also true of plastic bottles, tubs and jars, they must be very clean and have caps or lids. Only rigid plastic containers can be recycled, no film, no plastic bags and no scrap plastic. Yogurt, ice cream containers, etc. cannot be recycled, in fact all plastic covered paper and cardboard cannot be recycled. Milk bottles can be recycled, but they must be clean and still have the cap on them.

Some contamination in recycling bins is to be expected, but recycling companies and cities are severely penalized if more than 25% of the recycled materials are contaminated with food waste, water or other contaminants. This raises the cost of recycling dramatically and often causes communities to abandon recycling altogether.

China used to buy up to 70% of the world’s waste plastic, but they stopped taking it and this has caused the cost of recycling to go up dramatically. China stopped taking our recyclables because they were contaminated with “highly polluting” materials that were fouling their land, rivers and coasts. Even Vietnam, Malaysia, and some countries in Africa are limiting their imports of recyclables. They would welcome cleaner recyclables, but the contaminated portion of the loads wind up in local rivers and in the ocean, where they are not only unsightly, but they affect the fish and can causes disease.

So, what do we do with the 267 million U.S. tons of trash we generate each year? In 2017, the EPA estimates it was ultimately disposed of as shown in Figure 1. Notice that only 25% was recycled, this is after the contaminated garbage and unrecyclable materials were removed. Dry clean paper was 66% of the total and metals, like clean aluminum cans were 12%. Notice that plastic and glass are a very small fraction, although they provide most of the contamination. If you want to help the environment only put very clean, rigid plastic bottles, with their caps on, in the recycle bin. Glass must also be very clean, intact and have a lid.

Roughly ten percent of our recycling, in the U.S.A., is composted. Most of this is yard and farm waste, the rest is mostly discarded food. Thirteen percent of the waste is incinerated in large industrial incinerators that recover some energy by generating electricity.

Incineration

As the quality of recycled materials has decreased, causing recycling costs to increase, incineration has become more popular worldwide. When western countries began exporting their trash, total world pollution did not decrease, it just moved to Africa and southeast Asia. It is no wonder that these areas rebelled. As noted above, for metal, plastic or glass to be recycled it must be intact and clean, when processed, whether in a foreign country or at home, huge amounts of water are required, this creates a lot of waste water that must be processed before it is discharged. It is this polluted wastewater that China objected to most, the recycling communities did not always process the wastewater prior to discharging it to the ocean or a river.

As explained by Mikko Paunio, in his GWPF report, Saving the Oceans, and the plastic recycling crisis, plastic, and most other so-called “recyclables” are not truly recyclable. For these materials, incineration is best according to Paunio (see pages 2-4 of the cited report). It is safer because it does not require the waste to be sorted and better for the environment because there is no wastewater from washing the trash. Modern incinerators generate electricity and collect the fly ash from incineration in bag houses, so it doesn’t enter the atmosphere and can be disposed of properly. The bottom ash, the ash that does not become airborne, can be processed to extract valuable metals. The process reduces the volume of trash to about 15%-20% of the original, it also kills harmful bacteria and reduces many pollutants to safe component molecules. Harmful air pollutant chemicals, like mercury, SO2 or carbon monoxide, can be trapped or converted into safe compounds in pollution control equipment and made harmless, just as they are in modern coal-fired power plants.

Once the ash is processed for valuable metals, it is taken to a landfill for disposal, but occupies only one-fifth or less of the space it would have occupied before it was incinerated, and the ash is safer for the environment. Some misguided politicians have crippled waste incineration with costly regulatory demands, to the detriment of their countries. The most egregious example was in Italy in 2000. They prohibited (in effect, through regulations) incineration of trash and as a result their landfills quickly filled up. That meant local trash haulers had to stop collecting trash and the only option was to burn it in the open air without pollution control equipment and the Campania region became heavily polluted with dioxins (Paunio, GWPF Note 16 2019, page 3). When considering incineration of waste, it is important to consider the alternatives and their effects.

Plastic in the Oceans

According to Paunio (Paunio, GWPF Briefing 32 2018) the problem of plastic pollution in the oceans is mainly due to plastic from China and southeast Asia. However, much of the plastic dumped in the ocean in Asia, originally came from the United States and Europe and was simply shipped to China and southeast Asia as “recyclable.” Only a fraction of the plastic disposed of in western countries and shipped to Asia could be recycled, the rest wound up in rivers and in the ocean. This was not the reason that Asia stopped receiving the plastic waste, however, the reason they stopped all or most of the shipments was the water pollution created by cleaning the trash that was already supposed to be clean.

Paunio calls the plastic pollution in the oceans a crisis, but he does not offer any evidence, he simply assumes the plastic in the oceans is a crisis. His focus is on alternatives to recycling plastic, as the recycling is not working. For a discussion of the ocean pollution problem itself, we turn to another report, the Analysis of Greenpeace’s business model and philosophy, by an international team of researchers (Connolly, et al. 2018, page 29). A tiny amount of microplastic fragments are present in most ocean basins.

For most of the oceans, the concentrations of microplastics are negligible and almost undetectable. In a few “ocean gyres” collections of plastic waste fragments are found in higher concentrations, perhaps up to a few hundred tiny fragments per square mile. Figure 2 shows all the fragments collected from one pass of a trawler through the heart of one of the so-called “Oceanic Garbage Patches,” in the South Atlantic Gyre.

Figure 2. All the plastic fragments collected in a pass, with a fine mesh net, through the South Atlantic gyre “Garbage Patch.” The largest fragment is less than 1.5 cm. across. They found 110 pieces in a 0.5-mile pass. All 110 pieces would not fill a thimble. (Connolly, et al. 2018, page 33).

Studies suggest that larger, more visible plastic bottles, nets, ropes etc. are from fishing boats. The microplastic is mostly from developing nations, especially Asian nations. The largest contributors to ocean plastics are China, Indonesia, Malaysia, Philippines, and Vietnam. Until the recent changes took effect, these countries were also the largest importers of recyclable plastics. As we can see the samples collected from the “Great Ocean Garbage Patches” do not support the media hyperbole.

Conclusions

While the idea of recycling is attractive, it has not been effective, nor has it helped the environment. If everyone were extremely careful about what they put in their recycle bins, washed it carefully, replaced the lids on jars and bottles, kept the paper that they recycled dry and clean, it might help. But, this is unrealistic, people will throw half-drunk sodas and beers into the bins, along with wet newspapers, soiled aluminum foil and plastic; then the mess must be sorted out, cleaned and most of it will go into the regular trash anyway. A common complaint among the recycling public is, “Why should I wash my trash?” The simplest answer is, “If you don’t it will not be recycled.”

The reason developing nations will not accept our recyclables anymore, is that they are dirty, and it takes too much water to clean them. The resulting wastewater, from cleaning the recyclables, is dangerously polluted and too expensive to prepare for discharge. Worse, in some countries the water used to clean the recyclables is not processed at all and discharged directly into rivers or the ocean with all the contaminants still in it. This fouls the rivers and oceans, endangers the fish and public health.

Greenpeace and other environmental organizations are spreading nonsense about the supposed “ocean garbage patches,” when they are not a problem at all. Not to the fish, China, southeast Asia or the U.S., Japan and Europe. The problem is the wastewater created when we clean our trash or export it to other countries that must clean it. Even after cleaning, a lot of the plastic and glass cannot be recycled as it is the wrong kind. Recycling just is not working well.

Incineration is a far better solution. No sorting or wasteful cleaning is required, all trash can be burned safely in a very environmentally friendly way in modern incinerators equipped with proper pollution control equipment (Paunio, GWPF Briefing 32 2018, page 4).

UK airports must shut to reach 2050 climate target

By Paul Homewood

 

h/t Keith Holland

 

UK airports must shut, says UK Govt backed research group:

All UK airports must close by 2050 for the country to reach its target of net zero climate emissions by then, scientists say.

LONDON, 18 February, 2020 − If it is to achieve its target of net zero climate emissions by 2050, all UK airports must close by mid-century and the country will have to make other drastic and fundamental lifestyle changes, says a report from a research group backed by the government in London.

With the UK due to host this year’s round of crucial UN climate talks in Glasgow in November, a group of academics has embarrassed the British government by showing it has currently no chance of meeting its own legally binding target to reduce greenhouse gas emissions to nothing within 30 years.

Their report, Absolute Zero, published by the University of Cambridge, says no amount of government or public wishful thinking will hide the fact that the country will not reach zero emissions by 2050 without barely conceivable changes to policies, industrial processes and lifestyles. Its authors include colleagues from five other British universities.

All are members of a group from UK Fires, a research programme sponsored by the UK government, aiming to support a 20% cut in the country’s true emissions by 2050 by placing resource efficiency at the heart of its future industrial strategy. The report was paid for under the UK Fires programme.

As well as a temporary halt to flying, the report also says British people cannot go on driving heavier cars and turning up the heating in their homes.

The government, industry and the public, it says, cannot continue to indulge themselves in these ways in the belief that new technologies will somehow save them – everyone will have to work together change their way of life.

Because electric or zero-emission aircraft cannot be developed in time, most British airports will need to close by the end of this decade, and all flying will have to stop by 2050 until non-polluting versions are available.

Electrification of surface transport, rail and road, needs to be rapid, with the phasing out of all development of petrol and diesel cars immediately. Even if all private cars are electric, the amount of traffic will have to fall to 60% of 2020 levels by 2050, and all cars will have to be smaller.

The report also suggests that ships, currently heavy users of fossil fuels, need to convert to electric propulsion in order to allow for necessary imports and exports.

Not enough time

The reasoning behind the report is that technologies to cut greenhouse gas emissions, like carbon capture and storage, will not be developed in time and on a large enough scale to make a difference to emission reductions by 2050.

Nor is it any use exporting energy-intensive industries like steel-making, because the emissions will still take place abroad.

Instead, homegrown industries need to be developed that use no fossil fuels but are powered by electricity. The report says blast furnaces need to be phased out and replaced by existing technologies that recycle steel using renewable electricity.

It calls for public debate and discussion about the lifestyle changes that will be essential. Although such luxuries as flying away on holiday and driving large cars will have to be foregone, and eating beef and lamb curtailed, the scientists say that life could be just as rich as today.

They say: “… sports, social life, eating, hobbies, games, computing, reading, TV, music, radio, volunteering (and sleeping!) We can all do more of these without any impact on emissions”.

Offsets won’t work

They want the public to help by lobbying for airport closures, more trains, no new roads and more renewable electricity.

The report insists that the government should not try to hide any of its emissions by importing goods: “The UK is responsible for all emissions caused by its purchasing, including imported goods, international flights and shipping.”

Nor can there be any meaningful “carbon offsets.” The only short-term option we have of reducing emissions – at least by 2050 – is to plant trees. “Even a massive increase in forestry would only have a small effect compared to today’s emissions.”

The authors comment: “There are no invisible solutions to climate change. We urgently need to engage everyone in the process of delivering the changes that will lead to zero emissions.” − Climate News Network

And shutting airports will only be the start, according to the authors, who want barely conceivable changes to policies, industrial processes and lifestyles.

Car traffic must fall by 60%, eating of beef and lamb be curtailed, and a drastic cut in imported goods enforced as well, not just because of the imported emissions but also because of the shipping.

Nowhere in this ridiculous study is there any acknowledgement of the fact that the rest of the world will carry on as normal.

Of course, we’ll end up like North Korea, but that’s OK, because we can still listen to the radio, volunteer and sleep – all without increasing emissions. Indeed, we’ll probably have to stop in bed all day, just to keep warm in winter, when our wonderful renewable energy packs up.

What a fun life that will be!

All of this raises two points:

1) Why is the government giving good money to produce reports like this one?

2) The author of Climate News Network, who ran this piece is Paul Brown. He also happens to be a founding editor of Climate News Network, and is a former environment correspondent of The Guardian, and still writes columns for the paper.

Amazing how the alarmist merry-go-round works!

‘We Can Save Earth’: Amazon’s Jeff Bezos Announces $10-Billion Climate Action Plan

From The Daily Caller

Daily Caller News Foundation logoDaily Caller News Foundation logo

Chris White Tech Reporter

February 17, 2020 3:54 PM ET

Amazon CEO Jeff Bezos announced Monday a $10-billion plan to tackle what he says is the most important threat facing human beings: man-made global warming.

Bezos is pressing forward with what he dubbed the Bezos Earth Fund, an initiative he hopes will spur investments to find climate solutions. His statement came as Amazon workers continue to threaten a mass walkout over the company’s supposed lack of climate action.

“Climate change is the biggest threat to our planet,” the billionaire wrote in a statement. “We can save Earth. It’s going to take collective action from big companies, small companies, nation states, global organizations, and individuals.”

Bezos noted that he is providing a $10-billion infusion of cash to kick off the initiative.

“Earth is the one thing we all have in common — let’s protect it together,” he added. (RELATED: Amazon Has Spent Nearly $1.5 Million On Seattle’s City Council Races In 2019)

Amazon employees created a group called Employees for Climate Justice, which published a statement in January updating its plans to allow company employees to speak to the press in September.

More than 1,000 employees walked off their jobs in September 2019 in support of a national march calling on Bezos to do more on global warming.

“Now is a time when we need to have communications policies that let us speak honestly about our company’s role in the climate crisis,” Karen Costa, a user experience principal designer at Amazon, said in a statement in January.

Bezos’s worth fell to $111.4 billion in 2019 after he divorced his wife in April of that year, according to the Bloomberg Billionaires Index. He lost more money than any other human on the planet that year. He was worth roughly $150 billion before the split.

Work Begins On Key Climate Report Overseen By Trump Administration

The next National Climate Assessment is beginning to take shape at a time when President Trump warned world leaders to reject “alarmists” and as his conservative allies make plans to intervene in the report’s preparation to question the findings of mainstream scientists.

The Fifth National Climate Assessment is scheduled for release in 2022, about halfway through Trump’s potential second term. Planning for the report is already underway, with requests to researchers to submit their work and a project leader expected to be chosen within a few months, according to Donald Wuebbles, a climate scientist at the University of Illinois who oversaw the last assessment.

The White House stands to have an influential role in the report’s construction through the Office of Science and Technology Policy, which is overseen by Trump’s science adviser, Kelvin Droegemeier. Wuebbles said Droegemeier, an extreme-weather expert whom he has known for years, will work to produce an accurate assessment that’s free of Trump’s erroneous assertions about climate change.

“Kelvin would fight that,” Wuebbles said.

But critics of climate science close to the White House believe the effort could take a more adversarial approach compared with earlier versions. Steve Koonin, a physics professor at New York University, said he has pitched Droegemeier on the idea of incorporating a red-team review into the National Climate Assessment. The exercise could allow science critics to use discredited theories to challenge consensus research on rising temperatures, scientists have said.

Koonin was part of the aborted White House effort to conduct an adversarial review of the last National Climate Assessment. Though that effort failed, Koonin is confident that it “chastened” White House officials against releasing the 2022 report without challenging alarming new climate findings.

“I’d like to see a good, hard scrub of the thing, done in an open way,” Koonin said in an interview. “I hope we have other ways of getting an honest portrayal of the science out there. I haven’t given up.”

Officials in the White House science office did not respond to a request for comment.

William Happer, a former director on the National Security Council who led the failed attempt last year to formally dispute mainstream science through a red-team process, told McClatchy last week that he hopes to be a contributing author of the next National Climate Assessment.

Happer previously revealed that the Trump administration obstructed the timing of the Fourth National Climate Assessment, which was started during the Obama administration, by releasing it the day after Thanksgiving. He also said the president was angry that it had been released at all.

The fourth assessment went through two reviews involving multiple federal agencies with expertise in climate science as well as additional rounds of scrutiny from experts assembled at the National Academies of Sciences, Engineering and Medicine. It also went through a public review that generated more than 3,400 comments.

Scientists involved in drafting the last assessment are concerned that the process could be politicized. The notion of having two teams — one red and one blue — argue over the science is inherently political, said Katharine Hayhoe, a climate scientist at Texas Tech University and a lead author of the fourth assessment.

“There is no blue team, the entire premise is based on a straw man, and the straw man is that a thermometer gives you a different answer depending on how you vote,” she said. “The whole argument is based on an absolute fallacy that somehow science is different when you look at it through different lenses and it gives you different answers.”

Hayhoe acknowledged, however, that the process of writing the National Climate Assessment is due for an update. She said more than half of its revelations are foundational and haven’t changed since the last assessment was written.

Instead, she said, there’s plenty of room to reveal noteworthy scientific discoveries as incremental and ongoing updates. Hayhoe said the next version of the report should continue to address climate attribution for individual events, such as the Australian wildfires or a particular hurricane.
