00:00:00,000 --> 00:00:03,040
Okay, Chelsea, for a Fringy Mini this week,

2
00:00:03,040 --> 00:00:06,900
I generally have news that I say has to be conveyed to people,

3
00:00:06,900 --> 00:00:08,120
not that it's bad news.

4
00:00:08,120 --> 00:00:10,120
This one I think I can actually say

5
00:00:10,120 --> 00:00:12,280
is somewhat good news, in fact.

6
00:00:12,280 --> 00:00:14,600
Well, wow, that's incredible.

7
00:00:14,600 --> 00:00:15,880
Yeah.

8
00:00:15,880 --> 00:00:19,360
And I only had to put a little qualifier of somewhat.

9
00:00:19,360 --> 00:00:24,020
I feel like we're actually using this source a lot these days.

10
00:00:24,020 --> 00:00:25,400
It's fizz.org.

11
00:00:25,400 --> 00:00:28,940
This article was posted on October 22nd, 2023.

12
00:00:28,940 --> 00:00:31,640
So very new from recording date.

13
00:00:31,640 --> 00:00:35,200
And the article is by Paul Boisvert.

14
00:00:35,200 --> 00:00:36,400
And it is called,

15
00:00:36,400 --> 00:00:40,560
Scientists Close the Cycle on Recycling Mixed Plastics.

16
00:00:40,560 --> 00:00:43,400
Okay, that sounds promising.

17
00:00:43,400 --> 00:00:46,800
I feel like you're just setting me up to be disappointed.

18
00:00:46,800 --> 00:00:48,000
I don't know.

19
00:00:48,000 --> 00:00:50,000
It's gonna have a twist at the end.

20
00:00:50,000 --> 00:00:52,560
That's gonna be like, and the earth is ending.

21
00:00:52,560 --> 00:00:55,000
Yes, tomorrow, in fact.

22
00:00:55,000 --> 00:00:56,840
And this was published yesterday.

23
00:00:56,840 --> 00:01:00,280
No, little of the mixed consumer plastics thrown away

24
00:01:00,280 --> 00:01:03,280
or placed in recycle bins actually end up being recycled.

25
00:01:03,280 --> 00:01:06,120
We do know that from our previous recycling episode.

26
00:01:06,120 --> 00:01:08,680
If you haven't heard it, there's a recycling episode.

27
00:01:08,680 --> 00:01:10,880
I think it's called recycling topic ideas

28
00:01:10,880 --> 00:01:11,720
or something like that.

29
00:01:11,720 --> 00:01:12,960
And you have just listened to all episodes

30
00:01:12,960 --> 00:01:14,240
if you can't find it.

31
00:01:14,240 --> 00:01:16,840
Nearly 90% is buried in landfills

32
00:01:16,840 --> 00:01:18,680
or incinerated at commercial facilities

33
00:01:18,680 --> 00:01:21,200
that generate greenhouse gases and airborne toxins.

34
00:01:21,200 --> 00:01:23,360
Neither outcome is ideal for the environment.

35
00:01:23,360 --> 00:01:25,600
Why are more mixed plastics recycled?

36
00:01:25,600 --> 00:01:27,080
It's usually easier and less expensive

37
00:01:27,080 --> 00:01:28,440
to make new plastic products

38
00:01:28,440 --> 00:01:31,480
than reclaimed, sort, and recycle used ones.

39
00:01:31,480 --> 00:01:33,860
Conventional recycling of mixed plastics

40
00:01:33,860 --> 00:01:36,480
has previously meant manually or mechanically

41
00:01:36,480 --> 00:01:37,600
separating the plastics

42
00:01:37,600 --> 00:01:39,560
according to their constituent polymers.

43
00:01:39,560 --> 00:01:41,440
Addressing the issue, scientists at the Department

44
00:01:41,440 --> 00:01:44,080
of Energy's Oak Ridge National Laboratory

45
00:01:44,080 --> 00:01:46,600
use carefully planned chemical design,

46
00:01:46,600 --> 00:01:48,800
neutron scattering, and high performance computing

47
00:01:48,800 --> 00:01:52,500
to help develop a new catalytic recycling process.

48
00:01:52,500 --> 00:01:54,800
The catalyst selectively and sequentially

49
00:01:54,800 --> 00:01:56,520
deconstructs multiple polymers

50
00:01:56,520 --> 00:02:00,320
and mixed plastics into pristine monomers, molecules,

51
00:02:00,320 --> 00:02:03,800
that react with other monomer molecules to form a polymer.

52
00:02:03,800 --> 00:02:05,800
A process offers a promising strategy

53
00:02:05,800 --> 00:02:07,840
for combating global plastic waste,

54
00:02:07,840 --> 00:02:10,300
such as bottles, packaging, foam, and carpets.

55
00:02:10,300 --> 00:02:13,520
The research analysis published in Materials Horizons

56
00:02:13,520 --> 00:02:15,680
compared using the new multi-purpose catalyst

57
00:02:15,680 --> 00:02:19,040
to using individual catalysts for each type of plastic.

58
00:02:19,040 --> 00:02:22,720
The new catalyst would generate up to 95% fewer greenhouse

59
00:02:22,720 --> 00:02:25,960
gases required up to 94% less input energy

60
00:02:25,960 --> 00:02:28,360
and results in up to 96% reduction

61
00:02:28,360 --> 00:02:30,120
in fossil fuel consumption.

62
00:02:30,120 --> 00:02:32,800
Quote, our approach involves a tailored synthetic

63
00:02:32,800 --> 00:02:35,800
organo-catalyst, a compound comprised

64
00:02:35,800 --> 00:02:37,200
of small organic molecules

65
00:02:37,200 --> 00:02:40,360
that facilitates organic chemical transformations.

66
00:02:40,360 --> 00:02:42,880
The organo-catalyst can convert batches

67
00:02:42,880 --> 00:02:45,380
of mixed plastic waste into valuable monomers

68
00:02:45,380 --> 00:02:48,140
for reuse in producing commercial-grade plastics

69
00:02:48,140 --> 00:02:49,840
and other valuable materials.

70
00:02:49,840 --> 00:02:52,120
This exceptionally efficient chemical process

71
00:02:52,120 --> 00:02:55,160
can help us close the loop for recycling mixed plastics

72
00:02:55,160 --> 00:02:58,720
by replacing first use monomers with recycled monomers,

73
00:02:58,720 --> 00:03:02,960
said Tom Inori Saito, an ORNL synthetic polymer chemist

74
00:03:02,960 --> 00:03:04,600
and corresponding author.

75
00:03:04,600 --> 00:03:05,760
The quote does continue on,

76
00:03:05,760 --> 00:03:08,280
today nearly all plastics are made from fossil fuels

77
00:03:08,280 --> 00:03:12,280
using first use monomer made by energy-intensive processes.

78
00:03:12,280 --> 00:03:14,760
Establishing this kind of closed loop recycling,

79
00:03:14,760 --> 00:03:17,940
if used globally, could reduce annual energy consumption

80
00:03:17,940 --> 00:03:21,200
by up to 3.5 billion barrels of oil.

81
00:03:21,200 --> 00:03:22,480
End quote.

82
00:03:22,480 --> 00:03:25,640
The new organo-catalyst has proven to efficiently

83
00:03:25,640 --> 00:03:27,400
and quickly deconstruct multiple polymers

84
00:03:27,400 --> 00:03:28,520
in around two hours.

85
00:03:28,520 --> 00:03:31,160
Such polymers include those used in materials

86
00:03:31,160 --> 00:03:34,000
such as safety goggles, foams, water bottles,

87
00:03:34,000 --> 00:03:36,200
and ropes or fishing nets,

88
00:03:36,200 --> 00:03:38,320
which together comprise about 30%

89
00:03:38,320 --> 00:03:40,000
of global plastic production.

90
00:03:40,000 --> 00:03:42,960
Until now, no single catalyst has been shown

91
00:03:42,960 --> 00:03:46,000
to be effective on all four of these polymers.

92
00:03:46,000 --> 00:03:48,560
The process provides many environmental advantages

93
00:03:48,560 --> 00:03:51,560
by replacing harsh chemicals for deconstructing polymers

94
00:03:51,560 --> 00:03:53,960
as well as offering good selectivity,

95
00:03:53,960 --> 00:03:57,480
thermal stability, non-volatility, and low flammability.

96
00:03:57,480 --> 00:03:59,600
Its effectiveness against multiple polymers

97
00:03:59,600 --> 00:04:01,880
also makes it useful to be for deconstructing

98
00:04:01,880 --> 00:04:04,440
the increasing amounts of multi-component plastics,

99
00:04:04,440 --> 00:04:07,240
such as composites and multi-layer packaging.

100
00:04:07,240 --> 00:04:10,480
Small angle neutron scattering at ORNLs,

101
00:04:10,480 --> 00:04:12,160
sphalation neutron source,

102
00:04:12,160 --> 00:04:14,840
was used to help confirm the formation

103
00:04:14,840 --> 00:04:17,520
of deconstructed monomers from the waste plastics.

104
00:04:17,520 --> 00:04:19,960
And the method scatters neutrons at small angles

105
00:04:19,960 --> 00:04:22,720
to categorize the structure at different levels of detail

106
00:04:22,720 --> 00:04:25,240
from nanometers to fractions of a micrometer.

107
00:04:25,240 --> 00:04:26,800
There is more to it than this,

108
00:04:26,800 --> 00:04:28,840
but I suggest you go read the rest of the article.

109
00:04:28,840 --> 00:04:31,600
I thought it was super uplifting in ways.

110
00:04:31,600 --> 00:04:35,360
And that's not usually my MO on these things.

111
00:04:35,360 --> 00:04:37,560
I know sometimes I go to the recycling bin

112
00:04:37,560 --> 00:04:39,680
and I pull out things that don't fit.

113
00:04:39,680 --> 00:04:42,560
Just put them to the side so that it's not all garbage,

114
00:04:42,560 --> 00:04:44,200
but that's promising.

115
00:04:44,200 --> 00:04:48,160
I wonder how it would be implemented

116
00:04:48,160 --> 00:04:49,560
and if it would be everywhere

117
00:04:49,560 --> 00:04:51,960
or if they say it was too expensive.

118
00:04:51,960 --> 00:04:55,000
Well, it says it's going to be cheaper long term,

119
00:04:55,000 --> 00:04:57,240
but of course we will have to wait and see.

120
00:04:57,240 --> 00:04:59,480
Like I've said, when you hear stories about,

121
00:04:59,480 --> 00:05:02,120
oh, like that cured cancer and then nothing comes of it.

122
00:05:02,120 --> 00:05:03,880
It generally ends up that the studies

123
00:05:03,880 --> 00:05:05,600
either didn't go the way they wanted to,

124
00:05:05,600 --> 00:05:09,640
or it ends up being too not cost effective to go about it.

125
00:05:09,640 --> 00:05:12,640
So I guess cost effective shouldn't be a thing

126
00:05:12,640 --> 00:05:14,840
in the face of like global warming

127
00:05:14,840 --> 00:05:16,560
because we're destroying the planet.

128
00:05:16,560 --> 00:05:17,880
Overall, it just-

129
00:05:17,880 --> 00:05:19,720
Money won't exist afterwards.

130
00:05:19,720 --> 00:05:22,840
Let's us have our planet for a little bit longer.

131
00:05:22,840 --> 00:05:23,680
Yeah.

132
00:05:23,680 --> 00:05:25,960
Okay, well, that's good.

133
00:05:25,960 --> 00:05:27,680
Yeah, at least there is potential

134
00:05:27,680 --> 00:05:29,280
for good news down the road.

135
00:05:29,280 --> 00:05:32,080
This is good news now, but potential good news.

136
00:05:32,080 --> 00:05:33,880
So let's raise spirits.

137
00:05:33,880 --> 00:05:36,360
Raise spirits, sink ships or something like that.

138
00:05:36,360 --> 00:05:38,200
I can't remember how the sayings go.

139
00:05:38,200 --> 00:05:40,040
Yeah, let's sink ships.

140
00:05:40,040 --> 00:05:41,520
Yeah, let's sink ships.

141
00:05:41,520 --> 00:05:44,120
And then we'll raise them on Friday.

142
00:05:44,120 --> 00:05:46,200
48 hours underwater is what you guys get.

143
00:05:46,200 --> 00:05:48,760
That's how tight you are at the end of the day.

144
00:05:48,760 --> 00:05:50,520
And global warming.

145
00:05:50,520 --> 00:06:12,520
Yes, anyhow, bye.
