Plastics Recycling

Debate between Barry Sheerman and Vince Cable

Tuesday 23rd April 2019 Westminster Hall

[Sir Vince Cable (Twickenham) (LD)]

I beg to move,

That this House has considered plastics recycling.

I am grateful for the opportunity to lead an environmental debate after an environmental weekend. I was lucky enough to be part of the Opposition leaders’ meeting with Greta Thunberg this morning, which reminded us all that there is a world beyond Brexit.

I want to narrow the discussion to the issue of plastics recycling. I know it is well-trodden territory in many ways. In the past 20 years, a whole body of British legislation and policy has been built on the waste directive. The Department for Environment, Food and Rural Affairs has four consultations in varying stages of completion. We will no doubt touch on some of those issues. There is also a great deal of very good documentation, including the excellent paper from the Library on plastic waste.

I acknowledge from the outset that the issue is superficially simple, but actually extremely complex. There are many different kinds of plastic, each with different approaches with different costs and benefits. There are many useful and necessary applications. For example, there is an enormous distinction between macroplastics and microplastics. The macroplastics that we talk about in public debate include plastic bottles. Microplastics are built into such things as our clothing and the wear of tyres, and may have even bigger environmental impacts.

I approach the subject from three different directions. First, like many Members, I have been lobbied, through vast numbers of letters, by local schoolchildren about the issues to do with plastics in the ocean. They asked me to raise the issue in Parliament, which I am now doing. In many cases, they were highly motivated by seeing the David Attenborough series, “The Blue Planet”. Those arguments have been well rehearsed and I do not need to develop them.

In researching for today, I found some of the facts—perhaps we should call them factoids—surrounding the subject very striking. One was that while plastics are generally very light and buoyant, we are heading to a situation where the weight of plastics in the ocean will soon exceed the total weight of fish. Even more strikingly —it is authoritative, because it came out of a Government press release—every year, the ingestion of plastics by fish and entanglement result in the loss of a million seabirds and 100,000 sea mammals. That is extraordinary. Children have every reason to be very exercised.

[Mr Barry Sheerman (Huddersfield) (Lab/Co-op)]

Would the right hon. Gentleman agree—it is 25 years this year since I started the environmental organisation, the Socialist Environment and Resources Association—that we consistently have to go right back to the manufacture of plastics? I beg him to meet Professor Steve Evans at the institute for sustainable manufacture at Cambridge University. Changing what we manufacture is at the heart of a long-term resolution.

[Sir Vince Cable]

I would be delighted to meet the professor, if he is happy to meet me. The hon. Gentleman is right that we are often looking at the wrong end of the process. We should be looking at the origins.

--- Later in debate ---

[Sir Vince Cable]

That is right; it is basic market principles allied to the environment. The Government announced in last year’s Budget that they would proceed with that. There is a consultation, which we will no doubt hear more about from the Minister.

[Mr Sheerman]

Before the right hon. Gentleman moves on from that very good answer to that very good suggestion, may I suggest that real waste experts—people who know about plastics and waste—say, “Make waste valuable and it will be recycled.” If there is no money and no reward for picking it up and recycling it, we are on to a loser. Greta Thunberg wants action now. Can we not make waste valuable quickly?

[Sir Vince Cable]

That is correct, but with one qualification: it also makes the export of waste valuable. I will come back to the particular problem associated with that in a moment.

In the short time that I have, I will put three specific issues to the Minister. The first concerns data, which has already been raised by the Environmental Audit Committee. There are vast disparities in the numbers that make it very difficult to make sense of what is happening. To cite a few examples, I think the official figures are that 1.5 million tonnes of plastic waste is generated every year in the UK. The World Wildlife Fund estimates that it is about 5 million tonnes, and Economia, which does consultancy in this area, estimates that it is about 3 million to 4 million tonnes. Perhaps they are using different definitions, but we need clarity, because at the moment there is wild variation.

That also applies to what is being achieved in terms of recycling and waste disposal. I understand that the official figures are that 91% of waste is either recycled or recovered in other ways—the definition of recovery includes incineration and export—and only 9% goes to landfill. However, again, the World Wildlife Fund has wildly different numbers. It suggests that 48% goes to landfill, 20% to 30% is recycled, and 22% is used as an energy source. I do not know why there is that difference. Again, it may be a definitional question, but some clear and unambiguous statement from the Government about the position would be very helpful.
