The Pig Idea: campaign looks to pigs to tackle food waste



The Pig Idea is a new initiative to feed pigs with food wasted by supermarkets and kitchens – a practice banned by the European Union following the spread of mad cow disease. Ilaria Bertini investigates.

Following research that shows up to half of global food never reaches a human stomach, a campaign is calling for wasted food to be given to animals – specifically pigs.

Pigs have been used for centuries to dispose of organic waste, at least until this practice was banned by the EU in 2001, amid fears that it could lead to diseases such as bovine spongiform encephalopathy (BSE), also known as mad cow disease, which was linked to the presence of animal protein in the food given to cows.

However, campaigners from the Pig Idea claim that the ban should be lifted for pigs, as they are omnivores and controlled feeding on food waste would help reduce the cost of imported grains such as soya – whose production is 97% used for animal feed.

Edd Colbert, the Pig Idea’s campaign co-ordinator, told Blue & Green Tomorrow, “The Pig Idea at no point advocates ad-hoc, backyard swill feeding, but instead calls for the establishment of a robustly monitored and regulated food waste feed industry.

“The British foot and mouth outbreak of 2001 that resulted in the ban of feeding animal byproducts and catering waste to omnivorous non-ruminant livestock (pigs and chickens) allegedly stemmed from one farmer slacking in his swill preparation leading to the inclusion of infected meat products in his pigs’ diet.

“The proposed eco-feed industry would source food waste from restaurants, institutional kitchens and catering facilities and abattoirs to then be processed for a required time and at a specified temperature to ensure all risks of pathogens and disease had been removed as it happens in  South Korea, Japan, North America and China. This practice is proven to be completely bio-secure and results in nutritious feed for the pigs with no risk of spreading diseases to animals or consumers.”

The campaign aims to tackle food waste, lower the costs for farmers and reduce the environmental footprint of animal farming, which in 2006 was estimated by the UN to be greater than the transport sector.

Indeed, as Colbert noted, pig manure has been responsible for many cases of severe pollution especially to waterways and caused eutrophication for instance in the US.

However, pigs can play a valuable role in our ecosystem both as fertilisers and as food waste recyclers to create pork”, he said.

When reared sustainably, under high welfare conditions, pigs do not require the same amount of chemicals in their diets, nor the high levels of antibiotics.”

Colbert added that the Pig Idea is aware of the high environmental and social cost of animal farming: “Feeding food to livestock that has been grown and could be fed to the world’s hungry people is not only immoral but it is also unsustainable. People do need to reduce their meat consumption as a whole and the Pig Idea is a proud supporter of the Eating Better campaign which seeks to change the way we think about meat, both in terms of quality and quantity.”

The Pig Idea campaign also brushed off claims that it was somehow suggesting edible food should be given to animals instead of people in need, with Colbert saying, “When food is being wasted throughout the supply chain that cannot be consumed by people, it should instead be being fed to pigs and chickens.”

In between the horsemeat scandal which occurred in the UK earlier this year, the EU announced it was considering lifting the ban on feeding animals with processed animal proteins (PAPs) – which include intestine, bones, blood and feathers – in relation to pigs and chickens, starting from 2014.

Will Self-Driving Cars Be Better for the Environment?

Technologists, engineers, lawmakers, and the general public have been excitedly debating about the merits of self-driving cars for the past several years, as companies like Waymo and Uber race to get the first fully autonomous vehicles on the market. Largely, the concerns have been about safety and ethics; is a self-driving car really capable of eliminating the human errors responsible for the majority of vehicular accidents? And if so, who’s responsible for programming life-or-death decisions, and who’s held liable in the event of an accident?

But while these questions continue being debated, protecting people on an individual level, it’s worth posing a different question: how will self-driving cars impact the environment?

The Big Picture

The Department of Energy attempted to answer this question in clear terms, using scientific research and existing data sets to project the short-term and long-term environmental impact that self-driving vehicles could have. Its findings? The emergence of self-driving vehicles could essentially go either way; it could reduce energy consumption in transportation by as much as 90 percent, or increase it by more than 200 percent.

That’s a margin of error so wide it might as well be a total guess, but there are too many unknown variables to form a solid conclusion. There are many ways autonomous vehicles could influence our energy consumption and environmental impact, and they could go well or poorly, depending on how they’re adopted.

Driver Reduction?

One of the big selling points of autonomous vehicles is their capacity to reduce the total number of vehicles—and human drivers—on the road. If you’re able to carpool to work in a self-driving vehicle, or rely on autonomous public transportation, you’ll spend far less time, money, and energy on your own car. The convenience and efficiency of autonomous vehicles would therefore reduce the total miles driven, and significantly reduce carbon emissions.

There’s a flip side to this argument, however. If autonomous vehicles are far more convenient and less expensive than previous means of travel, it could be an incentive for people to travel more frequently, or drive to more destinations they’d otherwise avoid. In this case, the total miles driven could actually increase with the rise of self-driving cars.

As an added consideration, the increase or decrease in drivers on the road could result in more or fewer vehicle collisions, respectively—especially in the early days of autonomous vehicle adoption, when so many human drivers are still on the road. Car accident injury cases, therefore, would become far more complicated, and the roads could be temporarily less safe.


Deadheading is a term used in trucking and ridesharing to refer to miles driven with an empty load. Assume for a moment that there’s a fleet of self-driving vehicles available to pick people up and carry them to their destinations. It’s a convenient service, but by necessity, these vehicles will spend at least some of their time driving without passengers, whether it’s spent waiting to pick someone up or en route to their location. The increase in miles from deadheading could nullify the potential benefits of people driving fewer total miles, or add to the damage done by their increased mileage.

Make and Model of Car

Much will also depend on the types of cars equipped to be self-driving. For example, Waymo recently launched a wave of self-driving hybrid minivans, capable of getting far better mileage than a gas-only vehicle. If the majority of self-driving cars are electric or hybrids, the environmental impact will be much lower than if they’re converted from existing vehicles. Good emissions ratings are also important here.

On the other hand, the increased demand for autonomous vehicles could put more pressure on factory production, and make older cars obsolete. In that case, the gas mileage savings could be counteracted by the increased environmental impact of factory production.

The Bottom Line

Right now, there are too many unanswered questions to make a confident determination whether self-driving vehicles will help or harm the environment. Will we start driving more, or less? How will they handle dead time? What kind of models are going to be on the road?

Engineers and the general public are in complete control of how this develops in the near future. Hopefully, we’ll be able to see all the safety benefits of having autonomous vehicles on the road, but without any of the extra environmental impact to deal with.

When you have a growing family, it often feels like you’re in this weird bubble that exists outside of mainstream society. Whereas everyone else seemingly has stability, your family dynamic is continuously in flux. Having said that, is it even possible to buy an eco-friendly vehicle that’s also practical?

What to Look for in a Green, Family-Friendly Vehicle?

As a single person or young couple without kids, it’s pretty easy to buy a green vehicle. Almost every leading car brand has eco-friendly options these days and you can pick from any number of options. The only problem is that most of these models don’t work if you have kids.

Whether it’s a Prius or Smart car, most green vehicles are impractical for large families. You need to look for options that are spacious, reliable, and comfortable – both for passengers and the driver.

5 Good Options

As you do your research and look for different opportunities, it’s good to have an open mind. Here are some of the greenest options for growing families:

1. 2014 Chrysler Town and Country

Vans are not only popular for the room and comfort they offer growing families, but they’re also becoming known for their fuel efficiency. For example, the 2014 Chrysler Town and Country – which was one of CarMax’s most popular minivans of 2017 – has Flex Fuel compatibility and front wheel drive. With standard features like these, you can’t do much better at this price point.

2. 2017 Chrysler Pacifica

If you’re looking for a newer van and are willing to spend a bit more, you can go with Chrysler’s other model, the Pacifica. One of the coolest features of the 2017 model is the hybrid drivetrain. It allows you to go up to 30 miles on electric, before the vehicle automatically switches over to the V6 gasoline engine. For short trips and errands, there’s nothing more eco-friendly in the minivan category.

3. 2018 Volkswagen Atlas

Who says you have to buy a minivan when you have a family? Sure, the sliding doors are nice, but there are plenty of other options that are both green and spacious. The new Volkswagen Atlas is a great choice. It’s one of the most fuel-efficient third-row vehicles on the market. The four-cylinder model gets an estimated 26 mpg highway.

4. 2015 Hyundai Sonata Hybrid

While a minivan or SUV is ideal – and necessary if you have more than two kids – you can get away with a roomy sedan when you still have a small family. And while there are plenty of eco-friendly options in this category, the 2015 Hyundai Sonata Hybrid is arguably the biggest bang for your buck. It gets 38 mpg on the highway and is incredibly affordable.

5. 2017 Land Rover Range Rover Sport Diesel

If money isn’t an object and you’re able to spend any amount to get a good vehicle that’s both comfortable and eco-friendly, the 2017 Land Rover Range Rover Sport Diesel is your car. Not only does it get 28 mpg highway, but it can also be equipped with a third row of seats and a diesel engine. And did we mention that this car looks sleek?

Putting it All Together

You have a variety of options. Whether you want something new or used, would prefer an SUV or minivan, or want something cheap or luxurious, there are plenty of choices on the market. The key is to do your research, remain patient, and take your time. Don’t get too married to a particular transaction, or you’ll lose your leverage.

You’ll know when the right deal comes along, and you can make a smart choice that’s functional, cost-effective, and eco-friendly.
