Agricultural waste to power Colombian egg farms

German biogas plant specialists Weltec Biopower are to build an 800kW biogas plant for Colombia’s largest egg producer. 

Incubadora Santander’s plant will be fuelled by dry chicken manure and process water from the company’s poultry farms near the western Colombian province of Cauca. In total, the farms produce some 3.5 million eggs daily, which are then sold in 14 different cities across Colombia. The electricity ultimately produced by the plant will be used to power the company’s existing operations.  

The plant will utilise the process of anaerobic digestion, in which organic material is broken down by microorganisms in an airtight container. The process will further produce a fertiliser suitable for use on the company’s own land.

Weltec Biopower has built waste-to-energy plants in Poland, England and Finland, as well as agricultural biogas plants in the Czech Republic, Italy and Uruguay. The company constructs its facilities using stainless steel because the hydrogen sulfide and ammonia produced in the fermentation process can corrode other materials.

Incubadora Santander Manager Montoya Muñoz is keen to expand the brand across the globe using “various measures such as direct investments and strategic alliances”.

“In the coming years, we will step up our production to 10 million eggs a day,” Muñoz said in a statement.

Colombia has a target to produce 6.5 per cent of its on-grid electricity from renewable sources by 2020, as well as a target to source 30 per cent of off-grid power from renewables.

All but two UK regions failing on school energy efficiency

Yorkshire & the Humber and the North East are the only UK regions where schools have collectively reduced how much they spend on energy per pupil

Most schools are still "treading water" on implementing energy efficient technology, according to new analysis of Government data from eLight.

Yorkshire & the Humber and the North East are the only regions where schools have collectively reduced how much they spend on energy per pupil, cutting expenditure by 4.4% and 0.9% respectively. Every other region of England increased its average energy expenditure per pupil, with schools in Inner London doing so by as much as 23.5%.

According to The Carbon Trust, energy bills in UK schools amount to £543 million per year, with 50% of a school’s total electricity cost being lighting. If every school in the UK implemented any type of energy efficient technology, over £100 million could be saved each year.

Harvey Sinclair, CEO of eEnergy, eLight’s parent company, said the figures demonstrate an uncomfortable truth for the education sector – namely that most schools are still treading water on the implementation of energy efficient technology. Energy efficiency could make a huge difference to meeting net zero ambitions, but most schools are still lagging behind.

“The solutions exist, but they are not being deployed fast enough," he said. "For example, we’ve made great progress in upgrading schools to energy-efficient LED lighting, but with 80% of schools yet to make the switch, there’s an enormous opportunity to make a collective reduction in carbon footprint and save a lot of money on energy bills. Our model means the entire project is financed, doesn’t require any upfront expenditure, and repayments are more than covered by the energy savings made."

He said while it has worked with over 300 schools, most are still far too slow to commit. "We are urging them to act with greater urgency because climate change won’t wait, and the need for action gets more pressing every year. The education sector has an important part to play in that and pupils around the country expect their schools to do so – there is still a huge job to be done."

North Yorkshire County Council is benefiting from the Public Sector Decarbonisation Scheme, which has so far awarded nearly £1bn for energy efficiency and heat decarbonisation projects around the country, and Craven schools has reportedly made a successful £2m bid (click here).

The Department for Education has issued 13 tips for reducing energy and water use in schools.
