Footprints to Sustainability | UBC Sustainability | Sustain Our Earth | Scoop.it

Eco-footprinting.... starts from a series of simple premises:

    * People remain integral components of the ecosystems that sustain them;

    * Most human impacts on ecosystems are associated with energy and material extraction and consumption (all economic activity has material consequences);

    * Many energy and material flows are readily measurable and can be converted to corresponding productive or assimilative ecosystems areas;

    * There is a finite area of productive land and water ecosystems on Earth.

Dai tetti verdi alle fonti rinnovabili: svolta green per oltre mille Comuni

Dai tetti verdi alle fonti rinnovabili: svolta green per oltre mille Comuni | Sustain Our Earth | Scoop.it

Crescono innovazione e sostenibilità nel panorama dell’edilizia italiana con una spinta “dal basso”. Sono 1.003 i Comuni italiani individuati nel Rapporto Onre 2013 promosso da Cresme e Legambiente, nei quali si è intervenuti per introdurre nuovi criteri e obiettivi energetico-ambientali rispetto alla normativa in vigore. Sono esperienze che coinvolgono territori dove complessivamente vivono oltre 21 milioni di persone in un processo che accomuna grandi città e piccoli comuni.
I parametri presi in considerazione nell’analisi sono l’isolamento termico, i tetti verdi, l’utilizzo di fonti rinnovabili, l’efficienza energetica degli impianti, l’orientamento e la schermatura degli edifici, i materiali da costruzioni locali e riciclabili, il risparmio idrico e il recupero delle acque meteoriche e delle acque grigie, l’isolamento acustico, la permeabilità dei suoli e l’effetto isola di calore, le prestazioni dei serramenti, la contabilizzazione del calore, la certificazione energetica, le pompe di calore e le caldaie a condensazione, la ventilazione meccanica controllata. Vediamone i numeri.

Is Gasification Better Than Incineration? Read: Global Markets for Gasifiers - WSJ.com

NEW YORK, April 15, 2013 /PRNewswire/ -- Reportlinker.com announces that a new market research report is available in its catalogue:

Global Markets for Gasifiers

Duane Tilden's curator insight, April 15, 2013 9:59 PM

INTRODUCTION

Gasification is a centuries--old thermochemical energy conversion technology that has slowly achieved modernity over the decades. The technology is undergoing its third evolutionary surge. Fuel shortages in WWII spurred widespread adoption for vehicle fuels. The oil crisis 1973 spurred a re--evaluation and renewed development. Rising oil prices, globally increasing fuel demand, and overwhelming scientific evidence of climate change have spurred this last leg to full industrialization.

 

The central concept of gasification is that by raising carbon--rich materials to high temperatures in an oxygen--deficient containment, the material will break down thermochemically instead of burning. If the same material is combusted (burned), it emits carbon monoxide and a host of pollutants, besides being incompletely consumed. If gasified, the products are hydrogen (H2), carbon monoxide (CO) and carbon dioxide (CO2). This is synthetic gas, simply called "syngas." It can be burned, captured, stored, or its molecules rearranged to form fuels and chemical feedstocks.

 

The process is moderately more efficient than incineration, has significantly fewer emissions and waste, and the syngas can be shaped into a myriad of products for power production, chemical industries, liquid fuels, and heat.

 

Feedstock for gasification can be coal, the organic components of municipal waste, industrial waste streams, chemical feedstocks, forestry residues, forest products and crop residues, medical waste, unrecycled plastic or, in the case of plasma gasifiers, almost any nonradioactive material.

 

A gasifier is the central component of a gasification plant. Surrounding it are the feedstock conditioning and delivery systems, oxygen, steam and air input systems, waste removal components, syngas cooling and cleaning systems, power plants, heat recovery units, Fischer--Tropsch molecule rearrangers, and so on. This report focuses on the markets for gasifier units that are in place and will be installed by application segment and geographic location through the year 2017.

Riscaldamento domestico a biomassa, fra vantaggi e disinformazione

Riscaldamento domestico a biomassa, fra vantaggi e disinformazione | Sustain Our Earth | Scoop.it

L'inverno non allenta la sua morsa, malgrado la primavera sia già inoltrata, e gli elevati costi di gas e gasolio spingono le famiglie a cercare alternative più convenienti per il riscaldamento domestico. Una di queste è la biomassa, di cui vogliamo sondare tutti i vantaggi e gli svantaggi celati dalla disinformazione. Tradizionalmente l'Italia è uno dei principali utilizzatori di legna fra i paesi industrializzati. Le statistiche della FAO posizionano il nostro Paese tra i principali importatori, e consumatori di circa 20% della produzione mondiale. Chiederci se il riscaldamento a biomassa sia davvero sostenibile è certamente lecito.

So why don’t we stop pretending there is a mystery? We are poisoning our surrounding waters. Take responsibility and call it what is, a crime!

Aquaponics: Is this promising, sustainable farming method the urbanized future of agriculture? ... Five ways small-scale organic farming can save agriculture from America's 'greed for profit' system • Study: Organic farming ...

Because aquaponics is essentially a closed system, with the exception of fish food having to be cultivated or purchased separately, it can function independently, and without many of the normal inputs required for traditional farming. This means that a well-designed aquaponics system can be installed and operated virtually anywhere, including in dense urban environments -- high-rise rooftops, the tops of parking structures, and even basic parking lots are just a few examples of the many locations where high-output aquaponics systems can work.
This is good news for the many urban farmers with limited access to clean, unpolluted growing soils. A well-designed aquaponics system with stacked growing pods is capable of growing high volumes of fruits and vegetables -- according to Gaus, a 2,700-square-foot greenhouse farm he is currently building on a rooftop in Basel, Switzerland, is expected to produce more than five tons of fresh vegetables and roughly one ton of fish per year.
