These products also offer a smaller cradle-to-gate
environmental footprint than virgin PBT resin, as measured by Cumulative Energy Demand (CED) and Global Warming Potential (GWP).
The Footprint of producing a product is likewise the sum total of negative impacts caused by the processes necessary to produce that product The scope of these processes is called "cradle-to-gate
;" it includes both the manufacturer's operations and all processes of the supply chains such as inputs of energy, materials and equipment.
In this regard, three scenarios are considered as petroleum refinery life-cycle phases (Cradle-to-Gate
, Gate-to-Gate, and Gate-to-Grave), and the criteria are the sustainability factors.
SCA's recently released Life Cycle Assessment Calculator, also part of free site download resources, is used to quantify and interpret cradle-to-gate
LCA environmental impacts of ready-mixed concrete mixtures with and without slag cement.
If wood fuel inputs are derived from another LCI process and carry the upstream impacts of the forest, log yard, and breakdown, then a cradle-to-gate
analysis can be performed.
is the whole phases of Figure 1 except concrete/asphalt plant and construction site/road.
"Solva/s initial cradle-to-gate
assessment shows outstanding results--carbon footprint reduced by a quarter; consumption of non-renewable resources divided by two; and water use decreased by over two-thirds compared to traditional compounds." The firm is taking post-industrial airbags from two suppliers--Takata and Autoliv--and applying a chemistry process that separates the silicone from the PA and then recompounds that nylon into Technyl 4earth.
I will also cover the product's life from cradle-to-gate
, meaning window materials' impact will be measured from raw material extraction to its final form leaving the manufacturer.
It provides a reduction in the cradle-to-gate
carbon footprint for this type of packaging.
Recycled polyester is used in several new products, a process that has reduced our cradle-to-gate
environmental impact by 10%
